What does it do spread out the weight across a greater surface area or something. That thing literally decrease the quality of the beam quite drastically and was horribly placed. It wasn’t attached in any way and when I unscrew the lens and try to put it back on the protector basically spinning in place as I tried to tighten the lens back into place and makes it impossible to use it, so as I was tightening the lens cap no matter what position I had the black protector in it would be ruined because as I tighter to lid it rotated that thing which was almost hitting the led and scratching it and wouldn’t be centered at all after tightened. Unless I glue it but I’m scared to use the wrong type or too much and ruin the flashlight. Should I glue it or… I honestly feel like that thing protecting it does a poor job or really nothing at all. What do you think the chances of the shorting out happening without it? O and thanks btw. Is there any benefit to using all 8 batteries instead of 4 at a time?

What. You mean trying it without the protector thing?

8 batteries will double the run time and maybe boost the amperage a little bit. (I believe this uses a FET driver)

The purpose of the black thing is to center the reflector over the led. It may also keep the reflector from touching the 2 electrical wires as well. I don’t have this model so I don’t know how close the wires get.

The mcpcb has electrical traces on top of it covered in a thin insulator. If either of these traces touches the reflector you will get a short circuit. It protects against this as well.

If the reflector pushes through the thin insulator and touches the negative trace it will cause the light to turn on full blast and run continuously until you disconnect the battery or it burns up the LED.

If the reflector touches the positive trace it will cause a direct short to the battery causing the batteries to get very hot and possibly vent/out gas.

Both are very bad scenarios. Since the factory centering ring height is hurting your focus, try to find something similar that you can use that is thinner. Maybe a really thin piece of plastic that you can cut out of a package. Something that is thin and tough.

Ok thank you so much for answering my question lol. Funny thing is is that the protective black plastic actually made the reflector less centered. Now that it has fallen out like I said it is much better center and the beam is quite better. It is basically impossible for the reflector to touch the wires when the top us screwed in all the way the thing doesn’t move at all even without the protector in there. And even without the top screwed in the distance from the reflector and the wires is of no concern to me. The white surface that is exposed after I took out the protector seems to be quite tough and durable. The reflector hasn’t made a scratch on the white surface for i would be able to easily noticed it and I looked for one. At least not get. What was scratched was the protector, it came like that. But thank you for the idea you offered me it sound like a wonderful solution. I am honestly not very worried about any of that happening it just seems like the material are tough enough to withstand but I am a worry wort and will probably search out something to put under it to protect it. But if I can’t find anything I will just leave as is and I’m thinking it will be fine. It seemed the black protector causes more trouble than it prevents but I don’t want neither of those things to happen. Honestly the best focus is with the reflector flush with the flashlight body but something thin should do too much damage and would hopefully in the long run protect it from further damage to itself. Tho like I said I’m not that worried. I’m worried about using just any old thing for that purpose tho. Won’t the temperatures in there get quite hot possibly melting something that isn’t somewhat heat resistant? Should I use glue? Maybe the company will send a replacement but then again I kinda like it like this

Some plastics can handle heat better than others. You would have to try it and see if the heat melts it. Not that big a deal if it melts. You might just need to try a different plastic.

A couple other things you could try would be to make the factory black piece thinner or you could actually remove a little bit of metal from the bottom of the reflector.

I would not use glue.

I’ve used paper before and it was fine. (On L6 xhp70.2 pulling 18A) Maybe a thin piece of cardboard would work.

A couple layers of kapton tape would be ideal, but I doubt you have any laying around. You can buy some on Amazon pretty cheap.

High Temperature Kapton Tape, Professional for Protecting CPU, PCB Circuit Board. Something like that. I will let you guys know when I find a safe alternative. Btw this flashlight is an absolute beast. Honestly I don’t even care it’s massive and a ton, that’s what makes it all the cooler. This flashlight is on another level. So glad I stuck with this one. Unfortunate these things are happening to it but it’s kinda helping also. Maybe it’ll work out for the better in the end.

Can we lock the fan circuit,so as to save the battery charge?

What do you mean? The fan runs on its own battery. Do you mean mod it to stay on or off? As far as I know, you don’t have to turn it on.

Yeah the fan had its own 21700, I thought. And, from the graphs I saw, turning on the fan had a barely measurable effect on performance.

Just don’t mess with the fan and you’re fine. Unless you live in Dubai or something.
