Lighting industry spans industrial LED (factory, warehouse), street, building, medical (surgical) and horticultural (greenhouse LED). Osram (DE, ams Osram), Philips Signify (NL), Trilux (DE) and Zumtobel (AT) lead Europe. LED has largely replaced fluorescent, metal-halide and HID; DALI / KNX smart lighting is rising.

FAQ
Q LED lifespan?
A
L70 (70% lumen maintenance) 50,000-100,000 hours (5-10 years continuous), 5-10x longer than fluorescent, 50x incandescent. Driver power supply (electrolytic capacitors) 30,000-50,000 hours — often fails before the LED.
Q DALI vs KNX smart lighting?
A
DALI (IEC 62386): lighting-specific, twisted pair, 64 devices/channel — simple and economical. KNX: full building (HVAC + lighting + shading), more complex but open ecosystem. Residential → KNX; office buildings → DALI.
Q Horticultural LED spectrum?
A
Red (660 nm flowering/fruiting) + blue (450 nm vegetative growth) + far-red (730 nm morphology). OSRAM Phytofy, Heliospectra (SE) and ams are horticultural specialists.
