That os just 4.2A. Far from the led peak performance.

Hank what about 21700/26650 version of D1s with XPL Hi ?

After some more test, we decide not to provide the D1S+ due to the issues below:

1. With the D1S original driver, when you use the 3.6V cell, you can get 320kcd without a doubt.

2. But when to limit the driver current, the driver simply can not give desired 5A current
to the LED, thus the LED is either over-driven more than 5A, or under-driven below 5A.

That is why we are not able to offer D1S+, sorry for the problem and initial hype.
But we will still offer this LED on the Noctigon MCPCB.

Regards,
Hank

Where is the link? You don’t have that updated on your web site.

Hank, can you offer emitter on pcb with center ring.
this is good for modding

Now I know what Ralphie must’ve felt like in “A Christmas Story” when the neighbor’s dogs ruined their Christmas turkey dinner.

“The heavenly aroma still hung in the house. But it was gone, all gone! No turkey! No turkey sandwiches! No turkey salad! No turkey gravy! Turkey Hash! Turkey a la King! Or gallons of turkey soup! Gone, ALL GONE!”

Too bad it sounded like the perfect thrower. Thanks Hank. I know you will come up with something that I will be interested in.

Output for the White Flat seems to be about equal between 4.5A and 5A in the test results from djozz. Above 5A, it starts falling. A 4.2A driver wouldn’t be giving up anything you could see with the naked eye.

I’d love to see a buck driver for the D1S to better support emitters like the White Flat, SST-20, and 219D. I am perhaps less interested than some in hitting the absolute peaks, as I spend more time using my lights with my eyes than with a luxmeter.

Ditto, a Buck driver for all the Emisar models would make them all winners in my book.

No, not far from the peak performance at all actually.
The difference between 4 and 5 Amperes in output numbers is hardly worth overdriving this LED so hard.
You could make it 13 × 7135 though, and get 4.55 Amperes, which is a good compromise.
But i doubt there’s enough room on a single sided driver board for so many 7135’s.
But then again, why not design a dual sided driver board?
This little White Flat has a nice low Vf so it’s suitable for 7135 drivers.

Buck drivers always eat up a little Voltage, they have a minimum voltage drop.
Maybe the same as the old tech 7135 though, which have a minimum voltage drop of 0.15 Volts.
But more expensive and you need more space (hight) for the inductor, especially with high currents.

Hank please use this led in the D4S, it should work with the stock driver and get super results

13 chips would be the hot setup, or 12 380's. I think somewhere there's an 7+1 or 8+1 OSHPark driver, but probably not to accommodate the Attiny85, or have DEL's tweaks to get the 25/45/85 working more reliably. The most important issue is having the 4.7R before all uses of Batt+ -- this was the biggest issue. Of course the FET gate stuff isn't needed with no FET. Pretty sure I've done 2 channel ramping with a 7+1 or 8+1 style driver, as long as you use the Eagle claw 7135's, least for the single.

If the size is the same as the D4, I’ve made a 1+2+5+moon driver with the 85. If you want to upgrade, you could stack the inner 3 7135 chips and get a total of 11 in a 2+4+8 config to get up to 3.8A

Waiting for sub ohm sense resistors here, to stack on LD25 drivers.
Aiming for 4 – 4.5 Amperes.

Hey Hank , stop teasing us, first you get us exited by saying you’ll be making a D7 & then tell us it’s a no go , then this D1s+ which is also not gonna happen. Crying
Please don’t tease us anymore ,in future please keep new developments to yerself until it’s up & ready & gonna be for sale.
This isn’t a negative whine because I highly rate your lights & consider them at the top of the pile & I can’t wait for more new ones but I get so disappointed when I think the next best thing is coming & find out it’s not.

that’s the point of a feeler, it wasn’t a promise. They want to gauge interest and most of us like to get prepared. I don’t mind feelers

I still think he can do it; there are options others have given. Maybe we will see something even better come out of this.

Hank can do it better and way less expensive than a custom modder so I’ll wait to see what happens. I’d also like a D4S with these emitters Smile

Hmm.. The D1S is begging for an LED like the White Flat 1mm², and it would definitely sell.
But the White Flat 1mm² is begging for a current regulated driver, which is not (yet) available for Emisar.
But the trend in LED land is low Vf, so it’s time for Emisar to get a current regulated driver available.
It shouldn’t be that much more expensive than the DD driver i.m.o.
And it will open the door to more choice in emitters, like Nichia 219B V1 for the quads, without risking their lives.
The electrical path can be optimized as far as you wish, and you can use the highest drain cells.
Longer run times in the highest modes without immediately losing output.

Come on Hank, get some proper drivers for your sweet little lights.
I might even buy one !

D7 cancelled. D1S+ cancelled. I conclude Hank Wang only produces quality lights without consumers being guinea pigs. Excellent. Thumbs UpCool

which driver should i use with this led? im thinking about putting is in a c8+ or maybe L2.

It depends on what you want from the driver. If you want the best, most efficient driver, get a L4P driver tuned to the proper current. If you just want it to be “regulated” and have a decent UI, you should get a driver that uses AMC7135 chips for power, PWM for lower modes, and Anduril firmware.
