Emisar D3AA is available now

@mobiuscorpus, at 3.6A 6V, it should be enough, although I personally consider the NCR18650GA a 2C(7A) cell rather than a 3C cell for cycle life reasons.

So yeah, it should be fine, although if you want less total runtime and longer regulated runtime, something like a Samsung 30Q/Molicell P28A should be right up your alley

If you don’t use turbo much, then the NCR18650GA will be just fine

So is this boost driver for the D4Sv2 the same as the one in the Tint Ramping model? I’m curious if it might be available with a backlit button.

@BlueSwordM

@Mobiuscorpus, actually hold on.

The boost driver has one massive advantage: no matter your battery voltage, it will try and keep output at the highest level possible.
A FET driver will never be able to do that.

That’s a good thing to point out too but I think many people value the pocket-rocket nature of Hank’s lights. Still, I may get one with a boost driver. Still considering.

I don’t know if it’s the same driver, but I just emailed Hank and he said that yes, you can special request the backlit button on the D4Sv2 with the new boost driver. So I did. Also, I don’t know if this is common knowledge, but you can also special order the backlit button on the regular, non boost, non tint ramping driver. I can confirm this because I have one.

Zebralights aren’t just about having a boost driver, but their PID temp regulation is absolutely the best out there, and the lower modes have unmatched efficiency. They are also built to be non serviceable which allows them to be more compact. SC700D remains my favorite flashlight despite its ugly green tint.

Do you guys have any idea how long it takes for the booster driver to appear as an option in d4v2? Or it might not happen at all?

I believe Hank mentioned he had plans for it, but it didn’t seem that prioritized/ it would take some time anyways. Don’t count on a D4 boost driver for the coming months is my best guess…

[tactical_grizzly]

Hank, will your upcoming right angle model be available with a boost driver, or with dual channels?

If he says both, i’m afraid I’ll have to buy two. At least. Dammit!

Basically it’s just the D4V2 right angle model, which will have the exact same configuration as D4V2, including linear dual channel driver, and boost driver options.

Fantastic news!

Hank, the Boost drivers in the quad lights will output 2 amps per LED at the highest setting. What current will the LEDs get at the lowest setting?

Hi Hank,

Will the upcoming right angle head lamp have a threaded retaining ring on the switch or one of the friction fitted rings like on the D4V2?

Many thanks

I am also curious about this. Can the boost drivers go as dim as the linear drivers on level 1?

my experience with the d4sv2 boost driver + b35a, the lowest setting was not low. It was rather high like the dm11 xhp35 HI model.

if it is very similar to the D4v2 model, I wouldn't imagine there is room for a threaded retaining ring. If Hank is staying true to his "as small and powerful as possible" vision with this model.

Oh nooooo :person_facepalming: I totally would have taken that option in my last purchase if I’d known

Thanks for the information though Mob

[Auxilshunter]

New right angle Hank light? Yessssssssssssssssss

Hank, do you have an anticipated timeline for this light reaching the market?

Thanks!

@Hank Wang

KR4 / D4S V2 boost driver (single channel) option is now available.
The boost driver upgrade is available for the quad version of XP-L HI, SST-20, Osram W1/W2, Nichia 219B R9080 versions, each LED receives 2A current. The driver is not compatible with Nichia E21A, Nichia E17A, and mule versions of the flashlight. Please be noted that the boost driver version does not mean higher output than the regular version, it is a more efficient driver(90-95%).

Will this driver be available separately?

[Marvin8]

So if I’m to understand this correctly, the boost driver will cut max output of the D4S by about a third?

[tactical_grizzly]

@FlashPilot

Not sure about D4SV2. The one for KR series will not fit into existing KR4’s according to this Reddit post.

“The boost driver does not work with the original KR4 host unless modified, since it needs more cavity in the head. It’s $18 per one.”

@Marvin8

So if I’m to understand this correctly, the boost driver will cut max output of the D4S by about a third?

Approximately, depending on the LED’s and battery used. 219B’s are an exception and will not see much of a brightness difference at all.

@ArtieT59

my experience with the d4sv2 boost driver + b35a, the lowest setting was not low. It was rather high like the dm11 xhp35 HI model.

Thanks Artie! I hope that does not turn out to be the case for all these new boost drivers. That would be a real shame.

[Marvin8]

I was referring to the W2 hotrod. If so, that sorta takes the hotrod aspect of it away and would be a tough decision for me. Thanks
