I have had this light for a long time. IIRC since maybe 2010 to 2015. It is a Zebralight (though it has no makings on the outside. The driver board is clearly marked “Zebralight”. The head band is also a Zebra band).
It uses a single CR123A cell (wondering if it can handle an RCR).
Notice the battery tube has no knurling and the head does not have a stainless bezel. The H31 series does have the SS bezel. The switch does have an SS retaining ring. I can take some pics of it if needed.
This is a straight 3 level UI. Not the later one where the levels could be adjusted. It also has no strobe or SOS.
Here are a couple of pics:
I found this in the bottom of a briefcase I used for work. Haven’t seen it in years. Still works fine and CR123A reads 3.2 volts (I always mechanically locked it out).
Any help is appreciated.
