The LED 18W Architectural Design Floodlight from Warehouse-Lighting.com is a powerful but energy-stingy flood light. Although it gives more light than a 150W halogen, it burns just one-seventh of the energy. Like all LEDs, it also has a tremendously long life. Youin. ll only need to relamp this unit once every 12 to 15 years rather than once every six months. Made of rugged, die-cast aluminum, this unit is ideal for isolated or hard-to-reach places.
