I have a Nite Ize Spotlit carabiner clip-on “beacon” light. It’s now 10 years old. Still works fine. Now Nite Ize is targeting pet owners, for clipping on a collar for night walks. Good idea. It used to come in just red and white options, but apparently you can get it in a variety of colors now (it’s a white LED but with tinted translucent casing). And apparently there’s now a multi-colored LED option, for about double the cost.

The brightness is actually pretty soft, enough to gently illuminate a small room with “moonlight” while still not screwing too badly with night vision. Plus the rugged casing is nicely done—no anodizing to get scratched, no glass to break, no accidental activation. It requires a good firm squeeze to activate. Once on, I think up to 10 secs a 2nd press will activate the rapid blinking mode. If you wait longer the 2nd press simply turns it off. This makes for a great travel light in your carryon bag. It’s bright enough that it’ll help you find bag contents without casting off bright light that might disturb others around you.

The total runtime is 20 hrs, on 2xCR2016. Not bad… but I’m wondering if there might be something else available that is more efficient. Any ideas? Or is this the only light like this of its kind?
