Major, the new light showed up friday afternoon, and i slapped in the bottom shelve of the grow rack. It has 8 rows of Led's in it on 2 switches so you can run 4 lights, or all 8. It is very, very bright not so much a multicolor light, but more of a pure white light. The lamp does generate a small amount of heat, but its not overwhelming. I've found during the day, my heater doesn't run hardly any at all, the light keeps the rack around 78 degrees. So far i'm liking it and plan to get another for the top rack. I'll move the red/blue spectrum light into my greenhouse, i think the more mature plants would benefit from it more.
