BikeRay Ray-Fi front light review
This monster from BikeRay resets the big power/small cost benchmark for lights all over again. At 628g, the big three-LED headlamp and hard plastic cuboid battery aren’t aimed at minimalist 24-hour racers.
With a theoretical 3,000-lumen output throwing a ton of well-spread light down the trail and wrapping round to the peripheral, it’s great for bombing down descents though.
There are four output levels to extend run times, but you’ll get nearly two hours before the warning light comes on even at full power. You even get a wireless control switch for toggling modes.
The O-ring mount means a wrap of tape is needed on shinier bars to stop the big head unit slipping and even then it can waggle on steppy/rocky descents, creating a slight shimmer effect, but it’s not a deal breaker. A helmet mount is supplied too.
Twin straps secure the bulky battery well, as long as you’ve got a vaguely flat surface for it somewhere on your frame and the waterproof connectors get a threaded collar to lock them together.
