Chinese LEDs: SFN55.2, SFN60, SFS80, ...

Has anyone access to the datasheets of these interesting LEDs from China? No problem if they are available in Mandarin only, I can handle that. 

Some new flashlight models have appeared on Baidu and Nealsgadgets, using these LEDs. Even though they seem to be available in coldwhite only their ratings look promising.

I’m testing a NI03 with the sfn55.2. It’s a 3 volt led (verified) 7×7 mm domeless. Like the Gtfc40 except with fewer dies and not 12 volts/high cri. So far output is pretty good. Throw looks good too. CW of course.

I’m mainly interested in the output numbers. Also, how is the tint at low and high levels compared to other LEDs?

The tint is very good. No tint shift or chromatic aberrations from the OP reflector. Great throw. Imagine a P2 1A sliced and diced xhp70.2 in an OP reflector. It’s being driven at roughly 29 amps also!

I have the NSX4 with the SFQ60 leds. They are extremely green, more than almost any other flashlight I own. Maybe the new versions have been improved now. The throw and lumens are impressive, though.
