My only word of caution on that would be that normal LEDs tend not to work in fog, they just create a luminous mist around you, and you then usually need to switch to the halogen.
I assume that the new LEDs, like on the Myo XP, have solved this problem.
I have the Myo 3, and I'm very pleased with it. Interestingly, Mrs Ridge has a cheapo headtorch that has a much more effective halogen bulb in fog than my expensive headtorch.
