- Preon P2 MKIII (2xAAA) with 4000k. If you do it in slate blue I'd be forced to get P1 (1xAAA) 4000k as well. That seems pretty easy since you are out of stock and due for another run.
- Make a smallest possible 1xAA/14500 light from the ground up patterned after the Preon P1 (1xAAA). Basically a Preon P1 scaled up to fit an AA. I'd be OK with just NiMh capability and the same driver, lumen levels and switch from the 1xAAA Preon, but I think today's market would want 14500 capability and a higher burst to go along with the higher voltage. Make sure a Vapcell 1250mAh will fit and has LVP built in.
- 16650 twisty tube for the Mini MKIII Turbo. You already sell the battery, the head, and you could keep the same clip. It would be have better proportions and easier to hold, lots more battery capacity and still be really small - a backpackers dream!
- UI upgrade: I would like to be able to turn memory on/off/hybrid in the programing
???US made lights cant be feature rich.
