  • 800 Lumen at 17mph.

    Not sure how useful that is for riding off road in the dark.

  • Sine wave seems better but eye wateringly expensive. https://www.sjscycles.co.uk/lighting/sinewave-cycles-beacon-hub-dynamo-headlight-black/

    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, 750 lumens at 13 MPH.
  • I use one and yes it's not ideal when climbing or starting out after a long rest as the capacitors take a second or 5 to get full and fully pass their charge on the the lamp. Still pretty great but ideally pair with a battery head torch, which is probably best practice anyway for off-road.

  • Used mine a bunch off road in the dark and it was fine. Did plenty of overnight rides, winter evening laps at the local trails, couple of Bearbones events etc. Good or bad conditions, never found myself wanting more light.

    As with battery lights, pair dyno light with a helmet mounted light for anything fast/technical/lots of low branches (so you can point light where you want to go) or you're trying to open farm gates/negotiate styles etc.
