PIAA's advanced Reflector Facing Technology (RFT) features an exclusive computer-designed, multi-surface reflector that concentrates and focuses the beam pattern of the rearward-facing LED bulbs more precisely than forward facing LED lamps. This allows for more light output per-watt than the competition, while maintaining the low power draw advantages over traditional halogen and forward-facing LED lamps. The result: more concentrated light exactly where you need it.
