Does anyone have the d4sv2 with w2 leds? Im wondering about heat. Sst20 already heats up very fast and im hoping w2 is better, but I dont think this is the case.

I do, from Vinh, and it throws like a monster. I haven’t noticed it getting any hotter than my other ds4v2s with SST20’s. But I haven’t paid attention to the heat aspects of the light, so I can’t guarantee that observation. But it’s hell of a thrower, and the beam, though rather narrow, is still wide enough for general use, though not ideal for that purpose.

Thanks for the reply. I think I will go for sst20. Still enough throw for me I think.

SST 20 is excellent; you can’t go wrong with it. Enjoy!

For anyone, who planned to purchase D4S with SST-20 Deep Red, before the restock, it was $54.98 ($49.98 + $5 extra), now it is $64.98 ($54.98 + $10 extra).

I don’t know, if any significant (or less significant, or maybe no) improvement happened in the meantime, but be aware of the change in pricing.

I asked Hank what driver he used for D4Sv2 with Osram W2 and Luminus SST20-DR 660nm. He said the driver was FET+1+3. I was hoping it would be a 9A (+ FET for W2) constant current driver like in the K9.3. IMHO, running four SST20-DR with direct drive could be too much current. These are specified up to 3A per LED, so four of them in parallel would max out at 12A total current already. Using a Golisi S43 or PLB55-A (Keeppower 5.500mAh) battery could deliver way more than 12A. With 9A constant current without FET each LED could be driven safely at 2.25A per LED.

i’m itching to buy an emisar with aux LEDs. i already have a late model D4 V1 (V2 driver, anduril, no aux LEDs). i dig the KR4, but i think it’s probably too redundant with my D4.

so… i’m thinking about getting a D4SV2. a few questions… i assume it is NOT possible to use the KR4 driver as the driver boards are not the same size… and the lights are different enough physically that the D4S needs it’s own unique flash of Anduril?

and i’m going to ask Hank if it’s possible to use the lighted side switch from a D4V2. best thing since sliced bread for finding the thing at night to go to the pisser. LOL!

Do you think the D4Sv2 would be a good host for the 219b sw45k or is the DT8 or D18 better?
