How Many Watts per Foot Should LED Strip Lights Use?
When choosing an LED strip, one specification appears on almost every product:
Watts per foot (W/ft)
or:
Watts per meter (W/m).
But what does that number actually tell you?
And how many watts per foot should you choose?
As a general starting point, LED strip applications may fall into ranges such as:
| Application | Typical Starting Range |
|---|---|
| Decorative / Mood Lighting | 1–2 W/ft (3.3–6.6 W/m) |
| Shelf / Accent Lighting | 2–4 W/ft (6.6–13.1 W/m) |
| Cove Lighting | 3–5 W/ft (9.8–16.4 W/m) |
| Under-Cabinet Lighting | 4–6 W/ft (13.1–19.7 W/m) |
| Task / High-Output Lighting | 5–8+ W/ft (16.4–26.2+ W/m) |
These are general planning ranges, not fixed requirements.
The best wattage depends on the actual LED strip, its efficiency and lumen output, installation method, desired brightness, room, and application.
Most importantly:
Wattage tells you power consumption—not brightness directly.
Let's look at how to choose the right LED strip wattage.
For reference, our own COB LED strip range spans these bands: 1.83 W/ft (6.5mm), 3.05 W/ft (8mm), 4.27 W/ft (10mm) and 7.32 W/ft (12mm double-row).
What Does Watts per Foot Mean?
Watts measure electrical power.
When an LED strip is rated at:
4 watts per foot
that means approximately one foot of the strip consumes 4 watts at its rated operating conditions.
If you install:
10 feet
your approximate connected load is:
4 W/ft × 10 ft = 40W
If you install:
25 feet
the load becomes:
4 W/ft × 25 ft = 100W
This number becomes extremely important when choosing your:
- LED driver
- Wiring
- Controller
- Dimmer
- Power distribution method
So W/ft is not simply a product specification—it helps determine the design of the entire LED system.
Watts per Foot vs. Watts per Meter
Some manufacturers specify LED strip consumption in W/m, while others use W/ft.
Since:
1 meter ≈ 3.281 feet
you can convert between them.
W/ft to W/m
Multiply by approximately:
3.281
For example:
4 W/ft × 3.281 ≈ 13.1 W/m
W/m to W/ft
Divide by:
3.281
For example:
15 W/m ÷ 3.281 ≈ 4.57 W/ft
When comparing two LED strips, make sure you're comparing the same unit.
Does Higher Wattage Mean a Brighter LED Strip?
Often, a higher-power strip can produce more light—but wattage alone does not determine brightness.
Consider two hypothetical strips:
Strip A
4 W/ft
400 lm/ft
Strip B
5 W/ft
400 lm/ft
They produce the same lumen output, but Strip A uses less electrical power.
Strip A is therefore more efficient in this example.
This is why you should compare:
Watts + Lumens
rather than watts alone.
Lumens per Watt Matter
A useful efficiency measurement is:
Lumens per Watt (lm/W)
Suppose a strip consumes:
5 W/ft
and produces:
500 lm/ft
Its efficiency is:
500 ÷ 5 = 100 lm/W
Now imagine another strip consumes the same:
5 W/ft
but produces:
350 lm/ft
Its efficiency is only:
70 lm/W
Both use the same amount of electricity.
But one produces significantly more visible light.
So when choosing a strip, don't ask only:
“How many watts does it use?”
Also ask:
“How many lumens does that wattage produce?”
Worked from our published figures, the 6.5mm Ultra Slim runs about 123 lm/W (225 lm/ft on 1.83 W/ft) while the 12mm Double-Row runs about 87 lm/W (635 lm/ft on 7.32 W/ft). The brighter strip is the less efficient one per watt — it simply draws four times the power.
1. Decorative and Mood Lighting: 1–2 W/ft
For subtle decorative lighting, very high power may not be necessary.
Applications can include:
- Headboard lighting
- TV backlighting
- Decorative niches
- Soft shelf lighting
- Bar accents
- Low-level ambient lighting
A starting range around:
1–2 W/ft
or:
3.3–6.6 W/m
may be sufficient for some applications.
The goal isn't to illuminate the entire room.
It's to create:
Atmosphere + Depth + Visual Interest
If the strip is dimmable, you can also adjust the final effect.
Our 6.5mm Ultra Slim COB Strip sits in this band at 1.83 W/ft (6 W/m).
2. Shelf and Accent Lighting: 2–4 W/ft
For shelves, displays, and architectural accents, you may need more output.
A general starting range could be:
2–4 W/ft
or approximately:
6.6–13.1 W/m
This range may work well for:
- Floating shelves
- Display cabinets
- Bookcases
- Wall niches
- Entertainment centers
- Decorative millwork
However, brightness depends heavily on the actual lumen output of the strip.
A high-efficiency 3 W/ft strip could potentially outperform a less-efficient 4 W/ft strip.
The 8mm Indoor Dotless COB Strip falls here at 3.05 W/ft, producing 250–270 lm/ft.
3. Cove Lighting: 3–5 W/ft
Cove lighting often requires more output because the light is indirect.
Instead of shining directly into the room, the COB strip typically illuminates:
Ceiling → Wall → Room
Some light is absorbed during reflection.
For this reason, a starting range around:
3–5 W/ft
or:
9.8–16.4 W/m
may be useful for many cove applications.
But several factors can change the required output:
- Cove depth
- Distance from ceiling
- Ceiling color
- Room size
- Ceiling height
- Strip angle
- Desired brightness
A large room with dark finishes may require a very different strip from a small white room.
Both ends of this band are covered: the 8mm at 3.05 W/ft for a typical residential cove, and the 10mm at 4.27 W/ft for larger rooms, higher ceilings or darker finishes.
4. Under-Cabinet Lighting: 4–6 W/ft
Under-cabinet lighting often serves a functional purpose.
It needs to illuminate:
Countertops
Food preparation areas
and other work surfaces.
A starting range around:
4–6 W/ft
or:
13.1–19.7 W/m
may be appropriate for many higher-output under-cabinet applications.
But again, check the actual lumen rating.
For kitchen lighting, you should also consider:
- CRI
- Color temperature
- Mounting position
- Countertop reflectance
- Diffuser
- Dimming
A well-designed 4 W/ft COB strip can sometimes provide a better result than simply choosing a higher-wattage product.
Our 10mm Indoor Dotless COB Strip is the product built for this band — 4.27 W/ft delivering 340–415 lm/ft at CRI ~90, which is squarely in the under-cabinet range on both specifications.
5. Task and High-Output Lighting: 5–8+ W/ft
Some projects need considerably more light.
Examples include:
- Workbenches
- Commercial displays
- High-output architectural profiles
- Large indirect-lighting systems
- Work surfaces
- Certain primary-lighting applications
Higher-output strips may consume:
5–8+ W/ft
or:
16.4–26.2+ W/m
depending on the product.
At these power levels, thermal management becomes increasingly important.
You should pay close attention to:
Aluminum Channels + Driver Capacity + Wiring + Voltage Drop + Installation Temperature
The 12mm Double-Row High-Brightness COB Strip is our product in this tier at 7.32 W/ft (24 W/m), producing 545–635 lm/ft.
Higher Wattage Means More Heat
LEDs are efficient, but they are not 100% efficient.
Some electrical power becomes visible light.
The rest becomes heat.
As strip power increases, thermal management generally becomes more important.
For example, compare:
2 W/ft COB Strip
with:
7 W/ft High-Output COB Strip
The higher-power strip has considerably more electrical energy passing through each foot of the installation.
Its mounting method therefore deserves greater attention.
That comparison is almost exactly our 6.5mm Ultra Slim at 1.83 W/ft against the 12mm Double-Row at 7.32 W/ft — four times the power through each foot of strip.
Why Heat Matters
Excessive operating temperature can affect:
- LED lifespan
- Light output
- Color stability
- Adhesive
- PCB
- Nearby materials
- Overall reliability
A high-output strip should not simply be attached to any convenient surface without considering thermal performance.
Should High-Wattage COB Strips Use Aluminum Channels?
For many permanent, higher-output installations, aluminum LED channels are highly useful.
The aluminum profile can help:
- Spread heat
- Protect the strip
- Keep installation straight
- Hold a diffuser
- Create a professional finish
This is especially valuable with high-output COB strips operating for many hours per day.
However, always follow the strip manufacturer's thermal and installation requirements.
COB Does Not Mean Zero Heat
COB LED strips create a smooth, continuous-looking line of light.
But they still generate heat.
A common misconception is:
COB = Cool enough to install anywhere
That isn't true.
COB refers to the LED construction and packaging approach—not an absence of thermal considerations.
The actual heat generated depends heavily on:
Power Consumption + Efficiency + Installation + Ambient Temperature
Wattage Determines Driver Size
One of the most important reasons to understand W/ft is driver sizing.
Let's say your COB strip uses:
4.5 W/ft
and you need:
20 ft
Calculate:
4.5 × 20 = 90W
Your connected LED load is approximately:
90 watts
Now you need a driver with the correct:
- Output voltage
- Power capacity
- Dimming compatibility
- Environmental rating
- Other required specifications
Don't choose a driver before calculating the strip load.
A 90W load wants a 150W 5-in-1 driver rather than a 100W unit running at 90% of its rating. For reference, 20ft of our 10mm strip at 4.27 W/ft comes to roughly 85W.
Example: 30 Feet of COB Strip
Suppose the strip uses:
5 W/ft
and you need:
30 ft
Total:
5 × 30 = 150W
That doesn't automatically mean you should select a driver based solely on the exact 150W number.
You also need to consider the driver's loading requirements and the system design.
Depending on the project, you might use:
One appropriately sized driver
or:
Several smaller drivers
The best choice depends on load distribution, cable distance, zones, and control requirements.
A 150W load is a case for the 200W 5-in-1 driver, or for splitting the run across a 192W dual-output transformer if the two halves sit some distance apart.
Should You Add Extra Driver Capacity?
A design margin can be useful, but don't apply one universal percentage blindly to every driver.
Different drivers have different:
- Rated loads
- Continuous-load requirements
- Dimming characteristics
- Manufacturer instructions
For example, installers sometimes plan around an 80% loading approach where appropriate.
Under that approach:
100W LED Load → approximately 125W driver capacity
because:
100 ÷ 0.8 = 125W
But treat this as a planning example, not a universal rule.
Always follow the specifications for the actual driver.
In practice the next size up from 125W in our range is the 150W 5-in-1.
Wattage Also Affects Current
The basic electrical relationship is:
Power = Voltage × Current
Therefore:
Current = Power ÷ Voltage
Suppose your installation consumes:
120W
At:
12V
120 ÷ 12 = 10A
At:
24V
120 ÷ 24 = 5A
The same wattage requires half the current at 24V compared with 12V.
This is one reason 24V LED strip systems are often practical for larger installations.
Every COB strip in our range runs at 24V for this reason.
Why Current Matters
Higher current can affect:
- Wire size
- Voltage drop
- Connectors
- Controllers
- Distribution
- Maximum practical run lengths
So LED strip wattage doesn't only determine your electricity consumption.
It influences the entire electrical design.
High Wattage + Long Run = More Planning
Suppose you have a:
6 W/ft COB strip
running for:
30 feet
Total load:
180W
At 24V, the theoretical current is:
180 ÷ 24 = 7.5A
Trying to feed that entire installation through long undersized wiring or one poorly planned connection can create problems.
Long, high-power installations may require:
- Parallel wiring
- Multiple feeds
- Power injection
- Multiple drivers
- Larger conductors
depending on the product and project.
A multi-output unit such as the 192W Dual-Channel or 288W Triple-Output Transformer handles this by giving each section its own terminated feed.
Wattage Does Not Determine Maximum Run Length by Itself
A common mistake is thinking:
“My driver has enough watts, so I can run the strip as long as I want.”
Not necessarily.
Maximum strip run length can also depend on:
- Strip PCB design
- Voltage
- Current
- Copper thickness
- Voltage drop
- Feed location
- Manufacturer specifications
A 300W driver might theoretically have enough power for a large quantity of strip, but that doesn't mean all of that strip should be connected as one continuous run.
Example: Driver Capacity vs. Strip Run
Imagine:
Strip = 5 W/ft
Driver = 200W
Mathematically:
200 ÷ 5 = 40 ft
But this does not automatically mean:
One continuous 40-foot strip run is acceptable.
The manufacturer might specify a shorter maximum feed length.
You may need:
Parallel Runs
or:
Power Injection
to distribute power correctly.
Where a genuinely long single run is unavoidable, a line-voltage product such as the 100ft 110V COB Strip sidesteps the low-voltage run-length limit entirely.
What Is Power Injection?
Power injection means supplying power at additional points along a long LED strip installation.
Instead of:
Driver → 40 ft Strip → End
you might design:
Driver → Beginning
and:
Driver / Distribution → Additional Feed Point
This can help reduce brightness loss caused by voltage drop.
The appropriate method depends on the strip and system design.
A 288W Triple-Output Transformer provides three separate feed points from a single enclosure, which is often simpler than field-splicing injection points.
Can Lower-Wattage Strips Run Longer?
Sometimes lower-power strips can be easier to operate over longer distances because they draw less current.
But maximum run length still depends on the product design.
Do not assume that a low-wattage strip can run indefinitely.
Always check the manufacturer's recommended maximum run length.
Watts per Foot vs. LED Density
LED density tells you how many LED chips or light-emitting elements are distributed along the strip.
Wattage tells you how much electrical power the strip consumes.
These are different specifications.
For example:
More LEDs per Meter
does not automatically mean:
More Watts per Foot
or:
More Lumens per Foot
The individual LEDs may be driven at different power levels.
This is why product comparison should include:
Wattage + Lumens + Density + CRI + CCT
rather than only one specification.
A direct example: our 10mm white strip uses 480 LEDs/m at 4.27 W/ft and produces up to 415 lm/ft, while the RGB COB strip packs 630 LEDs/m and draws more power at 5.5 W/ft, yet produces only about 210 lm/ft. More LEDs, more watts, less light.
Watts per Foot vs. Lumens per Foot
These two numbers work together.
Watts per Foot
How much electrical power the strip consumes.
Lumens per Foot
How much visible light the strip produces.
Together, they help you understand efficiency.
For example:
Product A
4 W/ft → 400 lm/ft
Product B
5 W/ft → 400 lm/ft
Product A delivers the same listed light output while consuming less power.
This is why the brightest or highest-wattage strip isn't automatically the best strip.
Every product page in our COB strip range lists both figures at each colour temperature so you can work out lm/W before ordering.
What About CRI?
CRI measures how accurately colors appear under the light.
A strip could be:
Very Bright + High Wattage
but still not provide the color quality you want.
For residential interiors, kitchens, retail displays, and architectural applications, 90+ CRI can be desirable.
When comparing LED strips, think about:
Brightness + Efficiency + Color Quality
together.
Our COB strips are CRI ~90 throughout, so the choice between them comes down to output and width rather than colour quality.
Does Color Temperature Change Wattage?
A strip's color temperature and power consumption are separate specifications.
You may find COB strips in:
- 1800K
- 2200K
- 2700K
- 3000K
- 4000K
- 5000K
- 6500K
Different versions may have somewhat different electrical or lumen specifications depending on product design.
Never assume that every color temperature in a product family has identical output.
Check the specifications for the actual version you're buying.
Our 10mm strip is a good illustration: identical 4.27 W/ft across the range, but 340 lm/ft at 2700K rising to 415 lm/ft at 5000K. Same power, 22% more light. The 1800K Golden Yellow is a separate product with its own specifications.
What About Tunable White COB Strips?
CCT-adjustable strips contain multiple color-temperature channels.
For example:
Warm White + Cool White
A controller blends the channels to create different white tones.
For these products, pay close attention to how the manufacturer specifies:
- Maximum wattage
- Per-channel power
- Total load
- Controller capacity
- Driver capacity
Don't size the driver based on assumptions from a single-color strip.
Our CCT COB LED Strip pairs with a CCT driver with built-in controls, which handles both channels and the driver capacity in one unit.
What About RGB and RGBW Strips?
The same principle applies.
An RGB or RGBW strip has multiple channels.
Its power consumption can change depending on which channels are active.
For example:
Red only
may consume less power than:
Multiple channels operating simultaneously.
Size the power system according to the product's specified maximum load.
For our RGB COB Strip that figure is 5.5 W/ft — size the driver against that, not against the draw at whatever colour you happen to be running. The same applies to the RGBW COB Strip, which adds a fourth channel.
How Much Power Does a 16.4-Foot LED Strip Use?
It depends entirely on its W/ft rating.
For example:
2 W/ft
16.4 × 2 = 32.8W
4 W/ft
16.4 × 4 = 65.6W
5 W/ft
16.4 × 5 = 82W
6 W/ft
16.4 × 6 = 98.4W
Two LED rolls of exactly the same length can have dramatically different power requirements.
Across our own 16.5ft rolls that means roughly 30W for the 6.5mm, 50W for the 8mm, 70W for the 10mm and 120W for the 12mm double-row.
How Much Power Does a 5-Meter LED Strip Use?
Again, check W/m.
Suppose a strip consumes:
15 W/m
For a full 5-meter roll:
15 × 5 = 75W
If another 5-meter strip consumes:
8 W/m
its total is only:
40W
Same physical length.
Very different electrical load.
How Much Does LED Strip Wattage Cost to Run?
Let's use a simple example.
Suppose your complete LED strip installation consumes:
100W
That's:
0.1 kW
If it runs:
5 hours per day
daily energy use is:
0.1 × 5 = 0.5 kWh
Over 30 days:
0.5 × 30 = 15 kWh
Your actual cost depends on your electricity rate.
If the same system operates 24/7:
0.1 × 24 × 30 = 72 kWh/month
So both wattage and operating time determine energy consumption.
Should I Always Choose the Lowest-Wattage Strip?
No.
A low-wattage strip may save energy, but it may not produce enough light for your application.
Imagine trying to illuminate a kitchen work surface with a very low-output decorative strip.
It might consume little electricity—but fail at its actual job.
The goal is:
Enough Light with Reasonable Power Consumption
not simply:
Lowest Possible Wattage
Should I Choose the Highest-Wattage Strip?
Also no.
A high-output strip may create:
- Unnecessary brightness
- More heat
- Larger driver requirements
- Higher energy consumption
- Greater current
- More demanding thermal management
For subtle shelf lighting, an 8 W/ft strip could be unnecessary.
Match the strip to the application.
A Dimmable Strip Can Give You More Flexibility
For some projects, choosing an appropriately bright strip and using a compatible dimming system gives you flexibility.
For example:
100% — Task Mode
60% — Everyday Lighting
30% — Evening Ambience
10% — Night Lighting
This can be particularly useful for:
- Kitchens
- Living rooms
- Cove lighting
- Bedrooms
- Hospitality spaces
But the driver, dimmer/controller, and strip all need to be compatible. Our 5-in-1 dimmable drivers accept TRIAC, ELV, MLV, 0–10V and PWM.
Under-Cabinet Example
Suppose you have:
12 ft of COB strip
rated at:
4.5 W/ft
Total load:
12 × 4.5 = 54W
This is a relatively manageable system.
But if you have a large kitchen with:
35 ft
of the same strip:
35 × 4.5 = 157.5W
Now driver sizing, wiring, power distribution, and possible zoning become much more important.
Same strip.
Different project scale.
In our range that first case is 12ft of the 10mm strip at roughly 51W, comfortably within an 80W driver. The 35ft case comes to about 150W and needs a 200W driver or a split across zones.
Cove Lighting Example
Suppose your room requires:
60 ft
of COB strip rated at:
4 W/ft
Total:
60 × 4 = 240W
Instead of automatically selecting one large driver, consider:
- Strip maximum run length
- Cable distances
- Voltage drop
- Power injection
- Driver locations
- Multiple zones
- Dimming requirements
Large installations should be designed as systems, not simply calculated as one wattage number.
A 240W perimeter is a natural fit for the 288W Triple-Output Transformer, which splits the room into three separately fed runs from one location.
Commercial Example
Imagine a retail project with:
200 ft of LED strip
rated at:
5 W/ft
Total theoretical LED load:
1,000W
This is clearly no longer a simple plug-in lighting project.
The system may need to be divided into:
Multiple Drivers + Multiple Zones + Proper Distribution
with careful attention to electrical design.
This is where watts per foot becomes a critical planning specification.
At that scale you are looking at several 300W drivers or 384W 4-channel units rather than one supply.
12V vs. 24V: Does Wattage Change?
If two strips are both rated at:
5 W/ft
they consume the same power per foot regardless of whether one is 12V and one is 24V.
But their current differs.
For one foot:
12V
5W ÷ 12V ≈ 0.42A
24V
5W ÷ 24V ≈ 0.21A
The 24V strip requires approximately half the current for the same power.
For longer runs, this can be advantageous.
If a project involves both voltages, a selectable driver such as the 60W 5-in-1 can be set to either output.
Why 24V Is Popular for Architectural COB Lighting
24V systems are commonly used for longer architectural LED strip applications because lower current for the same wattage can make power distribution more manageable.
This can help with:
- Longer practical runs
- Voltage-drop management
- Wiring
- Higher-power installations
But 24V does not eliminate the need for proper system design.
How to Choose the Right Watts per Foot
Use this process.
Step 1 — Define the Application
Is the strip for:
Decorative
Accent
Cove
Under-Cabinet
or:
Task Lighting?
Step 2 — Determine the Brightness You Need
Look at:
Lumens per Foot / Lumens per Meter
not just wattage.
Step 3 — Check Efficiency
Compare:
Lumens per Watt
where specifications are available.
Step 4 — Calculate Total Load
Use:
W/ft × Total Feet
Step 5 — Choose the Driver
Match:
- Voltage
- Capacity
- Dimming
- Environment
Every product page in our drivers and transformers range lists all four.
Step 6 — Check Maximum Run Length
Don't assume driver capacity determines strip run length.
Step 7 — Plan Heat Management
Especially for higher-wattage strips.
Step 8 — Plan Wiring and Power Injection
For long or high-power installations.
This gives you a much more reliable design than simply choosing the highest wattage available.
Quick Wattage Guide
Decorative / Mood
1–2 W/ft
3.3–6.6 W/m
Best for:
Soft accent lighting and decorative effects.
Shelf / Accent
2–4 W/ft
6.6–13.1 W/m
Best for:
Shelving, displays, and architectural details.
Cove Lighting
3–5 W/ft
9.8–16.4 W/m
Best for:
Indirect ceiling and wall lighting.
Under-Cabinet
4–6 W/ft
13.1–19.7 W/m
Best for:
Kitchen counters and brighter work surfaces.
Task / High Output
5–8+ W/ft
16.4–26.2+ W/m
Best for:
High-output architectural and task applications.
Again, these are general starting ranges, not universal requirements.
Measured against these bands, our range runs: 6.5mm at 1.83 W/ft, 8mm at 3.05 W/ft, 10mm at 4.27 W/ft and 12mm double-row at 7.32 W/ft — one product per band.
Common Mistakes When Choosing LED Strip Wattage
Avoid these common mistakes:
- Choosing by wattage alone
- Ignoring lumen output
- Assuming higher wattage always means better
- Ignoring heat
- Using an undersized driver
- Ignoring voltage drop
- Ignoring maximum strip run length
- Using undersized wiring
- Forgetting controller capacity
- Running high-power strips while rolled up
- Ignoring aluminum-channel requirements
- Assuming 12V and 24V behave the same on long runs
A reliable installation requires more than matching one number.
Watts vs. Lumens: Which Specification Is More Important?
They answer different questions.
Watts Tell You:
How much electrical power does the strip use?
Lumens Tell You:
How much visible light does it produce?
You need both.
If you're deciding how bright the strip should be:
Look at lumens.
If you're sizing:
Driver + Wiring + Controller + Electrical Load
look at watts.
For a well-designed system, evaluate them together.
Final Thoughts
So, how many watts per foot should LED strip lights use?
As a practical starting point:
1–2 W/ft may work for subtle decorative lighting.
2–4 W/ft may suit shelf and accent lighting.
3–5 W/ft can be useful for many cove-lighting applications.
4–6 W/ft may suit brighter under-cabinet lighting.
And:
5–8+ W/ft may be appropriate for high-output or task applications.
But don't choose your COB LED strip based on wattage alone.
The best choice balances:
Wattage + Lumens + Efficiency + CRI + CCT + Heat + Driver Capacity + Run Length
A professional LED installation isn't about using the most power.
It's about using the right amount of power to produce the right amount of light.
Compare the published W/ft and lm/ft figures across our COB LED strip range to find the one that matches your application.
FAQ
How many watts per foot is a good LED strip?
It depends on the application. Decorative strips may use around 1–2 W/ft, while brighter under-cabinet, architectural, or task strips may use roughly 4–8+ W/ft.
Is 5 watts per foot a lot for an LED strip?
5 W/ft is relatively high compared with low-power decorative strips, but it can be appropriate for brighter cove, under-cabinet, or architectural lighting depending on the strip's efficiency and installation.
Does higher wattage mean a brighter LED strip?
Not necessarily. Higher wattage often allows greater output, but actual brightness should be compared using lumens per foot or lumens per meter.
How do I calculate total LED strip wattage?
Multiply the strip's wattage per foot by the total installed length. For example, 4 W/ft × 20 ft = 80W.
How many watts does a 16.4-foot LED strip use?
It depends on the strip. A 4 W/ft strip would use approximately 65.6W over 16.4 feet. Our 10mm strip at 4.27 W/ft comes to about 70W per 16.5ft roll.
Does a higher-wattage LED strip get hotter?
Generally, higher power density can produce more heat, making thermal management increasingly important.
Should COB LED strips be installed in aluminum channels?
Aluminum channels can be especially beneficial for higher-output permanent installations because they help spread heat while providing protection and a clean finish.
Is 24V better than 12V for high-wattage LED strips?
For the same wattage, 24V requires approximately half the current of 12V. This can make 24V useful for many larger architectural installations, though proper wiring and power distribution are still required.
How do I choose an LED driver based on watts per foot?
Calculate the total strip wattage, then choose a driver with the correct voltage and sufficient capacity according to the driver's specifications and applicable installation requirements.
Should I compare watts per foot or lumens per foot?
Compare both. Watts tell you power consumption, while lumens tell you visible light output.
