I have never looked @ it in that aspect it is a very good one one I really like I just tried to convience Vicki that I have a 744 Watt T5 Setup I did for a customer that I have since upgrades to a 400 Watt LED system avaiable for a expeiment. She does want to run that test against her 750 Watts of HQI because of the cost of electricity. I dont blame her I convinced her HQI are a thing of the past like treating with copper
