I have been thinking since I have so little heat problems about stepping up the bulb. My box is more than big enough to handle it. Does anyone know of a pulse strike lamp that is slightly larger in wattage than the 400w one we sell in the store? Heck if I put another fan in the box I am sure I could run a 1000w bulb.

Phillips make a 575, 700, 1000, 1200, 2500, 4000, 6000 and 12000. And a lot of others, in varying wattages. I'm sure there is one for you somewhere.

12000 watt, 1,200,000 lumens, imagine the heat there.

so help me out here, we use a high pressure sodium bulb? or a metal halide.

i suppose we want to keep a high color rating, around 4 or 5k

i found this pulse start bulb, it is only 50watts more and it gives out 50,000 lumens, or a mean lumens of 40,000 this is 30 percent more average light output than the bulb we currently use and it is only 50 watts increase, or a little over 10 percent, should not be much more heat.

they also offer other bulbs with UV protection. The only difference I see is the mounting is plus/minus 15 base up which i understand to be the mogul of the bulb would have to be on the bottom of the projector.

33 dollar bulb, same stats, a coil type ballast for 66 bucks, this could be a 110 buck package with a mogul. This isnt even considering the chance we get a group buy.

Being an ED37, that lamp is huge.

how big is huge? I have 15 inches of space on the inside of my projector enclosure, if the light source was within 7 inches of the base I might be able to fit it straight up and down and keep the light on the center axis

most of the ed37's ive been finding are 11.5 inches long with a light center length of 7 inches. here are the stats for a bulb

You want MH for sure, not HPS. Search for ED28. 28 refers to the lamp size. Its a smaller lamp physical size.

Right. HPS have a WAY wrong color temp. Usually around 2100K. You want at least 4000K.

40k mean lumens.. That's fantastic. If you could mount that one (base up?... yuk), it would make a good light source.

Is your picture that dark to warrant needing to do this BTW? Have you tweaked it out already?
