Im trying to source parts for a mini mag conversion similar to match's minimag mod.
I want to use 2x 14500 cells and ideally use a 3 mode driver.
Im looking at using a cree XHP50 LED and running it at 1500mA for mode 1 which would give about 1200 lumens, I would like to have mode 2 around half of that at 600 lumens and mode 3 on low at around 200 lumens.
Question is, I would prefer a buck driver, due to more efficiency, but is there any significant advantage?
Reason im asking, is because there are so few buck drivers out there that are 17mm diameter, the MTN-MAXlp HP on mountain electronics looks a good choice, but unfortunatley it has components on the underside of the board, which affects my design. I want one with a flat base that can screw down on the flashlight body and make contact to turn on.
This one here looks a good alternative, but is not a buck converter. Likely it will have a zener diode installed.

I also see there are liner regulated boards available, so these will simply convert excess voltage into heat when regulating, so not very efficient, not to mention more heat generated.
Any other suggestions out there? Ive seen plenty of single mode drivers out there, but thats not much help.
Could I go with a 3V LED instead? Ive been trying to find 3V options, but the 3V LED's im looking at are not as efficient as the 6V XHP50.
TIA
