LED grow lights... input please.

I got my new LED box finished today, it's fuckin awesome. I'll be moving the girls into their new home after their dark cycle is over. I should have some valid test results for you guys in the coming days/weeks. ;)

MonkeyRacket,

Nice setup, can't wait to see how they come out.

BTW: For those building their own, here is a useful link I found.

What about the blues? Are they ok?

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.

OK, I apologize...don't think I ever read this...still haven't, but I am going to. I breezed through 1st page and don't know where this is going...so, here goes.

Turtle...I want a bigass one with blue and red/full spectrum and I want a green one so I can go play in my room during the 'dark' photoperiod.

Once I read the thread, this request will probably be moot...
gotta go, bro, lw

Lumens = Candelas*2pi*[1â??cos(theta)]
That makes it 0.85 vs. 29.5 lumens... about 30 times better.
