In reply to workblowschunks:
I had a Myo XP. It packed up.
I bought a BD one - don't recall the model, but similar to the XP - one big LED and 4 smaller ones. Really good with a good beam, but quite heavy.
But I just bought a Silva Ninox and think it's brilliant. Tiny: the switch is protected so it won't switch on by accident. Not as bright as the BD one (it was a lot cheaper though).
I bought it for running and it casts a really good pattern. THe BD one was too binary - either too small a spot when covering difficult ground or too diffuse to see the hazards clearly. The Silva one has a decent spot but with a diffused light around that. It's not as goood for long distance illumination though.
Silva's 1000 lumen effort looks to be akin to a searchlight.
