The M3 is a great light. You have a few options that I know of.
1. Get an LED tower for the M3 Head. This will be much less than 1,000 Lumens, like 250-300. (Malkoff and kuku427 make them.)
2. Disassemble the M3 bezel and install a D36 module. (
Nailbender makes them. I'm not sure that he has drivers that run 9v, so you'll need to make sure that you can run an appropriate voltage.)
3. Get an M-Series Turbo Head from Lumens Factory.
If you have an M3T, there are some other options, like a higher output tower (Malkoff MD-60) or some very high output incan bulbs.
