Exposure Sirius 11 DayBright Front Light : Gunmetal Black

Season:2026

Brand:Exposure

Code:EXPSIRIUS11DBGMB

Every element of the Sirius 11 has been meticulously engineered to deliver unmatched performance for riders who demand the very best.

The perfect small form front cycling light that crosses the boundaries of ‘to see’ and ‘be seen’ now sits at a beefy 1300 lumens. With a run time ranging from 1 to 130 hours and weighing just 90g - this light is 50% lighter than its closest competitor and is a true lightweight powerhouse that doesn’t compromise on performance or durability. Harnessing 1300 lumens from a Cree XHP35.2 LED, this light delivers exceptional brightness with a precise 8° collimated beam for focused visibility. Combined with the Commuter Lens Cap, it offers 270° side visibility, ensuring you stand out on dark paths or city streets while maximising safety.

For riders who want a minimalist light and a high output, the Sirius DayBright delivers a host of runtime options selected via the OMS (Optimum Mode Selector) and can cater for different rides and conditions. The Sirius hits the sweet spot for power to weight, housed in a super robust CNC machined aluminium body giving the flexibility to be used for the daily commute, longer rides or Gravel forays that drift into the evening.
An IP67 waterproof rating keeps your Sirius performing in all conditions, from heavy rain to unexpected splashes, ensuring reliable illumination no matter the environment.

Featuring Exposure's DayBright pulse pattern, this slick unit lights up the streets both day and night. It can also be helmet mounted with the optional mount, available separately.

New USB-C PD chargingenables one cable convenience and improved charge times by up to 66%. Now with the added benefit of being charged from portable power banks for maximum versatility.

    USB-C

    USB-C PD charging enables one cable convenience and improved charge times by up to 66%. Now with the added benefit of being charged from portable power banks for maximum versatility.

    Optimised Mode Selector

    Various programs in the lights can easily be selected to offer a choice of run times and modes so you can find the right one for your ride, be it an all-night adventure or an intense blast.

    Intelligent Thermal Management

    Patented circuitry within the light will reduce power to the LEDs, if they go beyond the optimum temperature, keeping the light as efficient as possible to maximise output and battery capacity. Once the light has cooled, the power is automatically restored.

    Bespoke pulse pattern designed for daylight use which is more conspicuous than a regular pulse and visible over a kilometre away, even in the brightest conditions. DayBright mode will you noticed. Be Seen be Safe
