Exposure Sirius Mk5
The Exposure Sirius Mk 5 is a high power front bicycle light that makes British hand machined lighting expertise more accessibly priced.
The lamp's 550 lumen output is designed for urban use in that it will definitely get you seen without blinding oncoming traffic. Although it would be underpowered as a solo mountain bike light, it will light your way when you take the odd shortcut along unlit towpaths.
The lamps 2,900 mAh rechargeable battery offers variable burn times from 2 hours at 550 lumens to 36 hours at 30 lumens. As is the Exposure way, the battery is self-contained inside the lamp's case. Every Exposure battery is fit for around 1,000 charges and is then replaceable.
Optimum Mode Selector
OMS makes it easy to select how long a burn time you need for the ride and adjusts the power output to that level. OMS therefore helps ensure an optimal balance of run time and output.
The fuel gauge changes colour from green to amber to red to make it easy to keep an eye on the battery's charge status.
USB cable rechargeable
Supplied with USB cable charger. Charge time: 3 hours.
Hand made in the UK
Everything about this lamp exudes Exposure's trademark CNC-machined quality. You can tell by the fact that this is the fifth generation version of this lamp that the Sirius is one highly evolved bicycle light.
Supplied with handlebar mount. Helmet mount available as optional extra.
Intelligent Thermal Management
Patented circuitry protects the LED from overheating so neither the lamp's output nor its longevity is compromised.
