The Optronics Opti-Brite Diamond Series LED Interior Lamps are designed for broad interior application flexibility and can be wired to operate manually or use their passive infrared sensors (PIR) to automatically illuminate in the presence of human movement. At just half an inch thick, the surface-mount, hardwired lamps can be installed on ceilings, in compartments, under cabinets, and anywhere else light is needed inside a vehicle. The lamps are also dimmable and able to remember previous intensity settings. They are available in two sizes. The 66-LED model ILL02 measures 13.5" and has an output of 2,000 lm. The 36-LED model ILL03 measures 6.7" and delivers a 1,500 lm output.
