[Review] Convoy M21H (Getian 3V 8A Green LED)

Review of the Convoy M21H flashlight/torch with Getian 3V 8A colour LEDs. This is available with either red, green, or blue LEDs (green version tested). This is the brightest single colour flashlight I have tested.

You could check this out ;D MK37 TIR lens Long Throw Flashlight - Mankerlight Official I think this is the brightest green led used by manufacturers and no one else used it.

The review points out that the Osram green emitters (the one Manker uses) are not monochrome, being phosphor-converted. It would be interesting to see which one is more efficacious between the Getian and the CULPM green, as they have similar LES and footprint.

I wouldn’t be surprised if the CULPM green could give the Getian GT a run for it’s money. It is a shame the CULPM isn’t available in F1 version, as I much prefer the PC/full spectrum green for night photography.
