Constant Current & Voltage Power Supplies

In this video I look at the two types of power supplies used in led grow lights – constant voltage and constant current. I explain when you should use each type, and what will happen if you use the wrong type for your led grow light.

This video will be very useful for anyone making a DIY light or repairing a damaged light, as well as anyone who just wants to understand what is going on in their light.
