Foursevens used to make the “Prism” — a headband with a 90 degree flashlight diffuser adapter. One would take a flashlight of the correct diameter, attach the Prism to it, and put it into the headband. I still have one and it works reasonably well. It’s not clear to me why it was not a bigger commercial success.

The new hotness in my collection of headlamps is the Nitecore UT27. One-touch access to red, and simulates a “zoomie” by changing levels of the “throw” emitter vs. the “flood” emitter in a coordinated fashion. It’s a rechargeable light with the tradeoffs that come with that. My one dislike is that the lowest white light mode is 55lm — I prefer a true moonlight mode.

No affiliations with any of these.
