I also had opportunity to play with this larger 2mm white flat. Test with classic light meter and clamp meter (so test is just for reference before someone with better equipment test it). Full Samsung INR 30 Q. Single cell 18650 light with FET Djozz driver.
4.2V, 13.4A, 930 FC
4.0V, 12.5A, 950 FC
3.9V, 11.4A,1050 FC
3.8V, 10A, 1250 FC
3.7V, 9.20A, 1200 FC
3.6V, 8.20A, 1150 FC
3.4V, 7A , 1100 FC
Somewhere at 8-9A will be just enough…
The most beautiful emitter I ever had in my aspheric light. When searching at night in zoom in mode with aspheric light it looks like wide screen TV 16:9 format
But my conclusion this ain’t emitter for single cell fet drivers but you can put it in if you insist and wanna play. Regulation is must if you don’t wanna live on the edge
Also very robust emitter. It can withstand some serious current draw. Add as thinner layer of solder paste as possible.
As promised, here are the results with pics of my Jetbeam T6 with the OFW…well kindof….I had a super hard time reflowing one of the OFW. I gave up and put a sliced SST-20…So, there are 3 OFW, and 1 SST-20.
On my Lumems tube:
STOCK T6 With XPL’s
Fully charged nitecore protected 2300mah batterys
3,910 lumens
MODDED T6 With 3 OFW and 1 SST-20
Fully charged nitecore protected 2300mah batterys
BY-PASSED springs
2,616 lumens
As far as lux goes, I dont feel fully confident in these #s. It was getting late and simply didnt take the time to do a clean and consistent test. I will retest LUX. But for now, here are my numbers.
Measured at 3 meters:
Stock Acebeam K70
Fully charged and tested Samy Qs
412k
Can you perhaps provide us with some beamshots showing that? So would you actually recommend this rectangular shape LED for hunting/searching aspherics?
Thanks
