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.
