This smart-looking device is Nukeproof's all-new Reactor light. In common with Exposure's recently-announced Diablo, the Reactor uses a Seoul P7 emitter, a deeply cunning device that combines four LEDs on a single chip. That gives plenty of output and efficiency, although it's a tricky proposition optically - it's hard to tell how well Nukeproof has coped with that from pictures, we'll have to wait and see. The package includes a choice of lenses to suit your needs.

It all looks good on paper, though, with a claimed 900 lumen output for a healthy four hours with the big-battery Extreme package - there's also an Eco package with a dinky two-cell battery that'll do you for two hours. Both packs are Li-ion units.

There's the usual array of power settings, with the slightly unusual choice of different kinds of high-visibility flashing modes. You also get a low-battery indicator, giving you a chance to switch down to a low-power mode to get home.

Nukeproof Reactor lights are available through Hotlines UK and dealers thereof.
