IMPORTANT: Do you plan to dim your lights?
- If you plan to dim your LED strips using a Lutron or Leviton wall dimmer, you need a Magnitude dimmable driver. This driver itself will be dimmed from the Lutron switch.
- If you do not plan to dim the lights from a wall switch and want to dim them with one of our dimmers, you will need a non-dimmable LED driver. Why? The driver will not be used to dim the lights. The dimmer installed after the lights will do the dimming.
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. If you are on this page, you have selected Colorbright LED single color strips.
Step 2- What length of LED strip light do you need (by the foot)?
Step 3- Use the charts to figure out which LED strip light power supply you need.
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.
