I have one purchased just some months ago (i'm forgetting 2mos, 3mos, 4mos ago??? my "old-timers" is actin' up.) off of what may have been the first production run. As such, it uses a 1W Luxeon and NOT a Cree. An earlier post, mentions Cree's only started in the July Production run. Nice headlamp, but nothing spectacular.
With the 1W Luxeon, it's a nice headlamp, but really quite similar to a couple of the Primus headlamps, both the T and A models (own both). Differences are the two 0.5W LEDs in the Coleman eXponent headlamp vs. the more standard 4x-or-6x5mm white LEDs (depending upon which Primus model) and the 6VDC source vs. the 4.5VDC source in the Primus headlamps. The 6x5mm white LED Primus model doesn't have 2x5mm red LEDs though.
Obviously, i'll need to make another purchase after i'm sure that a Cree is actually installed in it and some Boy Scout or a kid at Church will inherit the barely used Luxeon version.
I have both the Nuwai (and also an eGear version of it) and the Argo HP as well. All are very nice headlamps: small, light, with excellent regulation. Like another has already written, a Cree version would be great: 80Lumens, 30Lumens, and something a lot lower output for task/proximity lighting - definitely no more than 15Lumens (though this is still quite bright and could even be used for some nighttime navigation on trails). Methinks that four output levels are perhaps better (e.g., 80, 40, 20, and 10 Lumens).
