The Sinewave Beacon is one of the brightest dynamo lights on the market.
Its a neat compact package that also includes USB charging output.
It also has a unique feature where you can run power from an external battery pack back into the light for full brightness at low speeds or even when stationary.
INTEGRATED USB CHARGER
- Charge your phone, GPS, or any other USB device directly from the Beacon; no need for a separate charger.
FLEXIBLE POWER OPTIONS
- An external, off-the-shelf USB battery pack can be connected to maintain bright, flicker-free light even when stopped or riding slowly. Any available dynamo power replaces battery power until reaching a speed when all power is provided by the dynamo and the battery is no longer used.
- Lots of light, suitable for any style of riding.
SYMMETRICAL BEAM PATTERN
- Ideal choice for off-road riding.
SUPERIOR BRIGHTNESS AT LOW AND MEDIUM SPEEDS
- Dynamo power is optimized at low-to-medium speeds, reaching 200 lumens at just 5 MPH, 500 lumens at 8 MPH, 650 lumens at 10 MPH, and 750 lumens at 13 MPH.
CHARGER PRIORITY MODE
- Intelligently balances power between light and charger to optimize simultaneous use.
- A supercapacitor, charged while riding, provides about 5 minutes of standlight when stopped.
