There’s a new version of the FourSevens Preon lights. Although I dislike the new version of the Quark, the new Preons are an improvement over the old version in almost every way.
Personally, I think the old version looked more graceful. Also, you can currently buy replacement bodies, switches, etc for the old model so it’s possible to convert a P1 to a P2 or vise-versa. www.foursevens.com/products/accessories/Preon&list=
And I still wish that a reputable manufacturer would offer a light that uses a 10440 battery! (Since you might not know, a 10440 is a rechargeable lithium-ion battery that’s a similar size to a traditional AAA battery. They deliver 4.2V instead of 1.5V like a traditional disposable batteries, allowing even higher outputs).
