I used cheap solder paste(mechanic) we mostly use here. But very little(applied with needle syringe) Also best performance somewhere at 5.8-6A I could not define correctly as other guys with better equipment. I just have uni-t clamp meter and lux meter for testing purposes.
And I am definitive not getting any angry blue at even more than 7A after more then 3 minutes on samsung INR 30Q.
But that maybe also depends on used rig. Mine was in dd mode with fet driver, single 18650.
But I think that Djozz test also represents well how this emitter work. Some may get higher peak and some lower depends how they will reflow or cherry pick something.
Remember Kawi, the XSword is only making 370 lumens (for over 2 hours!) but still puts light on a water tower 1.9 miles away. Don’t get to “focused” on the low lumens numbers.
But old XP-G2 S4 2B also deserves to be in that graph cause it has just slightly lower lux performance(and sometimes certain g2s42b can have even better performance than certain black flat).
Sorry about those promises but new osram leds came to me and I had to process bunch of orders etc., always something unexpected appears and limits my time for other stuff.
I will not predict release dates anymore, products will just appear on web,maybe that's better.
Please do it soon. I have been waiting since you announced the Luxeon MZ LEDs months ago. There is nothing that’s compareable to your “complete system”.
Some more checks on the BLF D80 with KW CSLNM1-TG led. (Should this led get a dedicated thread btw?)
First, I was not happy with the quite random centering that twisting a 3535 centerpiece provides, so I modded the centerpiece: with a scalpel I cut new corners 45 degrees from the original corners, fixing the 3030-sized led much better. So the flashlight has two centerpieces, one locked around the other, both sanded very thin at the underside for exact focus, now also exact centered.
With the led perfectly centered in 3 dimensions the beam was superb.
Now I measured throw again, first on the almost full 30Q (4.08V): 140 kcd (as I measured before), then let the light run for half an hour (it got hot, I estimate 70 degrees! A biscotti driver has no thermal stepdown, and a 3.9 amp flashlight produces some 15W of heat), the battery was now 3.59 V, so wel over half empty. Measured throw again and still got 125 kcd.
I did the same test with the same battery on a C8 with dedomed XP-G2 S4 2B. Started at 4.08 V with 141 kcd, and with the cell at 3.59 V I measured 90 kcd.
So the low voltage combined with the much needed current regulation of the biscotti driver makes the output and throw of a flashlight with the new Osram led more constant than a light with a direct driven S4 2B.
Plus the current is a bit lower for the same throw.
