The Phase 400 is our lightweight, yet durable, rechargeable bike light for a midweek evening blast on the bike.

  • 5 lighting modes and a 200m beam distance
  • Versatile: can be attached to handlebar, helmet or cockpit mount
  • Rechargeable Li-ion battery, with micro-USB cable

Say hello to our sleek, new bike light range: they’re light, durable and rechargeable (and they say hi back). At just 123g, the Phase 400 is the final tool you need to make the most of evening rides. With 400 lumens and >200m beam distance, a Phase bike light will keep you company and confident on your dusk rides.

The Phase 400 has been made with the roadie in mind: whether you’re on a family ride, a mid-week spin or your daily commute to work, you’re going to need an all-round bike light for the incoming dark evenings. But don’t worry if you end up on a canal path or a gravel track, this rechargeable light will suit you just fine for a short jaunt off-road.

Flick between 5 lighting modes: high, mid, low, SOS and strobe. The Phase 400 has a maximum battery life of 8 hours and 20 minutes in low mode, so in the case of a surprise night-time emergency, you’re sorted. The 80-degree beam angle ensures you can see and be seen.

We’ve added in some nifty features, including memory lighting. The light will remember the most recently used mode and default to it the next time you head out on your bike. The Phase 400 is compatible with a handlebar mount (included), a cockpit mount and a helmet mount. It also conveniently charges with a versatile micro-USB cable.

Care & Environmental Advice

Product Care Information

Ensure to charge the battery before use and test the light before you ride. Battery drain will happen gradually over time. Whilst it is extremely rare, there is a small chance that the light will not accept charge again if you let the battery completely drain. Wipe clean and store in a cool, dry place to extend the life of your Phase 400. And, no, it’s not washing machine safe…

Environmental considerations

This bike light is built to last with a hardwearing case and a non-disposable battery, reducing waste and meaning you can love your product for longer!
