Yes, this combination works for both KR4 and D4S V2.
There are dozons of different combinations.
We choose the suitable current for each combination.
For example, if you choose 219B on both channels, we will use 5A for each channels.
If you choose 219B on one channel, and W1 LED on the other channel, we will use 5A for 219B, and 9A for W1 LED channel.
If you have your preference, just drop us an email, we will customs make it for you.
Thank you Hank. That is very helpful information. I am just waiting for DM11 to become available before I make my next order for at least two more flashlights. :)
Hank, I’m wondering about ordering a D4SV2 with the new constant current driver but with 4 identical emitters (no tint ramping). In this configuration, will the maximum output be lower than the standard D4SV2 with the same emitters?
Hank can you use a 7.5A noFET driver to power the 219BT-V1 diodes in the D4S V2 flashlight?
The question is about the D4S V2 in the two channel “channel ramping” version (2× 219B 2700K 7.5A and 2x XP-L HI 4000K 9A).
5A for two 219B diodes is a very delicate current. I would prefer 7.5A.
7.5A / 2 = 3.75A per diode
One 219BT-V1 diode can operate stably up to 4A. http://i.imgur.com/bkodESs.jpg
Another question is about the flashlight in a different configuration:
More and more people want to buy an Emisar D4Sv2 flashlight with four Osram W1 LEDs with a single channel driver with full stabilization and with an unlocked FET for Turbo as it is in the KR4 flashlight (9A Constant Current + Direct Drive). Hank are you able to prepare such a driver for D4S V2?
I see that user “CollectEverything” is also asking for the same configuration.
The D4SV2 with 4 Osram W1 LEDs is offered with an outdated driver (FET+ 3). I think many people would gladly buy a D4Sv2 flashlight with 4 Osram W1, W2 or XPL HI diodes if it had a driver like the KR4 has (9A CC + DD), because such a driver would give very good high brightness stabilization.
Hi,
I’m planning to order D4v2. Is there a samsung leds options for this flashlight via sugestions?
(If yes, any post or information about it such as numbers of flashlights max and continuous outputs.)
I’ve been holding out for a 21700 single emitter w/ Anduril2 and - most importantly - a buck/boost driver for so long. I have a D4v2 (5A driver) but never use it because it can’t sustain the output I need. Was about to give up again and order a ZL SC700d. (And/or a KR1 and mod it with theFreeman’s or Loneocean’s drivers.) Can’t wait to order a DM11.
I know it would be absurdly heavy, but I’d get it in brass black. I’d actually get a K1 in brass black if it would take the DM11 driver. I’d have to lug it around for miles in the desert but it’s worth it for copper/brass.
Anyway, can we request the DM11’s driver in the K1? Will the D4V2 or KR1 get the new buck drivers?
