This light can do a lot for its size 100w draw from the wall, will easily cover a 3x3 foot print at 18in over canopy! I would strongly recommend this for a great quantum board choice for a Veg room.
I would compair this to a 4x4 T5. Currently i have this covering two mother plants and they are holding strong, new growth daily.The heat sink is a little small, if it was a little thicker it would help keep it cooler.The dimmer works, at 0 though it does still shine light so best use with a timer tSee full review
