Best resources to learn how to make High Powered LED's work?
What are the best resources for learning how to use high powered LEDs. I want to make my own Night vision IR flashlights and illuminators, but just don't quite have all the parts as to how to do this exactly. Should be extremely simple I think. But, I've found how to calculate the resistors that may be needed, but don't quite understand what a "driver" is or how to figure out what one I need for "X" LED, I want to use. Say, Put 2, 3, 5, 50 or whatever, 5w or whatever the largest LEDs are now......(that I can afford on the cheap).......together and use a 12v source or cr123 or whatever to power them. And just making my own flashlights or converting an old flashlight or making video lighting with white LEDs would be nice. Any advice from any of you would be greatly appreciated.
