Not entirely sure these belong in this thread - But i just received the "P70" 6500k (6volt i believe), and the "P35" 4000k 80CRI (3volt !) from kaidoman.com :)) here are a couple quick pics, still figuring out which lights i want to throw these in. Bth of them are domeless HI versions.
Thinking a Emisar D1 for the p35 4000k (i have a couple D1 now and have been looking for a led to put in one). and thinking the Convoy M21e for the P70. Any thoughts?
*EDIT: its "too bad" (my own fault) I just sold my acebeam e70 xhp70 version, would've liked to seen this P70 in that little guy!
P35 4000K’s seem to be quite fragile. I have one in Convoy S2+ with 5A driver and it works fine. I tried to build Convoy thrower with 8A driver and I burned two of them. During reflow the phosphor has started to bubble few times and then it peels off. Now I know that you have to be extra careful with them.
It’s best to test with a power supply the threshold of any LED. Had a surprise with CULPM1.TG from Yinding. Angry blue at 8 Amps, toned it down to about 6 ½ A.
Yeah, I thought I didn’t even push it hard with 8A. That is what Kaidomain’s specs said it should withstand. Seems like at least the 4000K version doesn’t.
thanks for info guys. i will be careful reflowing. i had major issues with (2) xpl-hi 2850k while reflowing recently, that one seems fragile, more so than any other xpl-hi I've reflowed, unless it was a bad batch (bought a couple months ago from Hank).
-> major issues where the top layer delaminating from the base. never saw that before, i didn't heat up hotplate anymore than normal. It sucked. The white base seemed weak and chipped too.
I wouldnt try putting 8amps through a 3535 led anyway, unless i knew it was capable, but since i know nothing about the P35 i will keep it around 6a, thanks for that info!
Think im gong to try it in a m21c, 6amp driver
Apologies Dave1010, didn't even notice it said (sfs80) in the P35 description...
I have to go to bed, so truth be known, it's the SFH55, really the only thing it could be from that list.
Plan is it to mount it in a WT90, should be an easy swap, and with 3 30T's powering it, should be able to get some decent output out of it. Also can compare the throw with a SBT90.2 driven hard.
On Taobao, Pioneman sells it with a 26800 or 26980 tube. They don’t sell 26800 batteries but they sell a 26980 with a claimed 40-60A continuous discharge, 90A max discharge, and 6000 mAh…. should I?
Really great flashlight imo. The only complaints I have would be an additional low mode, and the color temp is pretty cool. Oddly seems to look very white on the target, but out on the water the mist between the light and the target has a slight purple tinge. If the light was 5000k it would be my most used flashlight.
Actually I got the Valkyrie w/SFN55.2 in, along with the SFH55 LED mentioned above. I'll post a teardown review on the light. So far I like the beam also, the numbers I measured did slightly better than Nick's review here, but in the ballpark. I have the NI04 Nightstalker already with a SBT90.2, so should do some comparisons. The lights are just about the same, except the Valkyrie has an OP reflector, the NI04 has SMO. Looked at swapping in the SMO, but its height is less and has a bigger hole so may need some tweaking.
