Description The GL bulb filament size and shape combined with the reflector design determine the concentration of a focused beam. The shape of the filament will determine the type of Beam, e.g. a vertical filament bulb will give a circular spot beam, while a horizontal filament will give a slightly oval spot. Lightforce bulbs come in a variety of voltage and wattages, as well as filament types: 12V 20W, 30W, 50W, 75W and 100W plus 24V 50W and 24V 100W for specialist applications. If you in intend to use your light combined with a portable battery pack unit a lower wattage bulb will increase the time in the field. If you have any questions, please feel free to contact us directly with your technical inquiry.
