I hope that if Fenix ever makes a headlamp they go with a warm tint as headlamps are used for camping/hunting etc. I would take a warm tint over a few extra lumens. Thinking a warm tint LED like the Husky hi-def headlamp with all the goodness of Fenix regulation. Don't see any reason why a Fenix headlamp using two AA batteries could not have the same output (maybe a bit less for the warmer tint Cree) as my L2D. It would sell very well to outdoors type like me. I see Fenix in few hiking/hunting mags. If they show the Regulated runtimes/warm LED it would sell very well.
So here is the run down:
1. Warm tint LED like the TK20.
2. 2xAA with runtime near (willing for a bit less with warm Cree) L2D.
3. 3 modes, Low Med and Hi. Maybe Tubro but no crazy flashing stuff.
4. Comfort is key. Good headband.
5. Like all Fenix lights must use Lithiums and NiMH.
6. Needs to be waterproof and drop resistant.
7. Regulated like the L2D.
8. Beam like the newer EOS. A good combo of spot and flood.
9. Low 9 lumens, Med 45, Hi 100ish, Turbo maybe 150ish.
10. Will this ever be made? I will take 1/2 of the list.
