Measuring slightly over 1 inch in depth, the Puklight is a compact and lightweight low voltage halogen downlight made for installation in areas with very limited space. The Puklight halogen downlight is offered in lensed and unlensed models. The lensed model is UL listed when used with a plug-in transformer and ETL listed when used with a wire-in transformer. The lensed model is recommended for protection against accidental contact with halogen lamp. The lamp is available in a clear or frosted envelope, 10 watt maximum, and may be easily removed and replaced with a lamping tool provided with each fixture. The Puklight may be recessed, or surface mounted with the addition of a surface collar accessory. The fixture operates on a 12 volt circuit and requires a transformer as a power source in typical installations. It may also be operated in a complete ready-to-install kit which contains 1 to 6 Puklights, surface collar, optional glass lens cover, small lightweight electronic transformer, installation template for recessed mounting, hardware, and instructions for easy installation. Lucifer Lighting Company's Puklight waranty. is conditioned on use of Lucifer supplied transformers, which may be electronic or magnetic. The electronic transformers are compact and lightweight like the fixture and are offered in 60 watt wire-in and plug-in versions.
