Solar street lighting charges a battery with a solar panel during the day and runs on that energy at night. No power cable is needed.

Safety glass in LED luminaires is toughened glass: stronger than ordinary glass, and it breaks into small, blunt pieces. Ideal for site lights and street lighting.

3-phase track lighting is a power track with three circuits. This lets you switch groups of spotlights separately, ideal for shops, showrooms and museums.

1-phase track lighting is a power track with a single circuit on which you can position and slide spotlights freely. All spotlights on the track switch together.

A power cord is the cable that connects a lamp or appliance to the socket or a fixed connection. Outdoors, special waterproof cables are required.

You can dim LED with an LED-compatible phase dimmer (triac), with a 1-10V or 0-10V signal, digitally with DALI or wirelessly via smart lighting.

An LED driver converts mains voltage into the right current for the LEDs. A flicker-free driver delivers a very stable current, so the light does not flicker.

Flicker-free LED lighting gives constant light without (invisible) rapid fluctuations. This prevents eye strain, headaches and stroboscopic effects.

Kelvin (K) indicates the colour of light: 2700 to 3000 K is warm white, 4000 K neutral white and 5000 to 6500 K daylight. Each room calls for a different colour temperature.

PMMA is acrylic (Plexiglas): a clear, UV-resistant plastic used for lenses, covers and light guides in LED luminaires.
