AceBeam H50 - 2000 lumens - 18650 x1 OR CR123 x2 OR 16340 x2 - Samsung LH351D LED OR Nichia 219C LED OR Osram KW CSLNM1.TG LED

With three LEDs built into the face of the H50, you've got a very powerful set of beams at your command. Not just that, but you can choose one of three sets of LEDs to use: Samsung, Nichia, or Osram. The LEDs are powered by one 18650 or two CR123s/16340s (batteries sold separately). The beams they shoot change with a long hold of the button on top, and double clicking will change the amount of LEDs on. It starts with all three on and steps down from there before recycling.

The H50 is machined from aerospace-grade aluminum alloy, given HAIII military-grade hard-anodization. This makes it quite durable to falls from 3 feet up, though that should be quite rare while wearing the headband.
