I will look for some other wire to test with. What part of the holes actually make the connection, do the wires need to touch the bottom of each hole or is the metal around the outside of the holes? It looks like most of the metal is off the SC and V+ holes, so maybe that's my issue.
Uncertain its the sides or in the holes. I just had the tiny wire put in there until i felt resistance. I found it fiddly to be sure, put a wire in, wire pops out, put it back, put in a wire, pops out…etc…
My wires just shoved in…they were “loose ish” so assuming it was more of a connection IN the holes than just from touching the holes.
If I got lucky and every wire touched the sides of the holes and THAT is what made the connection I got lucky then…cuz that wasn’t what I was going for…
I suspect the wires pass through the holes to the chip legs…
When I flash a D4S, I make sure the wires are sticking through the holes, and there is some sideways pressure on them to keep them in contact. I set it up so I don’t have to touch it during the flashing process, to make sure it won’t move and break contact. Then when it’s physically stable, I run the flashing command.
Been testing some cells and found that a Gold Golisi 26650 at 4300mAh capacity yields 19.22A in my D4S equipped with LH351D W6 5000K emitters. This is better than the 15.06A from a Shockli 5500mAh 26650 and a pair of new Sony’s I just received (one cell at a time of course in the D4S), which make 15.46A although they are only 2600mAh cells and considered to be “vintage”.
Use efest instead ? probably better then any golisi or is there something special about them? im gonna use efest or liitokala when i get my grey Warm White - SST20 3000K 95CRI on my way now, very excited to have a warm white d4s tint.
Thanks to Alchemi who sent me the Ledil-Angie 2287 optic for my testing, I tried using the optic on the D4S Nichia 219C and D4S XPL-Hi 5000K, these are the beamshots:
I like the original, but Im digging the slightly smoother 2286 too. 2287 might be too floody for my tastes unless dedicated for indoors. It would be great on a dedicated candle/night D4S.
I have 3 of these D4S (sorry TK) and I just ordered the SST-20 5000k. I love the ability to get the exact amount of light on what I am shining. So far I am very happy with every tint I have gotten, 219c, XP-L HI, and the XP-G2 S4 3D, 4885k.
The 4885k is the rosiest of them all, which is OK but I like white light the best.
Really love the tints of the 219c and the XP-L HI, there great.
Keep them coming Hank, 5000k with high CRI would be great.
