   Metal Halide lamps and projectors
  Well, I finally did it. Ordered a 250 watt metal halide HQI lamp and ballist kit This should be the final piece I need for my projector. The two-150-watt incandescents I tried to use at the beginning of my projector project were just too yellow and not bright enough. The 600 watt halogen was plenty bright, but way too hot and still a bit too yellow. This metal halide setup should give me just the right color tempurature, be much cooler than the halogen, and last much longer (mh lasts 10,000 hours, halogen only 75 hours).Anybody here ever have any experience with HQI''s and electronic ballists (like with aquariums and stuff)? What I want to know is if these HQI mh lamps ingnite and burn bright instantly, unlike those core and coil ballists and the big bulbs..
