What DIY replacement bulb should I use?

iCrazyNoob · 16th December 2011, 10:55 AM

Just got a dead Hitachi PJ off ebay and bypassed the ballast inside. I have tried a 20W 12V halogen bulb but its so dim I can barely see in a completely dark room.

Is there a good cheap bulb that can produce decent amount of light to power this projector?

since the projector no longer has a ballast inside, I have a lot of room to stuff a driver/power supply in if needed.
