![]() Okay so I'm running my 400 watt Ushio 10,000k bulb it gives of great light. The ballast however runs MUCH cooler than it did with my other 400 watt bulb. I ran that other bulb for a year and a half with no problems but the ballast (ballast case actually) was always to hot to touch. If I wanted to move it I had to unplug it and let it cool. This time with the Ushio bulb the ballast is just warm, I can touch the case no problems, any ideas or thoughts?
