It looks fantastic! 2.2 amps keeps it somewhat tame with the heat. What material is that? Looks to be an SS bezel, but the rest I'm not sure of. Probably laum or titanium because of the light weight?
Hi Tom , it’s all aluminium, 2024 in classification on Europe and USA. Just it is polished … 22 Watts is turbo mode and it’s not long, because PI regulator control the overheat, it just about 30 sec , then power is slowly down and stabilizated on the thermal balanse.
P.s. sorry for my bad English
If there is a demand for it I can do it but each led is around 20-30 minutes to finish and shipping costs added all things almost triple the led price. I don’t think anybody will pay that much. If there is a significant demand I can make them.
And almost forgot:
Made another C8+ and an Eagle eye X6 with Osram White flat 1mm2
Did some simple work on a friends Q8, put 4 SST-40’s on a LED4Power quad board made for the Q8, swapped out the MOSFET for a 404, opened up the reflector aperture’s to fit over the entire substrate of the 40’s, replaced the springs with stacked Blue springs… the Q8 now has a nice defined hot spot and does 11,200+ lumens at start on new 30Q’s.
32,600 on my meter Tom, translates to 11,247 lumens. Brand new first time charged 30Q cells. Even if you take off 10% for margin of error, it’s still over 10,000… the numbers are what the numbers are, it’s bright as all get out and Rick will be tickled to death with it.
Koef3 found in a bare N4 led test 2670 max, and I found in a bare led test around 2500 max for the SST-40 (the heat management of my gear is good but not as good as koef3’s). In a real life flashlight build with 1x18650 I got 2200 lm at startup. The latest bin is N5 so if koef3’s number is taken you can get 2850 lumen max out of a bare N5 led. Reflector and lens will normally eat 15% (also expected for a Q8) so if everything is perfect you can get 9700 lumen OTF from a quad.
These numbers are for a calibration close to maukka’s calibration (=as close to reality as we know it). Perhaps Dale and Tom use a different one?
