Sorry for the silly question, but can someone show me a pic or a how to of how to actually assemble the headstrap, I just can’t seem to figure it out… :person_facepalming:
I have one long strap and one short strap. I assume the short strap goes over the head, but it has a different clip on each end, and the one clip does not seem to be able to go through the other one…. None of the bands have silicone or extra loops on……
Thanks
I tried this on but the rubber on the forehead crimpled vy the band so I changed the long one fitting. Now each end of the long band fitted to the rubber holders each side. No band go behind the rubber.
To H03 owners, has anybody ever replaced the TIR optic with a different one?
Currently looking at Ledil 16mm x 9.7mm TIR optics and wondering if they will be compatible/fit.
Was hoping to get a tighter beam without going to a reflector.
Not 100%, but pretty sure about the following: The maximum output decreases as your cells start to deplete. This means the full 1200 led lumens you’re only going to get with fairly full 4.2V cell. So if your voltage under load reduces, so does output. Therefore with 30Q you will have the same maximum output as with NCR18650B with full cell, but you will have a higher output for a longer period of time with 30Q than with NCR18650B.
The light has a buck driver for 18650 and 2 CRC123 batteries
but the buck part gets only active when the battery voltage is over 4.5V in normal 18650 mode it has a fairly high voltage drop
The main problem i saw for the turbo mode its timed stepdown and if not a fully charged high drain battery you wont reach 3A
The driver has a small inductor and other parts increase the resistance
On normal protected 18650 it wont even reach the full brightness in Turbo
I modded mine with a Narsil TA driver drawing over 5A on a fresh battery
The light has a DTP star so its running well with DD drivers
I needed to sand down the tube lengh about half a mm to get the o-ring working with standard PCB thickness
the AMCs fins also add a bit of thickness
better order this driver in 2OZ thin Oshpark boards
And several questions…
I’ve read somewhere that H03 are not glued recently, is that right?
Will XHP50.2 fit the optic? If no, are there suggested replacements?
How about driver height?
Any other potential problems?
I’ve seen reports that the newer versions were not glued.
On the head threads there was little glue, I forced it with my hands (unlike unglued Emisar bezel ). But I see glue out of the driver edges…
