Hey guys has anyone ever heard of a better test then
PAR to test how much light an LED gives out?
Ive heard some people say that its not as helpful
because of somethign to do with the blues in LED or something?
im thinking about doing this build up

To create my LED setup...MUCH cheaper and gives me the
flexibility to creat whatever light with what ever features(mostly) that i want :D
thanks

Maybe you mean nm? Par is basically how intense the light is. nm for leds is their colour range. MagicJ has a great writup on this in the diy forum.
