SOLID BRASS - Constructed of solid cast brass for a lifetime of durability, the VOLT Top Dog Scotty Downlight is a heavy-duty low voltage fixture for residential downlighting and moonlighting applications. WATER-TIGHT - A double silicone O-ring keeps water from entering the fixture but in the event of water intrusion, a weep hole in the center of the lens allows it to escape. A silicone plug at the lead wire exit also prevents moisture from entering the fixture through the stem. PROFESSIONAL GRADE - The fully-adjustable glare guard and knuckle make it easy to focus the light with precision. A solid brass locknut and 1-inch strip-resistant threading provide superior mounting stability. A 40-foot 18AWG SPT-1 premium tinned copper lead wire and surface mount are included. LAMP READY - This fixture is designed for use with an MR16 bulb (not included) up to 50W. For the version of this downlight that includes a bulb, please enter B0CH3XFPS7 in the Amazon search bar.
