The led e27/g10/ect bulbs have the drivers built in. If the true watted (what's used) isn't listed expect it to be 1/3-1/2 of the listed wattage.
The 14w panel "might" grow lettuces/herbs? I think I saw a video were a 21w-ish grow some lettuces.
It's only 5.8 Watts for $25+ that's $4~/watt not good at all.
If you have a heatsink (like an old CPU) I would suggest something like this: http://www.ebay.com/itm/181164742072?var=480272425249&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 their easy to make just need alittle thermal...
I'm sure the cree version is better but it's like 50% higher cost :/ seeing how I could use 2-3 the cost would add up.
$6 - 50w multi chip
$13 - driver? http://www.ebay.com/itm/50W-Watt-High-Power-LED-Driver-AC85V-265V-50-60HZ-Waterproof-/160927171811?pt=LH_DefaultDomain_0&hash=item257801c4e3...
Thanks.
I just set up the CFL's seems to be about the right amount of light but at some point I'd like to replace them with 20-50w COB's just got to find a place that sells them.
Thinking of doing half the total wattage in led (red/blue) and half with CFL's would the white wavelength from the cfl's mess up the whole PAR thing?
It wouldn't have the pinkish light I see (just about) everyone else doing but it (the red/blue wavelengths) should still be there right? just...
I've been doing some research (gong build my own led grow light) and most people seem to agree Cree leds are the best (because they have the best lm/w?) but there are many different type's/series and I can't find a use this -> "one" for grow lights.
Near every guide/diy I've read uses a...
