D1s will be just a different light. Far better thrower, other battery, formfactor, ui.
My D1 arrived from Neal yesterday and I noticed after a few hours that in 1 minute turbo runs the reflector was filled with some smoke. I removed the bezel and lens and made a video of the smoke. I thought it was slowly melting the black centering ring. When I removed the ring it wasn’t smoking. It made a matte area on my reflector. I putted in a white centering ring from my shelf. with the white one I didn’t noticed any smoke. And on the bottom of the black I can see the marks of the MCPCB traces. I sent the video to Neal who showed it to the manufacturer and they said it was water vapor.
I don’t think so.
Anybody else noticed the same with black centering ring?
Well that is definitely not cool. I wonder if there was some kind of laminate or residue on the black ring leftover from manufacturing.
I played with it a day since. A lot run in turbo and the matte thing is gone from reflector. So everything fine with white led gasket. Today I flashed Andúril and played with ramp ceiling and temp stepdown settings.
With 60°C temp and 626 lumens ramp ceiling I made this runtime test:
The test started at ramp ceiling. The head temp doesn’t gone above 41°C and output varied between 100 and 500 lumens most of the time. I will play with it more tonight to get a setup where it can regulate fine the output and don’t get temp on head above 45°C.
I put an sst 40 in my d1 and while i haven’t actually timed it gets hot quick. It is putting out 2250 lumens @30S.
I decided not to go with SST40 in D1. It is hot very fast with stock led and I like the beam. Maybe a try D1S with dedomed SST40 because it can shred heat well as Toykeeper said in her review.
Which one has more throw / candela, SST-40 5000k or XPL HI 5000k? Or is there any noticeable difference? And which one stays cooler longer?
XP-L HI for both questions.
Thanks
If you are running that flashlight without the top cap screwed all the way in, like the video shows, you are likely damaging your light. That snug fit is necessary to keep the mcpcb able to have proper thermal transfer. With out it that extra heat can destroy your light and it’s very likely to do it soon because since there isn’t good heat transfer to the driver the thermal protection features will be way too late, and may never kick in therefore killing your light even faster. It’s really noticeable with the D4 since it pulls so much more current, thus heat. It’s obvious on the D4 because it starts frying very quickly. Hope that helps
