I was at a local closeout store today and was looking through their light bulbs. I noticed there were some LED specialty bulbs that seem to have the same base/connection and are about the same size as the EFM bulbs on my Sankyo 500.
I think I remember reading about using LED style bulbs here before- what's the scoop? Do you have to do some rewiring or special conversion?

Also beware of possible flickering issue if the bulb has flick of its own and does not match the shutter's frequency; this will most certainly result in a glowing image on screen.

Chad...Maurizio is absolutely correct. LED bulbs even though the voltage and wattage output are equal to the original halogen bulb may not disburse the light properly for projection. In the majority of cases... LEDs have been used more for Telecine work where the image is not projected, but rather captured directly off the film. LEDs run cool and are very suited for this.
However there are examples of LEDs being substituted for Halogen bulbs. I myself now use a LED bulb for projection on my Pathe Baby and Myron Baron on this forum has designed a LED substitution bulb for the CXR bulb used in the Sankyo 1000 and may also work on other projectors using this bulb.
