Our review

This year’s model isn’t as bright and there are niggling issues, but still well priced for a usable, long life lamp

Nukeproof’s Reactor Extreme is a solid unit with some decent features, although our sample was down on power compared to last year.

The single P7 emitter comes with three diffusers for different beam spreads, from a medium focused spot to a wide spread flood. We had to take a plumber’s wrench to the bezel on our new sample to loosen it enough to switch the caps the first time, though.

Lux ratings are significantly lower than last year’s model, although maximum power run times are significantly up, so it’s swings and roundabouts.

The four-cell battery is awkward to fit to some frames, and the battery alert on our sample only came on less than two minutes before shutdown. It runs for ages – nearly five hours on full power – before that though, and if weight/bulk is a concern there’s a two-cell Eco option that costs £50 less.

The head unit slides off the bar shoe so you don’t need to reset the angle every ride, while an extension lead and Euro plug are included in the big presentation tin it comes in. Stonking online deals enhance its current value too.
