Hi there, I am looking to make a small backup light that uses a single 16340 battery.
I am not sure what kind of LED emitter I should be using, or what driver will work best with the single 16340.
I am aiming to have a decent throw, maximize my run time, but try and get 300 - 350 lumens out of the light.

Which LED emitter would be the most efficient?

Here is what I have so far:

Momentary forward tail switch

Biscotti Firmware

AR coated glass

Pocket Clip

No glow O-ring

Nichia 219C? or X-PL HI or XML2?

8×7135 Driver? or 3×7135 Driver?

Orange peel reflector?

Color (Desert Tan)?


Any other suggestions you could add?

Thanks

Well, the convoy biscotti driver will work with any 1s li-ion battery. IF you have any concern about runtime I would avoid the 7135x8 configuration. I'd have to do some searching on drive currents and LED outputs to narrow down exactly what led would need how many chips to get your 350 lumens though I would think the 7135x4 with a SST20/219C/LH351D would get close at max output.
