So to be fool proof…we would need a d1s, a black or white flat led and that current adjustable driver, and we would have a 320k lux light like Hank almost built….?
And some soldering skills
Edit. I understand the stock driver could be used and just use a low amp battery or smaller guage wires…I just want to be as safe as I can
I’m thinking the same. For my single emitter throwers, I have flat black. For my multiple emitters, flat white gave better results.
Anyways, looking forward to the matchup. Keep us posted.
Multi Flat White emitters, how many and were you using a reflector or an optic?
I made a triple FW with a sanded/polished optic, pulling 15amps 2100lms. didn’t like the the triple optic one bit, thinking of using them in a triple UTORCH C8F reflector next….
says driver is 17mm, d1s uses 20mm 
That’s not a problem:

The problem is that as of now l4p driver does not support e-switch. Your Emisar will turn to a twisty.
Ok, guys, I have a few White Flats on the way from Hank… tell me what I have to watch out for. Isolate the MCPCB from ground, limit the emitter to around 4.5A, anything else I should watch for?
I have a D01 Courui that I fitted with a Ledil Seanna quite a while back. It makes over a mile throw with an XP-L HI… thinking of using this 3P 18650 with the White Flat for mega downrange pencil beam. Any thoughts?
Don't think the white flats required the isolation, black flats do. That sounds like a great host to test one out in!
Yeah, the white flats have a neutral thermal pad, IIRC.
Yes, regulated to under 5A, and focus focus focus. The centering piece that Hank has made will help with that.
Ok, yeah, this one has a separate negative contact pad for the leads from the driver so it’s not the pita the Black is. 
Will probably build a PZL driver for it… reversing e-switch 7 modes sounds good to me.
I didn’t get the centering ring but will use his old ones. The FR G10 1/2” thick board my Seanna mounts to is threaded onto the light engine part of the Courui, as such it can be threaded up/down to dial in proper focal length to the Seanna optic. Should work. (with this set up there’s really no need for a centering ring, actually)
If I’m not mistaken, the Seanna optic is capable of focusing a die this size to 1º… should prove interesting. There is a pre-focus TIR in the base with a 6” Fresnel lens up top. Ledil claims a peak candela value of up to 800Kcd, I’m getting 666Kcd from the HI if I remember correctly.
Ledil says it will do 1196 cd/lm from a Black Flat. At 94% efficiency. 1º beam, no estimate on Kcd on the Black Flat. No listing on the White Flat. By contrast, they say the XP-L HI makes 492 cd/lm at 2º.

How much for Seanna optic and where to get them?
I’m tempting
PZL driver? People still use those? Refresh my memory please. What does the PZL driver have that more recent drivers lack? I don’t remember it being really special when it came out, but then again, I could have ended the sentence with “I don’t remember…” and the effect would be the same. :person_facepalming:
Nico, I think the Seanna is a bit difficult to come by… seems they were over $60 even a few years ago.
David, the PZL is a 2 channel driver built with all 7135 chips, so it’s easy to set the regulation value within the scope of the White Flat. The reason it’s called puzzle is that the text indicating the components sits inside the ATTiny pad, so if you put the ATTiny on first the rest of it is a puzzle.
People still use em? Well, with the resurgence of these Osram emitters the need to keep current controlled brings back even the Qlite’s. Besides, I’m not people…. 
Wight’s PZL board…
Just looked at the thread again for the PZL driver. It just reminded me that not only was wight always coming up with the latest and greatest drivers back then, he always stubbornly insisted on his drivers being aesthetically designed as well. Things had to line up, have symmetrical spacing, etc. Every driver was a work of art!
Yeah, “back then” it seemed like I was the guinea pig, I built everything he and MattAus came up with, including a go at the Knucklehead driver. lol
With my memory, “back then” was yesterday, I still use those drivers all the time, even still have some of the huge 07N02 MOSFET’s…
If I recall correctly, Comfychair started all that. I even learned to flip the big 07N02 upside down on a Qlite in those days…
Yep, comfy set the stage, wight wrote it down in traces. The old HD2010 drivers were the inspiration as I recall - pure spring melting, LED desoldering power!
Indeed, and the HD2010’s reflector would exploit that welding class in a hurry…
I really don’t want to know exactly how much I’ve spent on driver components, boards, li-ion cells and flashlights. I don’t. But I know it’s in excess of (Edit: lets just say it’s excessive). 
Speaking of the hateful HD2010, I once took this outside of the box approach to bring the emitter into the reflector for proper focus. That was the light that started me modding, it didn’t work right out of the box and the extended process to get it working and working well taught me a lot… lol
For you David… I don’t think we ever got the Knucklehead working… not for long anyway…
oh, not trying to call you a knucklehead just reminiscing about the drivers those guys came up with… this one was one of Matt’s I think (MattAus)
