Lightforce has meticulously chosen bulbs for their lights, guaranteeing optimum performance and lasting quality. This is achieved by precisely measuring and verifying the efficiency of watts being converted into *candlepower. When paired with the exceptional Lightforce reflector, this creates the renowned light output that has made Lightforce a household name.

For those interested in technical details, the size and shape of the bulb filament, along with the reflector design, determine the intensity of the focused beam. Depending on the shape of the filament, a vertical filament (VF) bulb produces a circular spot beam, while a horizontal filament (HF) creates a slightly oval spot.
