I wanted a light-weight headlamp for jogging at night that could clip onto the brim of a baseball cap. This 125 LU model takes 2AAA batteries and weights approx 45 grams. The cover for the battery compartment can be a little tight and hard to remove, but I found using the rounded end of a big paper clip popped the cover off very easily. The light has a wide horizontal beam pattern. The tint is Cool White. I like the fact that the light has basic UI; High to Low to off. No red and no flashing. The metal clip is very stiff and I needed two hands to be able to slip it onto the brim of a cap. The tilting is limited at 60 degrees, but good enough for walking or jogging in the dark where you need to be able to see your next step. There are no click-stops on the tilting but the friction is good enough to hold the head in place so far. One problem I found is when I tilted the light downward. There is no hood or flap to keep the LEDs from being visible to your eyes. It makes for a very annoying glare. This is not the case if you have the light angled farther forward, but if you angle it too low, it will shine into your eyes.

Runtime was listed 4 hours on High. With a pair of brand named Alkaline batteries, I found it was closer to 2 hours and then the brightness dimmed to about 40 LU for the next 2 hours. The brightness continued to dim after that. I found the runtime was fine, since my night jogs usually last about an hour anyway.

If the clip were not as stiff, the tilting had click-stops and the light did not shine into my eyes when angled down too far, this light would receive 5-Stars.

I also bought and reviewed clip-on headlamps from Klarus and Nite Ize.
