169 IK CRI IP KEY TO SYMBOLS Protection classes: · Protection class I / Protective conductor Protection class II / Protection by double or reinforced insulation IP protection rating IK impact resistance rating Pivoting capacity in degrees: Luminous flux maintenance Unified Glare Rating: The lower the UGR value, the lower the psychological glare. Through-wiring possible Describes the colour rendering quality of a light source. The higher the CRI value, the more natural and true-to-life the colours appear. Can be installed in insulation. Can be covered with many types of thermal insulation materials. The Multi-Lumen function enables gradual adjustment of the light output, allowing you to tailor the lighting to suit your needs. Multi-Colour describes the ability of a light to produce different light colours. For lights with adjustable Multi-Colour, the light colour can be adjusted using a switch. This is technically achieved by installing multiple LED chips of different colours. By changing the switch status, the proportion of the respective LEDs is adjusted to produce the desired light colour. Fire-retardant: developed and tested for use in certain fire-retardant suspended ceilings. Fire protection application (up to 90 minutes, tested with EN 1365-2:2014‚ Fire resistance tests for load-bearing components – Part 2: Ceilings and roofs‘). Outdoor use and fire protection applications (up to 90 minutes, BS476-20:1987 and BS476-21:1987) Half-diffusion angle: Describes the beam angle in degrees. The smaller the angle, the more concentrated the light will be. Enables wireless control of the light fitting via compatible control systems or mobile devices.
