1.3-in-1 Fixture This versatile low voltage fixture can be used underwater, in a well, or as a well light to illuminate outdoor walkways, driveways, gardens, fountains, small ponds, decks, docks, architectural features, and more. This version features a shielded glare protector that provides directionality and reduces direct glare. Since this is an MR16 fixture, it is larger than the MR11 version. 2. Waterproof A cold forged brass top, which is less porous than cast brass and better suited to waterproof conditions, plus a durable PVC body and a flat glass lens raised to prevent water accumulation. It is waterproof (IP68 rated) and fully submersible in up to 1 meter of water thanks to a waterproof wire gland and pressure-fit gasket (installation tip: tighten in a star pattern), but it can also be used on land or in a well due to its efficient heat dissipation. 3. Bulb Ready Designed and optimized to allow for easy replacement of the MR16 LED bulb (not included), unlike competitor integrated LED fixtures that must be completely replaced after the bulb burns out. 4. Low Voltage Contains a 4 foot 18AWG lead. Like all 12V lamps, this lamp requires a low voltage transformer (not included) to operate.
