I just ordered two EYE 400-watt MH Conversion lamps (4500 K, 37,500 initial lumens), for $35 a pop from '1000 Bulbs' ... as you know, they are made to ignite with a HPS ballast ... but, one thing I couldn't find in my research, should I expect it to burn much hotter than the present regular Sodiums ? ... :smokin:
