Nice flashlight, and very nice review. I am still resisting upsizing from 18650s, but I can see the appeal here.
I’m thinking you can probably tune out the donut hole in that beam without an OP reflector. I’ve never heard of the SST70 causing a meaningful dead spot in the beam. Maybe try different centering gaskets. It’ll use XML gaskets…
I ordered an SST-70 w/ boost driver to mod a YooToo SD3. I’m expecting some heat (30+ Watts). Didn’t know of donut hole issues w/ Luminus offerings.
It’s the proverbial wait on my orders that take the enthusiasm out. Won’t see the project till the end of the month…
Oh wow.
It's Convoy M21C with a different name...
