You dont have to break it. The top band will slide out?
The band slide out, but it looks odd and I dont need the top band bcs the light sits very tight with the full silicone surface on my head
Configure the headband like this
or let it be through the lights holders as well, so the lights sits tighter
Received one 2 days ago. Feels very good for the price. Light, nice tint & flood, simple UI.
I have an H51C I tried to put it in that band and it's a bit tight (needs to hands to rotate the light), but maybe it would loosen up? I guess I need to check the diameter of the battery tube when I get home. The fasttech one looks nice if it will fit.
My H03 vs foam. Foam lost 
LOL TIR optics are fun for that
Even my Olight S1 can do that, always a cool trick to show to friends 
Does anyone know whatās the longest 18650 the H03 accommodates? Just ordered the headlamp and wonder if my Keeppower 3400s at 69mm will fit. Thanks.

I use protected ncr bās in mine with no problem. H03 has 2 springs (+ and - side of the battery) so I guess it can take
any size of 18650 batteries.
my panny 18650B fit well with 70.2mm
I measured the light and there would fit up to 71mm long cells
KeepPower 3400 fit
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 canāt seem to figure it outā¦ :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 oneā¦. None of the bands have silicone or extra loops onā¦ā¦
Thanks
Hey mate they all loop into one another if that makes sense i will try and take pics.
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.
Thanks for this pic, I didnāt get one like it! I think I can figure it out now,cheers :partying_face:
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.
Sorry but I could not find this info: Do high ampere cell increase output power for this light? Does this light even have FET ?
Worth buying extra 30Q for this if I have for example NCR18650B ?
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 youāre 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.
Ordered mine about a week ago. Paid for USA Express shipping and insurance. Came out to $35.84. Hopefully, Iāll receive it next week.
Itās a great light with great features and a super low price. Itās just unbelievableā¦
Iāll let you know how I like it compared to my expensive headlamps from Armytek and Zebralight. True, you canāt beat the price.
