The diffuser with the colors throws light in your face (not your glasses, your face). Next time I'm at the mall I may ask for some black nail polish, and see if I can clean that up.
I noticed that, too. It needs a "rim" around the bottom of the 5mm LEDs like it has below the Lux. I modded mine with a bit of black vinyl electrical tape: cut off an inch and a half or so, folded over one long edge ~1/8" to form the rim, then stuck it to the bottom of the light housing so that the folded rim protrudes forward. When I tested it, though, I found that I now noticed the "tab" of the diffuser glowing; a little more electrical tape on the outside of that tab, trimmed to match the edge, and I don't see the diffused glow at all anymore. The new mod cost dang near nuthin', and since it's made of soft tape, it's unlikely to get knocked off; I'll prolly just need to do it again a year or two from now, if the tape gets torn over time.
Looking at the pictures I thought the light looked weird, but it's really very ergonomic. It's kind of an elegant design, really.
I've found that I can wrap the headband around the light housing, in such a way that it stays put. Very handy for pocket carry. But I was amazed when I plopped it on my dresser next to my Petzl E+Lite in it's case; the Ray-O-Vac with strap stowed was nearly as small and compact and the E+Lite! And cheaper, too, and no button cells to scrounge... anybody wanna buy an E+Lite?
Now if we can just find some phospor coating to put on the blue, or maybe we could blast Rayovac with respectful and ego stroking emails to give us a low level white. I don't mind the blue LED, as atleast it looks cool, but if we could just get another level for the Lux I'd be very happy.
I'd prefer a white 5mm LED in there, too, for reading at night; but oddly enough, the blue LED (with the diffuser) works pretty well for reading. It's definitely better than the red, and I find the white Lux, even with the diffuser, to be too bright, so I guess I can learn to live with the blue!
