That is real beauty! I ordered one… Everything here but glass lenses
So why not swapp plastic to glass lens?
I think it is turbo hard to find glass one that will work on place of plastic one… Yes it may fit but focal difference… I would not like any overfocus or defocus(black hole ) issues. So finding that is also Sizifus job
I was able to find all kind of stuff and flashlights but I can’t believe that I can’t find the one I need with mentioned criteria: Zoomie(budget smaller one) but with anodized threads, glass lens, 25.4mm body, 1×18650 bat, without any gimmick charging ports if possible…
I have purchased a couple of lights from this seller JKK70 Manta Ray C8.2 all pretty good in my opinion. But yes it is also listed a 15 watts, 7 amps x 3 volts = 21 watts. Who knows, really only one way to find out.
I am kinda new here and I have been wondering why someone has not attacked the voltage on these low voltage emitters this way. Limiting the output voltage and increasing the amperage.
To increase the amperage going to the LED, you need to up the voltage to the LED by a bit.
Be careful though. Up the current too much(even if the LED can handle it), but gets too hot, and you might end up in a situation of a runaway with an LED, in which it kills itself.
Isn’t an issue with regulated drivers, but can be an issue with FET drivers.
Those look sharp. Too bad that switch retaining ring appears to be pressed in. I’m curious is the charging circuit is on the same board as the main driver components or a separate one.
Have anyone found a 18650 big reflector thrower as Supwildfire was? I was searching around Ali and nothing interesting there. I would make a mod with Osram white flat or SST40 dedomed version from Kaidomain.
All that’s in the head is two resistors and a diode, antiparallel to the LED. (The diode is necessary for the TC charger.)
This is the tail driver:
Just a reverse clicky on the other side.
I don’t know what to make of this. It’s a nicely constructed light (paid 13€ for it), beefy body, 5.5mm thick LED shelf, the TC charger is nice & clean & watertight, - but the driver is an overengineered solution to a non-existent problem. And it’s not good at what it does.
The TC charger could be done with a standard driver, all it needs is that extra diode.
(Oh and there’s plenty of space in the head, it can fit a 22mm driver.)
Another one for the ‘project’ bin….
Any good suggestions ? Biscotti?
Sounds a lot like the 4×AAA LuxPro I got. Just a contact board in the head, 2 sm chip-resistors acting as a ballast, and the driver in the tailcap. Hell if I can get it apart, though. Got real ring-pullers, not just pointy tweezers, and I’m cranking it cw and ccw and it ain’t budging. No visible threads to see if it’s got rh/lh threads.
Really nice feather-touch switch, though, so while I suspect it wouldn’t function long as a power-switch, even with puny AAAs.
Should fit a Li cell nicely if I ever do get the tailcap apart, though.
