The Phase 550 is our lightweight, yet durable, rechargeable bike light for a midweek evening blast on the bike.

  • 5 lighting modes and a 200m beam distance

  • Rechargeable Li-ion battery, with USB-C 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 550 is the final tool you need to make the most of evening rides. With 550 lumens and >200m beam distance, a Phase bike light will keep you company and confident on your dusk rides.

The Phase 550 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 550 has a maximum battery life of 8 hours 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 550 is compatible with a handlebar mount (included), a cockpit mount and a helmet mount. It also conveniently charges with a versatile USB-C cable.

Sustainability and Product Care

Product care information

Lithium-ion batteries do drain over time so make sure your light is charged before use. Avoid using fast charge power supply as this may cause overcharging. The Phase charges best with a 5V/2.0A micro USB input. Wipe clean after use and store fully charged in a cool, dry place. Don't machine wash, that would be daft.

We have dedicated Repair Stations in our stores and we're fully equipped to breathe new life into your old kit. This includes spare parts, patches, new zips and wash and reproofing of your down and waterproofs. Pop into any store or contact us online for more info.
