I assumed 300 leds in a 5m strip and picked the higher of the draws between rgb and white.
5 meter led strip wattage.
Conventional 3528 smd power is 0 08w 2835 smd the power is 0 1w or 0 2w and other smd models are.
3014 5630 and so on.
Again this is based on type and length of the light strip.
With 5050 smd 60pcs per meter led strips the power per meter is 14 4w it is because 5050 smd single smd watts 0 24w x smd quantity number 60leds 14 4w m.
Although it s not listed here we can calculate the amperage using the formula p v x a where p is the wattage v is voltage and a is amperage.
14 x 8 5 119 watts in total.
I use one of these ebay item 201217255753.
This checks out because there are 5 meters per reel and 4 8 watts meter 5 meters 24 watts.
The power draw per foot or meter is almost always listed in an led strip s datasheet.
Power 4 watts per ft x 5 ft 20 watts.
All else equal 24v is typically your best bet.
12 volt at 5 amps 60 watts 300 rgb leds.
Example scenario connecting 5 ft of led strip where led strip power consumption is 4 watts per foot.
Step 4 calculate the estimated power usage.
The led strip lists the total wattage as 24 watts or 4 8 watts per meter.
So you need a led power supply sometimes referred to as a led driver that can deliver at least 119 watts.
The led strip has a power consumption of 14w m.
This calculation is important for determining the size of the power supply needed.
It was 10 with shipping and took about 3 days to get here.
However it is recommended that you make allowances for unintentional overloads.
