Yeah, that’s the idea…
I burnt some paracord and I placed the washer right in the black fumes to allow a thick coating to depose on it.
My wife hated me for doing that in the living room of course !
I modded my Emisar D4 with 2 1mm^2 and 2 2mm^2 white flats.
These emitters’ voltages make them perfect to put in parallel with each other. Emitters in parallel always have the same forward voltage, so one can predict the relative currents in each emitter by looking at their voltage vs current plots. From djozz’s measurements: if, say, 6A goes through the 2mm^2 LED then 3A will flow through the 1mm^2 one.
It took me a couple tries to get all 4 emitters centered with no shorts. It pulls 19.5A with a VTC5A measured using a clamp meter. I measured 46kcd.
The Cometa takes a standard 17mm driver, so the L4P LD-4A fits without modification
The sweet spot for the 1mm² WF is 4,5A while the 2mm² version should be around 7A.
I’ve swapped a 2mm² in mine 2 days ago and adjusted the current to 6A and get a nice 220kCd and a funny wide screen beam.
Dang man! I never got a Cometa because I already had 3 Jaxman Z1’s, but they take a 22mm driver. I need to find a 22mm driver set at 4.5A with a bleeder for an illumination tail cap. Maybe Led4Power will come out with a larger diameter driver…
From what I see in the published data by luminarium iaculator, CSLPM1.TG maxes at ≈10A. Considering the CSLNM1.TG maxed at ≈5.75A in led4power's tests, for the same relationship the 2mm² could be set at 10A × (4.5 / 5.75) = ≈7.826A.
I have put the 1mm2 on the TX25C2 MTN Electronics 22mm FET driver, and the hotspot is the same size as the Thrunite TN31 but not as bright, it throws a lot. I don’t go over 75% power, when I do it turns pinkish to let me know that it is not liking the current.
The other 1mm2 was put on a Manker U11, made it more throwy, the last one will be put on the Manker T02
