LED grow lights... input please.

PJF: Your angle pread is too wide on those LEDs. I think you should be using a narrower angle for most of those lights around 15º should be okay.

I was told that as long as the mcd rating is high at high angle, they are MORE powerful than a 15 angle.

Example.
660nm, 4000mcd 15 degree angle.
660nm, 4000mcd, 100 degree angle.

This means that I am still getting 4000mcd spread further across the plants. Not in that narrow angle, so in theory those light a more than 4x stronger.
