For the MT-G2, bearing in mind that I have not done an MT-G2 build:
- Mag switch is fine.
- Aluminum heatsink is fine. If you want this light to be a “user” instead of a hotrod, you will have to make do with less than the maximum current. If you’re just hotrodding, DBCstm just assembled a tiny titanium light with an MT-G2, and Ti is a horrible heatsink. The emitter hasn’t died.
- Drivers are an issue, especially depending on cell configuration. The most straightforward would be 2s Li-Ion w/ zener modded Nanjg 105c. My understanding is that the latest DRY driver is bucking in every mode, so that would be an option - RMM has them here. The 32mm DRY driver is a tight fit, but should go in there…
- Aluminum reflector is not necessary.
The only info I know of on the latest DRY driver is here.. RMM said it was operating in buck mode on 3s, so that sounds good.
