IP

IP refers to the Ingress Protection of a luminaire. The first number indicates the level of protection the luminaire provides against the ingress of solid foreign bodies. The second number indicates the level of protection the luminaire provides against the ingress of moisture. IP20 gives protection for normal interior use.

BEAM ANGLE

Please choose the beam angle.

If more exact photometric details are needed please refer to the polar curves or data files.

FINISH

Sometimes there is a choice of reflector finish. Please pick one.

LUMENS/WATTAGE

There are usually a number of lumen outputs to choose from, please specify which one you want.

COLOUR TEMPERATURE

LEDs come in a variety of colour temperatures, those available are shown. LEDs also come in different CRI colour rendering groups. Unless otherwise shown the LEDs are Ra > 80. If a higher specification is required please check for availability.

DRIVER

A driver is needed to operate and control every LED luminaire. They are self-contained units but are wired to the luminaire and have outputs matched to the characteristic of the LED. Its specification depends on whether dimming is required or not. There is also ADDRESSABLE, which is only relevant to DALI addressable fixtures requiring emergency and should be specified with emergency fixtures for that protocol.
