Not sponsored in any way, but since you asked... GrowAnt g3 or g5 series is the way to go. I am trying to convince them to raise their prices! They use Osram LEDs in all of their lights. You can compare their lights to many in the Kind and California light works offerings. I have been a silent supporter for a while, but they have a 50% off coupon on amazon so you would be crazy not to jump! IMHO they compare themselves to such inferior brands that it hurts their reputation. They are marketing a Corvette to a Pinto audience. Check out any of their lights plus the 4 year warranty (that they actually stand behind), and you will see what I am saying.
