Barn lights, security lights, yard lights call them what you will, but they are everywhere! Despite their utilitarian style and simplistic performance, they pose a significant opportunity for an upgrade to LED lighting. The Lithonia Lighting BarnGuard LED security light has it all with its white light, high CRI, instant-on, and low energy consumption. Adjustable light output of up to 10,000 lumens and switchable color temperatures are standard features included. BarnGuard LED is easy to install on an existing mast arm or directly to a wall or wooden pole. The included twist-lock photocell provides reliable dusk-to-dawn operation, and the crisp white light keeps sites safe and secure without ever having to change a lamp again.
