This idea comes from a Spanish projectionist, so the merit is not mine.
After lots of research, he discovered that you can have around 1000-1200 lumens on a GS-1200 by using a MHR-100 HID
lamp. This lamp concentrates the light at around 8mm, so the light is distributed perfectly on screen when adjusted at 32mm from the film path.
This is the lamp:http://www.globalindustrial.com/p/elect ... halidelamp
For the installation, you only need a new lamp holder (I think the HTI lamp holder from Wittner is appropiate, but I'm not sure), and a M90 ballast.
- Very cheap and easy modification.
- 5200º K and around 1000/1200 lumens
- No extra cooling needed
- It lasts 6000 hours!
By the way, I didn't tested this modification as I don't have an Elmo, but he assured me that projecting scope in a 10 meter screen gave mind-blowing results...
ANOTHER INTERESTING THING:
He told me that a Chinese version of this lamp is made on MR16 size, so if we found it, any (ANY!) halogen projector can be modified for this monstruous light output.
What do you think?
