Nitecore HC33 1800 Lumens High Lumen L-Shaped Headlamp

I'm disappointed it didn't come w/ a battery, apparently there's some fine print I missed when I ordered. I just happened to add a battery to my order for a spare. Headlamp works great, good battery life on that "spare" I ordered. Bonus it works w/ my other brands of 18650 batteries unlike some other brands.

For some reason it will not work with fresh charged 34 or 35 hundred nitecore batteries . Shuts down immediately ? Put another in and works sometimes ?

Ran across an HC33 a few years ago and have loved it ever since. I mistakenly bought batteries for a different headlamp and decided to purchase another headlamp which fit the batteries. This one is even better!
All came in good packaging and on time.

Super nice piece of kit. Solid as a little flash light for everyday use, good brightness and throw for what I need. I like the light without the extras, the magnetic tail and head strap just make it even more useful.

I didn't like the way mine was designed and so over time I tore it down and rebuilt.
The way it comes I had to take the battery out every time I wanted to charge which was every day given that I use it at least a hour a day.
I bought a Rigid headband from Mills Fleetfarm that is intended to be for welding helmets.
I built my new headlamp on the Fleetfarm headband.
I glued the Nitecore battery into the Nitecore charger and then mounted the charger to the side of the Rigid headband , had to solder wires and build a positive post coming out of the led light section , what a pita but in the end I ended up with a nice headlamp system that I can now simply plug in just like you would a cell phone.
Since rebuilding i no longer have to remove the battery every time I want to charge

I don't recommend buying the HC33 unless Nitecore redesigns it.
