Mag 2C build question

@Senna Fan

I have a driver question.

If I change from a 6v to a 3v xhp70.2 with a single cell, do I even need to use a driver? Can the emitter handle a fresh 4.2v cell? Assuming I can direct drive the light, are there performance differences going with or without?

as mentioned no 3v xhp70,but a 3v xhp50 would be an easy build

here’s my MAG 3D xhp70 build for some ideas.
