19A? More like a gamma thrower… 
It’s less uneven than it looks in the first pic. There’s still a bit of phosphor between the top two dies, and between the left two… so it lights up and looks white in the picture, which makes it look like there’s more space between the dies.
It’s definitely better than other SST-20 lights I’ve 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?
Plus the low CRI ones have quite a bit more output to offset the high CCT. So i’d guess you need less of them to balance it out
No. At ~4200K, I find it’s 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.
I’ll 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 that’s not rosy enough, replace some 4000K with a mix of 3000K and 6500K.
Ah, okay. That makes sense. 
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 don’t replicate this terrible idea.
Keep in mind, though, that those meters are powered by the voltage source they’re sensing. That means that “charging current” will quite possibly never go low enough for the charging-IC to sense, “Okay, time to stop…”.
The charger will or at least should hold it in CV mode at ~4.20V, and not overcharge, but it just won’t ever show it as being topped off.
Yeah that’s the issue I’m seeing. Basically trickle charging hence I will probably add a switch for it
Ideally, it should balance out when its leftover “trickle charge” equals the current-draw of the meter/display.
I put a 3v XHP50.2 in my convoy l2 (single cell) with the intention to make it more of a single cell Q8, didn’t work. still throws like a beast considering what it is. but i do like the slightly larger spot.
I’m not sure if i’m just getting used to high lumens (my edc has a ~2200 turbo) but it doesn’t seem that bright. maybe it’s the X6 driver? still waiting on a LD-A4
Because i have to much time but can not make much physical stuff i am using my head and plan a new case for my old Soundstrem SS10R chassis.
They were in my car many many years ago. Because space was tight they are in a not so optimal case now.
The plan will be to build two chases like this
Each woofer will get a Mivoc AM 80 as amplifier
First data from the programm
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.
So… 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 don’t forget which cell it is.
How did you charge it?
Basically, below 2V, you want to charge the cell as slowly as possible.
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
Braver than me. I throw them out recycle my cells responsibly without charging at that point.
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 of… as it is it’s only doing some 2100 lumens.
Is it this driver…
I’m trying to install an osram white flat in a GT mini but the screw cutouts of the new 20mm pcb don’t line up. Should I just use thermal paste without screws?
