Starting to spec out a few components for a light, a lantern-style light.
I want a dimmer capable light, with 360 degrees output. Right now I am thinking about using some of the little domed LED (something like these) and drive them all off of a single QLITE REV.A. (I really want them to work with moonlight mode, hence the driver).
probably will try to mount the little LED’s on a suitable sized copper pipe…. I know round/flat not great for heat dissipation, but will have to work on that, maybe flat spot the pipe. This would work as I will be working it into a lantern style light.
Power it off of a 18650, possible a few in parallel (I know that’s not great, balance issues)
Not sure how many LED’s, probably at least 4, TBD based on light output, I know the board is limited to about 3amps, and the LEDs are about 450ma each… so call it a max of 6 LED.
Thoughts on this setup? I definitely want a nice warm LED, and since I want 360 degree output, I am looking at multiple emitters.
Steel_1024 those pictures are so sharp! The driver looks almost unreal, CGI-like. That optic is about the clearest and cleanest I have seen, even with my own eyes.
Lumenzilla now that’s something new, reflow by flame
Since I don’t have a workbench at the moment, mods have been placed on hold. I did get to spend some time last night rebuilding my brother-in-law’s UniqueFire HS-802 though… His was an original I had purchased for him, back when it was a current-model light. I have a newer one I had purchased for myself that I have previously modded with a 2.2A Qlite and a XP-E2 Torch emitter with fantastic results.
Unfortunately, in the case of my brother-in-law’s light, the process didn’t go so well. I was finally able to brute-force break the glue on the battery tube using a crescent wrench and heavy strap-wrench to remove the head making repairs/mods easier. I’m not sure if the reflector design has changed, or if due to something else, but I wasn’t able to get the XP-E2 emitter to focus correctly. I tried repeatedly with different centering rings, spacers, and insulators, but was never able to get a proper hotspot. Ultimately, I ended up simply removing the original EZ-1000 XR-E and replacing with one of my spare EZ-900 XR-E emitters, and swapping the original 1A driver with a 1400mA Nanjg 101 AK. Kind of disappointing, but at least it is brighter than the original configuration.
What you guys think is the maximum wattage to be dissipated on a 105C/D style stacked driver (not potted)? I’m currently building a triple 219C R9050 EE X6, have 16 AMC7135 installed on a 105D driver (running BLF-A6). With the low forward voltage of these 219C’s I have a feeling that’s a bit much power to dissipate at the driver, about 5.8 W in the worst case (fully charged high drain 18650).
Well with a FET the excess voltage gets burned in the LEDs, right? Maybe the driver will stay a lot cooler, but the 219C’s will run nuclear in no time.
