I got the DHL delivery from Kaidomain today with my first 3V 50.2’s. They sent 22 in place of the 25 I ordered, although the invoice inside was checked off as 25. Ugh!
I also got the IRA NightWatch 26650 flashlight, with a de-domed SST-40… nice! Like this light, well made and comes with nice accessories including a new lens! Cool!
Got the 3V 50.2’s on an LED4Power board, installed in a pretty tricked out Q8… bypassed large Blue springs, copper plate soldered between springs, solder blobbed 30Q’s, new and freshly charged.
A ridiculous 17,284 lumens at start, falling like a rock to 9,073 lumens at 30 seconds. Need to look into how everything is fitting inside, may need to replace the distance lost by using no centering rings with a piece of copper sheet under the driver.
15,555.6 if I reduce according to the Maukka test lights. Either way, very very bright light.
Well, you knew I would do something like this with the 3v XHP50.2 :))
Cree XHP50.2 3v K2 2A on 16mm Noctigon
Sanded down OP reflector
Cyan GITD tail & LED surround
H17-F driver
Reverse clicky tail switch with tritium vial
Stainless steel body
Copper lined battery tube & head section
Custom made magnetic keyring holder with through switch
I was planning to put one in my Convoy M1, with a FET driver but now maybe my Emisar D1 would be a good host for it.
It has never been a good thrower anyway, topping at only 60kCd even with a Black Flat…
Anyway, three will go in my Amutorch X9 for a sweet hand warmer effect
Thanks CRX. Though I don’t really know what to make up from it. It’s not focused perfectly but nevertheless quite well - and I meant a pure flooder, well out of focus.
I think it should be mixed well…but even if it’s not, a little dc-fix at the flat part of the lens should fix that.
I notice that some lens makers are adding frosting or beads there too.
As an experiment I used a C8+ in desert tan, one of Neven’s LD4A drivers at 9A (fully regulated) and a new Samsung 30Q charged yesterday, and the new XHP-50.2 3V in K2 2A trim. With the driver set up in default modes (and 20ga Turnigy wires with a fat copper alloy spring) it pulls 8.91A at the tail for 103 lumens in Low, 779 lumens in Med, and 2863 lumens in High.
Installed 3v XHP50.2 6000k from kaidomain in my FT02. Replaced driver with 26mm FET+7135 Driver - MTN-26DDm. Draws 14.5 amps at tail switch with 50E battery. I'm afraid to try a hi current battery. Gets pretty hot at 3 min. Thermal control kicks in at about 4 min. It's drawing too many amps for this size light. Not sure if the driver and led can take this power. This is as bright as my XHP70.2 with 5 amp driver.
