I hate to be the bearer of bad news but the 90 watt LED lights from HTG supply are junk. A good 90 Watt LED light will run you between $300-$500 (mine cost $300). I suggest you return them and purchase just 1 decent 90 watt LED. Check out Prosource worldwide ($300) or HID Hut ($500). LED lights do work you just need to be careful about which model you choose.
