Comments: LIGHTWEIGHT: This is the lightest running headlamp that I've used. I've tried about 3 different head lamps.

BATTERY LIFE: This Princeton Tec Byte headlight takes 2 AAA batteries. I've tried different brands including rechargeable Enloop NiMH batteries. All of them pretty much die off after about 1 hour on the highest setting for me. Therefore, if I'm using this headlamp, I use rechargeable AAA batteries and take them out after each run and recharge them. I would say that this is the "worst" part of owning this headlamp.

BRIGHTNESS: There are two settings on the white light. I almost always use the highest setting. It lights up my running path fine. The amount of light I get on this is quite nice. It has some diffuseness about it that helps with my night-time running. When the batteries are starting to die out, the lamp defaults to a dimmer setting, and it happens pretty suddenly. Sometimes I feel that I get trapped without proper lighting - this could be a problem for some. But I'm usually running with someone else with a headlamp and can run based off of the other person's headlamp.

ADJUSTABILITY: It takes two hands to adjust this one - but this is no big deal. I like it because after adjusting it, it isn't easily un-adjusted by hitting it accidentally with one hand. The light swivels with the axis on the left hand side of the light - unlike some of the other lamps that I have which swivels on the bottom of the light. Because of this the light itself doesn't travel further away from one's head - thus keeping it closer to the body and thus doesn't make it any heavier with it's lever arm going further out. This is a pretty small benefit, but nonetheless I think this is a plus in it's adjustability design when the entire head lamp is this light.

THE BAND: This band is thinner than the other headlights that I own. No problems with it. I wear it with and without a ball cap.

THE RED LIGHT: I don't use this much, but when I compare it to the Black Diamond Spot that I own. The single red light on this little guy is brighter than the two combined on the Black Diamond Spot headlamp. There is no blinking red light that I know of on this lamp. And there is no strobing white light.
