923 CATALOG | legend BEG ELIGIBLE Eligible luminaires under the BEG programme [Federal funding for efficient buildings] have a system luminous efficacy of at least 120 lm/W [140 lm/W for LED strips] and a service life of 50,000 hours at L80 [80 % luminosity]. TOOL-FREE INSTALLATION These luminaires are delivered with pre-assembled components and can be mounted without additional tools. This saves time during installation and enables particularly simple and efficient conversion in the event of renovation or refurbishment. SUITABLE FOR VDU WORKSTATIONS These luminaires meet the requirements of DIN standard EN 12464-1 according to the lighting of indoor workplaces. With a luminance value of L65 < 3000 cd/m2 , the luminaires are standard-compliant for glare-free VDU workstations. PASSABLE Drive-on recessed luminaires are generally used outdoors and can withstand particularly high pressure loads from pedestrians, vehicles and other objects. Drive-in luminaires have an IP protection of at least IP67. POWER SWITCH Luminaires with an integrated power switch can be switched in wattage and operated in several power levels. The power reduction enables flexible adjustment of the light intensity and is usually carried out via a dip switch on the unit. FSC CERTIFIED FSC® ["Forest Stewardship Council®"] is an international certification system. Luminaires with FSC® certification use only wood from sustainable forestry. CONTROLLABLE VIA ... The luminaire can be controlled via one of the following lighting control systems: RF smart [the new control system from DEKO-LIGHT for up to eight light zones], zigbee, DALI, RF [Radio Frequency], Bluetooth, WiFi. THROUGH-WIRING POSSIBLE This luminaire enables through-wiring and can be connected in series with other luminaires. The advantage: luminaires with through-wiring require only one power connection, eliminating the need for costly laying of additional cables. IP PROTECTION The IP protection class indicates the protection of live parts against the ingress of foreign bodies and contact [first digit] and against water [second digit] with two digits. The following applies: The higher the respective digit, the higher the protection. IK IMPACT RESISTANCE The IK value [or IK impact resistance level] indicates how shock and impact resistant a luminaire or certain components of the luminaire are. The following applies: The higher the IK value [IK00 to IK10+], the greater the protection against external mechanical stress. UGR The UGR value indicates how glare-free a luminaire is, thus avoiding disturbing reflections. The lower the UGR value, the more glare-free a luminaire emits its light. Luminaires with a UGR value < 19 are suitable for office environments and workplaces. COLOUR CONSISTENCY SDCM The SDCM value describes the standard deviation of an LED from the target colour location and is a measure of production-related colour differences between LEDs with identical values. The higher the value, the greater the colour deviation. The maximum valid deviation is 6 SDCM. COLOUR RENDERING INDEX RA The colour rendering index Ra describes the measure of the correspondence of the perceived light colour between an existing lighting situation and a reference light source. The higher the Ra value, the better/natural the colour rendering. DIM TO WARM The dim-to-warm function automatically adjusts the light colour when a luminaire is dimmed. The rule is: the lower the luminous intensity, the warmer the light colour. HCL HCL stands for "Human Centric Lighting" and means the tuning of artificial light indoors to natural daylight and the human biorhythm. LIGHT COLOUR SELECTABLE Luminaires with the designation "CCT Dip" can be changed in light colour via a dip switch on the housing and can thus be used particularly flexibly. LIGHT COLOURS / CHANNELS Depending on the LED equipment, different colours can be mixed with the luminaire via the individual RGB / RGBW channels.
