Be careful with this! I believe thereās nothing holding down the mcpcb firmly to the shelf except the stickiness of thermal paste. No additional screws as far as I know so the mcpcb might lose the direct thermal path at some point which could be disastrous.
Yeah magnetic. Also got one without magnet and was sent a D4SV1, which is a much darker shade but perfectly flat and can be set down with a satisfying thunk. I assume magnetic power is the same (uneven to flat surface vs flat to flat) so not a big deal but itās the little things that affect how a product feels
Also, I think I prefer the old style without the rounded edges. Or maybe I just donāt like change
Thatās interesting, I was sent an old D4S cap with mine as the spare tail cap without magnet. The anodising doesnāt match as well as the model, guess old parts are being palmed off which is a bit of a cheek.
Edited to add - Just tested my D4SV2 in green, grey and cyan, all three received since February 2021 and all three have a slight wobble tail standing an a flat plate of glass, all three tail caps are not flat.
Iām a little confused about the difference between the various constant current drivers. Most discussion seems to indicate there are only two versionsā5A and 7.5Aāand that both come straight from the KR4, but D4V2s with this driver have a bunch of components on the back that donāt appear in any photos I can find of the KR4 itself. Is the D4V2 version different from the KR4 version, is this a 5A and 7.5A driver, or what?
Next question: Has anyone disassembled and compared the 5A and 7.5A driver? Is it just a resistor difference or what?
Iād also be interested. I donāt think anyoneās compared them. I notice on my recent D4SV2 W2 that the MCPCB is now white which might indicate that it also uses one of the regulated drivers.
All three of my D4SV2s (W2 / XP-L HI / SST20) have the same white driver board.
Regarding the KR4 driver and the KR4 driver fitted as standard to the cyan D4V2, I own both of these models and didnāt make any request regarding the drivers, mine match the image shown by Bob_McBob. As I did not make any special request regarding the drivers I assume both are the standard 5A and the components fitted to the spring side of the D4V2 version are due to the smaller PCB diameter.
Did i read awhile back that you bought all three of your D4sā in the last couple months? I only ask because my two d4sā i bought last month also have the white driver, but the D4s i bought July 2020 had a red driver. I donāt know if that matters, but i did notice it when my two new ones arrived (W2 and sst20 4000k).
I hadnāt considered the different diameter, and it makes sense components would have to be relocated to fit. So at the very least there are separate D4V2 and KR4 versions of the driver, which can be customized in either 5A or 7.5A. What Iād really like to know is whether itās just something like a resistor change I can play around with later. I canāt find any photos of the business side of this driver.
That is correct, all ordered and received in the last two months, interesting.
One observation which differs from a typical KR4, all three have stable moonlight mode which is set to ramp level 1 by default whereas the KR4 is set at 3.
yes, i had definitely noticed that! i actually started a small thread about the low modes a few months back, in which TK responded to me. She said it had to do with the kr4 driver having a courser low ramp mode due to the amount of power channels, which at the time i did not understand.

Hank - or anyone - do we have any specifications on the UV mules? And are there any special considerations (other than eye safety) to take into account when using the light? Or do or the normal drivers/thermal step down look after the UV ledās as normal?
btw, my sister in law just bought a house in some rocky granite country and we went looking for scorpions with the i5UV olight - wow, LOTS of scorpions!! Most around the 40 - 50mm size (black rock scorpions I think) and they just look like glowing toys under the UV. Our Australian species are generally small and not dangerous to humans although they evidently can give a painful sting.
