Step 4 calculate the estimated power usage.
5 meter led strip wattage.
All else equal 24v is typically your best bet.
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.
Conventional 3528 smd power is 0 08w 2835 smd the power is 0 1w or 0 2w and other smd models are.
It was 10 with shipping and took about 3 days to get here.
Again this is based on type and length of the light strip.
Our 5ft length example setup will use 5 12w ft x 5ft 26 5 watts.
14 x 8 5 119 watts in total.
The led strip has a power consumption of 14w m.
Not sure if you should choose between 12v and 24v.
The led strip lists the total wattage as 24 watts or 4 8 watts per meter.
This checks out because there are 5 meters per reel and 4 8 watts meter 5 meters 24 watts.

I use one of these ebay item 201217255753.
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.
12 volt at 5 amps 60 watts 300 rgb leds.
This calculation is important for determining the size of the power supply needed.
3014 5630 and so on.
However it is recommended that you make allowances for unintentional overloads.
So you need a led power supply sometimes referred to as a led driver that can deliver at least 119 watts.
Power 4 watts per ft x 5 ft 20 watts.
