For mod based on thеsе flashlights I use 16 mm noctigon mcpcb , but treated with emery paper. So it may be 15.9 or close to it.
Reflector of Xtar h3 have dimensions 19*11mm
Another important characteristic is existence of pwm flickering. I know that broit have low frequency pwm .
Nitecore, Skilhunt, Zl , Armytek have no pwm flickering.
Do you mean the Boruit RJ02? That’s the one model headlight I own. I don’t have any visable pwm. Only on camera does it become visable. Maybe I’m not sensitive to it?
the H03 has a buck driver with significant voltage drop
without spring bypass only a almost full high drain cell gives 3A to the LED
it comes with a DTP star
Output of h03 more than 1000lm. With out hi drain cell.
For H03 there are also high efficiency drivers "buck":http://forum.fonarevka.ru/showthread.php?t=22959 and "boost":http://forum.fonarevka.ru/showthread.php?t=35292
Someone just stole my h30, so I am looking to buy one of these two. Could anyone point me to where I could pick one of these two up for around $30? Thanks.
You’ll have to look/wait for a sale. I think the H03 and hc30 are about $40 on some Aliexpress stores at the moment, but I don’t see anything cheaper.
BTW, stores to watch are Banggood, Gearbest, Fasttech and Aliexpress. I’ve found that if you have an account with them you can put the lights you like on a wishlist/favorite and they will email you whenever those products go on sale. Sometimes it’s an email only sale that only a few will see.
You can also contact MadMax and Freeme to see if they have any coupon codes for the lights you want.
Also, I’ve seen youtube reviewers post coupon codes in the video description area.
