Thanks KT Im gonna use the E Hurtilux bulbs. I can get them 57.00 for a 600 and 47.00 for a 400. Hurtilux makes a 1000 watt bulb thats both MH and HPS in one bulb. but its only made in 1000.. Ill run HID in the winder and LED in the summer.. i was just wondering if anyone has used them with autos..
