A hybrid fixture featuring light-emitting diodes (LEDs) and either an incandescent lamp or a compact fluorescent lamp (CFL), and integrated with an occupancy sensor, addresses both energy and security concerns. The design features a low-wattage, high-brightness LED that runs continuously during the night. The occupancy sensor turns on the main CFL or incandescent lamp only when motion is detected, flooding the area with warm, bright light—enough to light a path or allow a person to unlock a front door. After a few minutes, the occupancy sensor turns off the incandescent lamp, while the LED array continues to run.
