Can’t find these CCT at 3V in high Cri and standard sizes.Let me know if you find others source
I would use them on small host, maybe the boost driver is too large
Can you find a better spring solution for the M3 light? I think others have noticed it also but with the single spring in the tail it just isn't strong enough to keep the weight of the 26650 cells in contact with the brass button on the driver when set down on the tail, so the light cuts out. I notice with mine that if I'm on moonlight and set it down gently, it will cut out and actually shut off the light. On any normal/higher mode it will blink but not shut off. I've tried stretching the spring but of course that wasn't enough. It seems like at the base of the spring coils there is about 2-3mm of space that the spring will lower into as weight is put upon it, reducing the spring length maybe extra than was designed? But with the brass button on the driver instead of a spring, there is no give/support for when the battery moves in the tube. The spring quality is excellent, maybe just needs to be longer or made of thicker wire? Someone posted a photo here where they cut a small piece of rubber tubing to put below the spring to limit its travel/compression but that seems less than ideal solution. It's a minor but important small defect in an otherwise wonderful flashlight design.
It might end up having different mode groups than the regular 12 group driver, I don’t think he ever posted what the final modes are going to be. The 0.1% mode wasn’t going to be included because it wouldn’t work for some reason.
