Itās less uneven than it looks in the first pic. Thereās still a bit of phosphor between the top two dies, and between the left twoā¦ so it lights up and looks white in the picture, which makes it look like thereās more space between the dies.
Itās definitely better than other SST-20 lights Iāve tried. It could probably stand to have more of the 3000K + 6500K emitters and fewer 4000K + 5000K though. Farther apart should help pull the Duv down more.
But then: 5000K and 6500K are low CRI. Maybe it would be better with just 3000K and 4000K mix as a base with few 6500K emitters to make it cooler and rosier?
No. At ~4200K, I find itās already about as warm as I can deal with. If I made it warmer, it would look even less white. Even at 100 CRI, it would still look worse. Warm incandescent-style lights make my eyes hurt, literally.
Iāll enjoy my medium-CRI neutral white instead, thanks.
I did not mean to lower the total CCT. Rather - use 6500K exclusively as the cooling agent rather than the mix of 5000K and 6500K. It should arrive at about the same CCT with fewer low-CRI LEDs.
I view it like: mix 4000K and 6500K only, with a good majority of 4000K. If thatās not rosy enough, replace some 4000K with a mix of 3000K and 6500K.
Added a volt meter to my VC2S cause the dial sucks, problem is I think it never stops charging now so I may need to add a momentary switch. Idk anything about electronics so donāt replicate this terrible idea.
Keep in mind, though, that those meters are powered by the voltage source theyāre sensing. That means that ācharging currentā will quite possibly never go low enough for the charging-IC to sense, āOkay, time to stopā¦ā.
The charger will or at least should hold it in CV mode at ~4.20V, and not overcharge, but it just wonāt ever show it as being topped off.
I put a 3v XHP50.2 in my convoy l2 (single cell) with the intention to make it more of a single cell Q8, didnāt work. still throws like a beast considering what it is. but i do like the slightly larger spot.
Iām not sure if iām just getting used to high lumens (my edc has a ~2200 turbo) but it doesnāt seem that bright. maybe itās the X6 driver? still waiting on a LD-A4
I found a cell which had been discharged to 1.8V. Out of curiosity, I tried charging it. Things went pretty well until it was nearly full, and then it refused to go up above ~4.12V or so. It just kept charging and charging.
Soā¦ that cell is basically dead. It may still be usable for some lightweight purposes, but I drew sad faces all over it to make sure I donāt forget which cell it is.
I found that even with the volt meter it does stop charging. I think the lower resistance batteries terminate quicker and maybe just the smaller protected ones take forever
Put a 3V XHP-50.2 in my TK61, the driver is cranking amperage safe for an XM-L2 so I need to address power level, not sure how to go about making the TK61 do the amperage this emitter is capable ofā¦ as it is itās only doing some 2100 lumens.
Iām trying to install an osram white flat in a GT mini but the screw cutouts of the new 20mm pcb donāt line up. Should I just use thermal paste without screws?
