The Lumotec IQ-X is the reference 100 lux dynamo headlight — road-shaped beam, standlight, daytime running light and Senso automatic switching. Choose black or silver.

Highlights

  • 100 lux from a 6 V dynamo — one of the brightest StVZO dynamo headlights made
  • Wide, even IQ-X beam with a sharp cut-off: lights the road, not oncoming eyes
  • Daytime running light (DRL) and Senso automatic on/off
  • Standlight keeps you lit at the lights
  • Manual switch; side slits for visibility from the side
  • Aluminium housing, 120 g; output for a wired rear light

Why riders choose the IQ-X

It is the reference dynamo headlight for commuting and touring: 100 lux with a beam pattern engineered for the road rather than a round torch spot, and no batteries to charge or forget. The Senso mode turns it on at dusk and in tunnels; the standlight keeps it lit while you wait at an intersection.

Mounting

Aluminium fork-crown bracket included; handlebar and under-handlebar mounting with the IQ-X mounting band or a handlebar bracket (sold separately). Rear-light output on the back of the lamp.

Dynamo only

Runs from a standard 6 V / 3 W hub dynamo (or sidewall dynamo). It is not an e-bike light and must not be wired to an e-bike's DC lighting output. Pairs with any Shutter Precision, Shimano or SON hub dynamo.

Busch & Müller lighting and mirrors are covered against defects in materials and workmanship. Damage from crashes, water ingress through an unsealed connection, connecting a DC e-bike light to a dynamo (or a dynamo light to an e-bike supply), and normal wear of brackets, straps and mirror glass aren't covered.

For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim with the distributor for you. This cover is in addition to your rights under the Australian Consumer Law.
