Kaidomain Custom P35
3 volts domeless 6500K or 4000K 80cri.
There is also Custom P70 which is domeless 6-volts.
After little digging I found from Kaidomains own descriptions that P35’s are Chinese SFS80 leds. I ordered few 80 cri versions in 4000K. They give usable current range between 3 and 8 amps. Might be good led for warmer tinted semithrower. Light emitting area seems to be somewhere from 2mmx2mm to 2,5mmx2,5mm.
