The battery (30Q) has nothing to do with the driver, in case of the D1S it's an FET driver. The FET driver will pull all amperage it can get from the battery, i.e. using a high drain cell like Samsung 30Q it will draw far more than 4.0 - 4.5A. The white flat has its peak output at 4.0 - 4.5A. Overdriving it will not necessarily kill it but the output will be lower with the additional side effect of lots of generated heat. What you need for the CSLNM1.TG ("White Flat 1mmĀ²") is a current-regulated driver that limits the current to max. 4.5A. So far, the best driver that works out-of-the-box is Neven's LD-A4 driver.
You still drive the LED at 8A just pulsed, temerature is OK because it averages, but the Auger recombination depends on current and this mainly let the output drop
also focus may be off
So to be fool proofā¦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 builtā¦.?
And some soldering skills
Edit. I understand the stock driver could be used and just use a low amp battery or smaller guage wiresā¦I just want to be as safe as I can
Iām 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. didnāt like the the triple optic one bit, thinking of using them in a triple UTORCH C8F reflector nextā¦.
Ok, guys, I have a few White Flats on the way from Hankā¦ 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 HIā¦ thinking of using this 3P 18650 with the White Flat for mega downrange pencil beam. Any thoughts?
Ok, yeah, this one has a separate negative contact pad for the leads from the driver so itās not the pita the Black is.
Will probably build a PZL driver for itā¦ reversing e-switch 7 modes sounds good to me.
I didnāt get the centering ring but will use his old ones. The FR G10 1/2ā 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 thereās really no need for a centering ring, actually)
If Iām not mistaken, the Seanna optic is capable of focusing a die this size to 1Āŗā¦ should prove interesting. There is a pre-focus TIR in the base with a 6ā Fresnel lens up top. Ledil claims a peak candela value of up to 800Kcd, Iām getting 666Kcd from the HI if I remember correctly.
Ledil says it will do 1196 cd/lm from a Black Flat. At 94% efficiency. 1Āŗ 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 2Āŗ.
PZL driver? People still use those? Refresh my memory please. What does the PZL driver have that more recent drivers lack? I donāt remember it being really special when it came out, but then again, I could have ended the sentence with āI donāt rememberā¦ā and the effect would be the same. :person_facepalming:
Nico, I think the Seanna is a bit difficult to come byā¦ seems they were over $60 even a few years ago.
David, the PZL is a 2 channel driver built with all 7135 chips, so itās easy to set the regulation value within the scope of the White Flat. The reason itās 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 Qliteās. Besides, Iām not peopleā¦.
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, āback thenā 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, āback thenā was yesterday, I still use those drivers all the time, even still have some of the huge 07N02 MOSFETāsā¦
If I recall correctly, Comfychair started all that. I even learned to flip the big 07N02 upside down on a Qlite in those daysā¦
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!
I really donāt want to know exactly how much Iāve spent on driver components, boards, li-ion cells and flashlights. I donāt. But I know itās in excess of (Edit: lets just say itās excessive).
