Choose what size you need-3 easy steps to finding your correct power supply
Since our LED lighting products are customizable and come in different sizes, the power supply you need will depend on the LENGTH and TYPE of the LED flex strip light you are using for your project. The correct power supply needed for your LED lighting project is easy to calculate. Look at the charts below to see which power supply you need.
Step 1 Which LED strip light brand will you use?
The first step is to choose which flexible LED strip light you are going to use for your project.
Use the key below to see which power supply you will need. Look below and find the number of feet you are going to use. Then look across to the final column for the recommended LED power supply to use.
The power source needed depends on the length that you cut the LED strip. Let's use the 150 LED RGB strip light as an example: Each foot uses 2.2 watts. Add the amount of feet together, multiply by 2.2, and you have the wattage used. You should add 20% more room in the power supply so take the wattage, and divide by .8 to get the power supply needed.
Example. 8 feet of RGB LED strip light. 8 X 2.2 watts = 17.6 total watts used. 17.6/.8= 22 watts. You need a power supply that will handle 22 watts.
Coming soon - However you can add the 5.2 watts per foot X the number of feet you need. Take that number and divide by 24 and you get the amps needed.
