Traditional Comparison (LED vs. HID)
High Intensity Discharge (HID) lights include; Mercury Vapor, Metal Halide,
Ceramic Metal Halide, High Pressure Sodium (HPS), Xenon Short-Arc and
Ultra-High Performance lamps, with HPS being the most common.
Long life – LEDs last up to 50,000 hours (vs. 1000 hrs for Incandescent)
Lower maintenance/replacement costs
Energy efficient – LEDs use up to 50‐90% less energy
Directed light offers better system efficiency
High reliability, safety & durability
LEDs are solid state devices, no moving parts, no glass and no
filaments
No heat or UV in light beam
Environmentally friendly – LEDs contain no mercury.
Longer lifetime creates less environmental waste
Size and digital nature offers new possibilities, never before
