The Optronics UCL41 Series Scene Light is designed to deliver an intense white LED beam pattern at a 45-degree angle to its mounting position. Mounting the lamp higher creates a larger scene, while mounting it lower creates as smaller scene. The lamps can be rotated before mounting to deliver light that is oriented to a vehicle's front, rear and sides. This lamp is 8.7" wide, 2.95" high and 1.59" thick when installed, including its mounting plate and bezel. The lenses and housings are made of tough polycarbonate material that is sonically welded, and the base is made of sturdy aluminum. The lamps feature a solid-state, surface-mounted device that protects the electronics from moisture, shock and vibration. The lamps come with a no-hassle, one-diode lifetime warranty protection that will replace the lamp if even one diode fails.
