Disclosed herein is a remotely adjustable lighting system with security features. The lighting system includes a lamp (e.g., luminaire) which carries solid-state light sources and a sensor. The solid-state light sources emit visible light at an adjustable output intensity. The sensor is responsive to line-of-sight wireless signals, and the lamp increases and decreases the output intensity of the light sources in response to output signals of the sensor. The lamp provides security features by selectively accepting and rejecting instructions carried by the line-of-sight wireless signals to vary the output intensity of the light sources.
