The JETBeam Jet III M is a personal favorite light of mine, so I’m kind of surprised at myself for taking so long to make a video of it. Maybe I subconsciously wanted to hoard them all to myself.
The Jet III M has a neat interface. When the head is tightened, you will always have full brightness. When the head is loosened, you have access to a user defined mode with a ridiculous array of options. You can set it to anywhere from 2-240 lumens, strobe frequencies from 1-20 Hz, SOS, beacon flashing, and several other flashing modes. The light is made for rough users in mind, with thick aluminum walls, stainless steel bezels and tail covers, and waterproof seals.
Here’s a video showing the light and how to program it:
