Abstract: An angled germicidal lamp is used to illuminate a coil and drain pan for optimum energy utilization. In one embodiment, a variable angled mount is used for positioning a germicidal lamp at a desired angle at the time of installation. In a second embodiment, a fixed angled mount is used for installation where the desired angle of mounting is known prior to installation. The angled germicidal lamp may be used with any coil installation, including flat, tilted and A-coils. For A-coil installations, a preformed delta plate is provided to ease installation.
