That's the Nova BULL emergency-vehicle strobe, around 120 lumens. It has a variety of modes, some of them very "ballistic" as you'd expect for its target market. In the videos I posted earlier, one shows it running quad-flash, the other shows it on double-blink. I'm not sure they're still being made, but the Whelen TIR-3 is an equivalent. I got unsolicited praise and questions about the Nova from motorists. They said they liked how I was easy to notice from long distances.

These days, similar power is available from the DiNotte line and the Cygolite Hotshot, and NiteRider's Solas will probably be another good contender in the sub-$50 market. The Solas has the rippled beam-spreader optic like the Cherry Bomb, which should cover a wider arc than the Hotshot as long as it's aimed level.
