Exposure Lights Sirius 11 Front Light

The Exposure Lights Sirius 11 Front Light is a compact, 1300-lumen bike light built for daily riding.

It delivers 1300 measured lumens from a Cree XHP35.2 LED, using a tight 8° collimated beam to send more light further up the road. The Commuter Lens Cap adds 270° side visibility, showing your position from junctions and crossing angles. The IK09 impact-rated body protects internal electronics against heavy knocks. USB-C PD fast charging reduces charge times by up to 66%, and supports power bank charging when travelling or commuting in long blocks.

Battery status uses a clear traffic-light system, seen while riding and checked with one press when the light is off.

Key Features and Benefits:

• Cree XHP35.2 LED 1300 Lumens Output: High-output Cree LED produces 1300 tested lumens with strong power-to-light efficiency. This reveals surface detail at distance, keeps brightness stable as the battery drops, and extends usable light time.
• 8° Collimated Optical Beam: Aligned reflector and optical collimation compress light to an 8° beam angle. This pushes more lumens into your line of sight, improves long-range clarity, reduces wasted spill, and cuts forward glare for road users.
• Commuter Lens Cap 270° Side Visibility: Cut-channel lens optics spread part of the beam into 270° side arcs. This shows your position from almost every side approach, improves crossing safety, and makes speed and direction easier to judge.
• USB-C PD Fast Charging (Up to 66% Faster): Power Delivery negotiates higher safe charging wattage to the battery logic board. This shortens full-charge time by up to 66%, reduces downtime, and restores ride-ready power fast.
• Power Bank USB-C Input Support: PD input circuitry regulates variable external power sources. This enables charging from portable power banks, keeps voltage steady, and supports long multi-day use without wall power.
• Patented Intelligent Thermal Management: Internal sensors track LED temperature against optimal efficiency limits. When heat rises, power draw reduces in small controlled steps to protect cells and LEDs. This maintains efficiency instead of cutting output early, extends burn time, and restores full power automatically when cooled.
• IK09 Impact-Tested Housing: Impact-energy resistance up to 10 joules shields internal LED and USB boards. This prevents damage from drops and strikes, protects battery integrity, and keeps electrical paths safe from shock force.
• IP67 Waterproof + CNC 6063 Aluminium Body: CNC machining creates precise sealed tolerances in 6063 aerospace aluminium, paired with waterproof gaskets. This blocks dust and water to 1m for 30 mins, protects USB-C and LED boards from rain and grit, prevents corrosion points, and maintains output in constant wet use.

Sirius 11 is engineered for riders who want strong light, low weight, wide visibility, and fast charging without fragile parts. The 1300-lumen beam gives clear long-range road detail. Side visibility solves blind-approach angles at crossings. Fast USB-C charging cuts wait times, and power bank support adds portable range. Thermal controls protect efficiency and return full power with no extra steps. Impact and waterproof ratings protect internal electronics from drops, rain, and vibration.

Sirius 11 brings high output, long burn time, and fast charging into a durable daily-use build. It checks fast, charges fast, and runs reliably in all weather. It delivers visibility from the angles that matter.
