Never heard of them, but noticed they are located fairly close to me in Wyoming.
i have two of their previous models. both purchased from REI over a year ago. IIRC, they are the models PrimeLite 'T' and PrimeLite 'A' (a model that i never owned was the top-of-the-line 'AR', for adventure racing had a hand/wrist/finger [??? i forget which] mounted remote-control for changing modes without having to press a button on the head/light-generating-unit of the headlamp; it was otherwise, IIRC, identical to the 'A' model).
'A' model has 3xAA in a rear mounted battery compartment which can be unclipped from the band and stowed in a pocket or inside of jacket in cold weather. the long battery cable was designed to wind neatly around a part of the battery box when the battery box was clipped to the rear of the headband.
the 'T' model was also 3xAA in a rear mounted battery compartment, but the battery box was permanent affixed to the rear of the headband.
both models had top/bucket strap; both a single 1W Luxeons, plus some 5mm LEDs.
the heads/light-generating-units appeared similar to the current model year's headlamps.
T model also had w/6x5mm white LEDs. modes = 2x5mm, 6x5mm, and 1W HI [no 1W LO] (and maybe a flashing mode - i haven't used these in quite a while and my "old-timers" is actin' up, so i am forgettin').
A model also had 4x5mm white LEDs and 2x5mm red LEDs. mode = 2x5mm red, 4x5mm white HI, and 4x5mm white LO, 1W HI [no 1W LO] (same parenthetical comment as immediately above).
both units were well made; appeared similar in quality to Petzl headlamps; used them for a while with no failures or any type; can't vouch for water resistance.
one really nice feature of both was the fact that, like the PT Apex, the headlamp used TWO buttons to control the headlamp. the buttons were located on the top of the head/light-generating-unit. one button (the right button, IIRC) turned the headlamp ON and OFF (you could do this in any mode that the headlamp was operating in). the other button (the left button, IIRC) cycled through the modes of operation. obviously, having separate ON-OFF and MODE buttons obviated the need for a "timed" OFF as found in other headlamps which only have a single button (i.e., if a button isn't pressed in a certain period of time, e.g. 1.5sec or 2.0 sec, then the next press of the single button turns the headlamp OFF), and, of course, also eliminated the need to cycle through several modes to get to OFF.
light output was similar to other 1W Luxeon LEDs. both were unregulated output in all modes, including the 1W Luxeon.
i thought that they were a fine headlamps and didn't feel as if i wasted my money. i preferred the PrimeLite 'T' model with its 6x5mm white LEDs as not since my military days have i had a need for red lighting, and the 6x5mm LEDs were, of course, brighter than the 4x5mm LEDs found in the PrimeLite 'A' model.
the newest PrimeLite headlamps, with the exception of the top-of-the-line PrimeLite Race model (which i have on order, but haven't rcv'd just yet; nor have i rcv'd a shipping notice yet either) appear to have gone to 3xAAA front-mounted supply. IMO, too bad as this will reduce burntime.
my two shekels. hope this info helps someone who might be interested. i'll try to remember to Post back after i receive the '08 Rebel"-ized" headlamp.
