In reply to MGC:
Thanks for the feedback on the headtorches - All of our lights have adjustable outputs:
Viper/Indigo - white only with Full power - 50% - 25% - Flashing along with smaller LEDs only in white to conserve battery when you don't need full beam!
Gamma and Manta have different colours and different brightness settings. The colours came from a necessity of needing them for a number of reasons.
Red - for night vision, hunters, fishermen and star gazers
Green - Pilots, boats and also when looking at an OS map without losing your night vision, as when you use red the contours disappear
Blue - Paramedics, as you can see fluid much easier
Flashing red - SOS emergencies and just conserving battery life.
Loom forward to hearing stories of adventures with the lights,
Jay
