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.
That is some flashlight capital you have there Mitko, what is the mod? I notice that one reflector has a different finish :nerd_face:
@chouster: you can get the driver dissipate the heat of those 12 chips if you have a plan where it goes. What I do is for each stack connect the large lips of the chips facing the outside of the driver with a generous amount of solder (solder is a pretty good heat conductor!), and let that blob end right where the driver’s ground ring is clamped to the pill/body/retaining ring.
And I think that I remember that 7135 chips have an internal heat management and drop their current if they get too hot. Anybody confirm this?
M22 will be dedomed /w fet driver, the result is like 1700lumens and 90k cds, its some kind of a luxury X6 of some sort, the beam profile is virtualy the same yet the heat disipation/the host is ways better
M2X will be modded the same way, the result is 250k cds
M3X i apply only a modest driver mod( 5.5 amps at the emitter) and i pot/ heatsink the driver, its kind of a fragile one( from experience), several ot those M3X will be XPG2 moded ofc
