Works as promised. Finally a motion sensing headlamp that I can count on. Also the headband is the most comfortable I have ever used. Worth every penny.
I love the idea of not using batteries. But after a full charge and a night camping and Astro shooting, this thing only last maybe about 2 hours.. or 2.5. Battery could be stronger.
I have had several astro laser pointers. The Radian is by far the best. Top notch build quality, rechargeable battery with a charger, and best of all, lockable for safety. I love it!
This is now one of my most favorite telescope viewing accessories. I had been using a small red light-flashlight when using my telescope. Had to deal with manually turning it off and on while also handling eyepieces, iPad apps, filters, etc., and periodically misplacing it in the dark. This new headlamp eliminates all those problems. The headlamp design frees up my hands to deal with eyepieces, iPad apps, etc. The motion sensing allows you to turn the light off and on with a simple hand wave. The built in memory selects the last lighting mode used (red light) from the multiple options available when you turn it on, which is critical. A terrific purchase for me!
Over the years I have gone through many headlamps. Never have I had one I've been satisfied with, as each has had their quirks. Battery life is great on this! Different color options are available, it's extremely bright, comfortable, and easy to use. Red light is just the right amount for astro usage. Love having the motion detection for using it quickly off and on without having to adjust when hands are full.
This head lamp has many options with yellow, red and white colors. There is a red blinking light, possibly for bike riding. There is also a setting for motion detection to turn lights on and off with the wave of your hand. The band is adjustable and very comfortable to wear and the light angle can be adjusted. This lamp is worth every penny I paid for it!
