FTF

FTF: 20-Watt, 12V Nominal, MR11 Multi-Faceted Dichroic Reflector Quartz Halogen Open-Face Display Bulb, sharing the identical internal multi-mirror geometric dimensions and 12V low-voltage supply tolerances as its companion model framework, but featuring an open-face layout (without a front glass cover plate). It is explicitly engineered for integration inside sealed projector optical barrels and specialized fiber-optic light-guide illuminator boxes requiring unrestricted cool air induction vectors to prevent thermal pocket trapping.
