6V MR11-C Halogen Reflector Bulbs for Bike Lights and Flashlights, designed for maximum light and whiteness 
  • Specifically Designed for High Output Cycle Lights and Flashlights with MR11 bulb holders
  • Bright White Light
  • Sealed with a Cover Glass for outdoor use
  • 35mm Diameter (across the cover glass)
  • Choice of 10W and 20W
  • Narrow Central Beam, plus outer flood

To identify bulbs, you may be able to use markings on the old ones.

These MR11-C halogen bulbs are "HOT" high brightness, 10o narrow central beam, especially suited to cycle headlights.  

NB: Narrow central beam MR11-C have proved to be the best for cycling, as wider angles spread the light around, but not sufficiently concentrated to be effective. With a concentrated central beam you can best see obstacles and features ahead, and there is still a wide flood of light, so you don't experience "tunnel vision". 

MR11-C Halogen bulbs are listed below. The interiors are sealed from the elements by a permanently bonded cover glass.

Compatibility: These bulbs are international standard size MR11-C.  Cat Eye and NiteFlux Vision Stick cycle lights use MR11-C bulbs with a thicker cover glass, and may require packing round the bulb rim with our bulbs. The original gasket should preferably be re-used with Cateye. Please bear this in mind if you buy replacements for these brands. Additional packing may be added with foam rubber, such as from draught proofing strip.

ALWAYS REMOVE OR DISCONNECT BATTERIES BEFORE CHANGING THE BULB
Stocks are held in the UK.
