Gloworm XSV Replacement Optics - Clear - Spot}, Clear
  • £6.99
  • RRP £7.99
  • Saving you £13

Gloworm XSV Replacement OpticsThe XSV Replacement Optics from Gloworm is a replacement/spare optic that is interchangeable for different light effects and diffusion for Gloworm XSV cycle lights.Genuine replacement optics for your Gloworm XSV Light. Choose from either: Spot, Flood or Wide for the X2/XS G1.0, Spot, Wide or Honeycomb for the X2/XS/XSV G2.0 or Spot/Spot, Spot/Wide or Wide/Wide for the CX/Alpha. SPOT (96% Efficient/FWHM 17 degrees):The spot optic provides the narrowest beam. It is also the most efficient, allowing the greatest light output. It can be used in conjunction with another spot optic to gain the greatest possible output and therefore beam distance. This configuration is best used on the helmet to see down the trail or to spot the exit of a turn. Alternatively, the spot could be paired with another optic type from an alternative light pattern. FLOOD (84% Efficient/FWHM 25 degrees):For a smooth diffused light pattern the Flood optic is the best option. It takes the light and smooths the light across the width of the beam, making it slightly easier on the eye and creating even light from left to right. A pair of Flood optics would provide a wall of smooth light, however in doing so a significant amount of light intensity would be lost compared to a pair of spot optics. The flood is best used in tandem with a spot or wide optic. WIDE (87% Efficient/FWHM 40 degrees):This optic provides a wide rectangular beam, it utilises the light output to provide more peripheral light and less light in the vertical axis. While not as optically efficient as the Spot Optic, it provides very good output for a wide-angle optic. Two wide optics can be paired as a great option for use on the road, however, when paired with either a flood or spot optic an effective hybrid beam can be created. HONEYCOMB (87% Efficient/FWHM 30 degrees):Designed for use with the XSV, the Honeycomb Optic is used to gain a smooth diffused light pattern when used with 2 spot optics or other honeycomb optics. It takes the light and smooths it across the width of the beam, making it slightly easier on the eye and creating a more even transition from the bright beam centre. Features: Gloworm G1.0 The X2 and XS use the same single cone optics, whilst the CX and Alpha share the same double optics. The G1.0 XSV uses the same optics as the G2.0 XSV Gloworm G2.0 The X2 and XS use the same single cone optics The XSV uses the same optics as the G1.0 XSV.Buy Gloworm Accessories from Chain Reaction Cycles, the World's Largest Online Bike Store.
