I have burn out, 8 ushio bulb 1000w , i have lumatek ballast and they burn , i have a regular general electric bulb and it run right but the ushio only work for like 1 day or like 3 weeks
hhmm..... Id suspect your equipment is at fault. A company really couldnt stay in business selling mostly defective stuff
im running an ushio 600 in my lumatek as we speak, no problems at all.
