I have and reviewed the D4/Xiozhi/X-Power light.
That’s what I mod for Nichia triple. You can find the spacer measurements I talked about on previous pages but once again minimum is 2.5-3mm spacer and maximum is 15.5mm.
The threads don’t go far enough without using extra glass or something. So you do need a spacer below the MCPCB. I use copper that I have.
Don’t buy from fancyflashlight as their tails have too high button cap/boot what ever it’s called the green silicone button. And the PCB of the switch is too small. But you should be fine from FastTech or elsewhere.
The light is in parts so ask away if you need some measurements.
I have Carclo 10507, the narrow clear and alu MCPCB for testing before Noctigon arrives.
I used protected and buttoned battery and Nanjg 105c for measuring.
I did cut, sand and polished the pill so it can take 20mm boards or a 20mm spacer instead of 16mm.
Having tools, this is not hard to do, people might like it, but then again, you need tools to make things like this. Well equipped garage or some shop especially if cutting it shorter.
1 piece ok but doing 100 pieces is a little different.
And the total price does add up, $10 host, $3 MCPCB, ~$15 for emitters, lens, o-rings if they need to be added or changed, $3 driver + soldering if you want more output which it can’t dissipate though (2A is enough heat for this size of light), cables, …
Material, cutting, other work, …
$30-35 in material easily as you said + work
I like the D4 and am looking forward to using it again instead of UF C20. Triple Nichia 219, still thinking of direct drive to avoid the 0.1V drop on AMC7135s. Can always limit the output by PWM modes.
