Rated 5 out of 5 by from Essential equipment Bought this spur of the moment while in REI buying something else. Checked all of the other headlamps that REI had on display and really liked that this had a multifunction white light plus the red light. The switch was easy to use with good instructions to show the sequence to change the various lights. The red light was key during our camping trip in order to be able to see inside the hammock without making yourself night blind. The tilt feature ensured that I could put the light exactly where I needed it....and without blinding the person I was talking to! Worked beautifully and at a reasonable price. I would highly recommend it.

Rated 5 out of 5 by from Headlights I mainly got this for the red light to keep my night vision but the easy use and comfortable head band has made me a happy customer. I used it on the AT for about 8hrs straight and it has yet to dim

Rated 5 out of 5 by from Great red light settings I've been looking for a great headlamp for less than $30 that doesn't have an annoying mandatory blinking red light setting, and this is it. Most headlamps with red light settings make you cycle through either white lights or blinking red lights, which both ruin the reason that I want to have red lights in the first place (maintain night vision and not annoy camp mates). This one not only has the ability to set the red light so that you can turn it on and off with a single click, but you can also adjust the brightness of the red light easily by holding the button down once it is set to the red light and release when it arrives to the desired brightness. Waterproofing, not just water resistance, sealed the deal for me. Icing on the cake was the user friendly settings to switch to a variable, bright white light for situations where you need to see more detail. Overall, great light with a fantastic red light setting.

Rated 5 out of 5 by from Great for setting up camp after dark. I bought this for an overnight backpacking trip. Very small, light, and bright. My first headlamp and I love it.
