90 watt led ufo grow light

I use two of these to assist in light penetration on the flowering cycle. its easy to light up the tops of your plants. whats hard is getting light past all those canopy leaves to the bottom buds and two of these hanging sideways and firing light into the bottoms of the plants. if you decide to buy any of these of ebay please do your homework because there are a lot of cheaply made knockoffs of these lights that are not wired very well and will bring a danger to yourself and your home, be carefull. the ones I chose have 3 fans on the back of them and a lot of the ones I see on ebay only have one big fan on the back. I don't know about you but I like the 3 over the 1 in case of fan failure.
