Dear oh dear…
Thanks for the compliments, but the success was very short lived…
I killed the XHP70…
A week ago i killed a XHP50.2
In both cases i nicked the dome and ruined the LED…
:person_facepalming: :weary:
Had this light (Ultrafire V10) waiting for a mod for ages (think it is slightly big for a 16340 light) but yesterday I modded it with lighted tail (lime, orange, red), BG bistro driver (with fix), and Nichia 219B V1 sm453 R9080 led (from the great effort of Clemence et al.) on 16mm Noctigon. The driver floating above the contact plate, lighted ring version with 3x2leds (3x5.9KOhm+5.9kOhm in series with everything).
The lighted tail needs the leds a bit more balanced in output some time, and I had to add the extra 5.9kOhm resistor to restore the user interface, so it is quite dim now (which is ok) and everything works.
The beam has a ring in it from the bezel, but nothing annoying in real life. It throws a good spot, with 450 lumen @30 seconds max (well over 3A current), and the great bistro UI takes care of all other modes. The rosy tint with total absence of yellow is not 100% my cup of tea , but the clarity and colour contrast of this led is sublime!
A very fiddly driver spring bypass, and a rather severe grinding job on the retaining ring to increase the internal diameter:
Wired up my 219C triple…just need to attach the NTC resistor, once the silicone cures, and it’s good to go.
I wasn’t happy with the wire solder job, so I’ve since preheated the pill and resoldered the wires. It looks a bit better now.
Considering it’s my first reflow (using a clothes iron, no less…thanks lampyris!), I’m pretty damn pleased (and rather surprised) that it actually works.
I bought a light off of taobao and modded it. Here’s the work I did: changed out the OP reflector to a dual stage smooth reflector (much like pflexpro’s hybrid reflector) (I had to trim the reflector shorter to fit in the light), mtn 7135+FET driver w/ Bistro, bypassed springs both driver and switch, blue tail light switch, xpl2 v5 4000k led, blue GITD led centering ring, and epoxied a magnet ring on the tail end of the light.
