Ok, here are some thoughts after taking a quick look at this critter...
Paid $35.95, or $39.15 after tax.
Overall I find the package fairly reasonable. The whole setup is comfortable, I wore it for about an hour and pretty much forgot it was there (luckly, the wife had gone to bed!).
The straps are pretty standard fair for regular headlamps, fairly wide, elastic straps with buckle type adjustements. I had no problem adjusting the straps for my head.
The lamp assembly is hinged, like that on the Aurora. I actually find it works better on the Yukon since it is easier to grab and adjust.
The light switch is click-on-led, click-off, click-on-mainbeam. It's not what I'd prefer (I would rather two buttons, one mode and one on-off), but it's liveable.
Turning the bezel adjusts the beam. As in other PT products, the bezel has a slightly rubbery, non slip surface that is pleasant.
The wire bulkheads are very well done with the wire bulkhead into the battery compartment simply being massive. Wire management in general is nice and doesn't get in the way.
The battery compartment has a fairly sturdy latch that has a very postive engagement. There is (as expected, this being a PT product) gasket around the battery compartment to keep the water out. It looks good for heavy rain and dropping it in water, but it doesn't look good enough for serious underwater use (not that it's intended for that kind of use).
The reflector is dimpled (see photos).
Ok, Ok, the beams.
Well, the low beam (three LEDs) is much wider (maybe the reflector helps) and a fair bit brighter than a Newbeam I had lying about (battery state unknown). The downside is it is quite blue. The beamshot doesn't get the colors quite right. The beam isn't quite as blue as it looks and the newbeam isn't as white as it actually is.
The high beam on narrow focus reminds me of a UL 2L. Medium beam quality, fairly tight and similar brightness to a 2L. I did a beamshow with the M2 LOLA and while the Yukon is in the neighborhood, the M2 is still a fair amount brighter. A reasonable beam for the price range I think.
On (max) wide focus, it reminds me of a Maglight. Not consistaint. The main area of usefullness is at the ranges near full spot. I'm not sure the focusability of the light is particuarly useful, but they probably needed it for the feature list.
I didn't try lithium batteries. Hopefully they won't cause problems. The instruction book says alkalines work best, but don't say not to use lithiums. In fact, while they don't say it, they suggest you can use lithiums:
"NOTE - Some battery formulations can emit hydrogen gas. This gas can create an exposion potential in sealed devices if not vented or removed. Your light is equipped with a platinum catalyst that will remove this gas."
The bezel unscrews, exposing the inards. The reflector just pulls out. It is supported by a spring which gives it the focusabilty. While I did unscrew the exposed screws, it didn't seem to come appart - it looks like the housing is glued together. I didn't look close, but it looks like a bi-pin, probably non-standard pin width. The bezel seals with the main unit with a single, fairly small O ring. Pretty much in line with the gasket on the battery compartment.
There is a lot of room in this housing, and it looks like it might make a good mod housing if we can get past the glue issue.
I think they did a good job on this light. It looks to have a lot of utility and is built well for a reasonable cost. It would have been nice if they didn't glue the lamp assembly together and I'd prefer a second switch, but that's about it. I wouldn't mind having a second O ring and a heavier duty gasket, but I suspect I'm getting carried away.
Good job PT!
