STOP! DO NOT BUY THAT LIGHT!
The claims are outrageous and impossible.
1) 125 watts = 1000 watt HID comparison... Absolutely not. 125 watts of crap LED = less than 125 watts of HID.
2) 12 plants? Yes 12 plants in solo cups.
3) It doesn't even say what watt the diodes are... 3w would be considered crap.. 5w would be normal for two years ago. Now everything is COB.
There is no such thing as bargain when it comes to LED. Good LED is EXPENSIVE. Crap LED is crap and grows crap weed and it still costs 3 times more than HID,, NOBODY is using those types of lights anymore.
Six 23 watt CFL's per plant or 1 4ft 8 bulb t5 HO would work much better and cost only a fraction.
If you want real LED then check out area 51. You will need 1 per plant. Notice Area 51 is sold out right now. It's because they have the best product.

Do yourself a huge favor and just get a 400w or 600w ipower HID from amazon for $120. You will grow awesome bud with that. There is no substitution for HID unless you pay a lot of money from a top manufacturer or build yourself.
