Technical Details Design: PAR 16 Burning position: 360 ° Dimmable: Yes Colour temperature: 2900 K Equivalence with incandescent lamp: 25 W Rated life: 1000 hours Optimum ambient temperature: 25 °C Socket: GU 10 Number of switching cycles before premature failure (min.): 4000 Ignition time (max.): 1 seconds Diameter: 55 mm Height: 50 mm Net Weight: 45 grams different dimensions for standard bulb: No Rated power: 18 W Lamp power: 78 mA Start-up time up to 60% of full light output (max.): 1 seconds Rated half-angle: 40 ° Rated peak intensity: 280 cd Operating voltage: 230 V Electric Lamp power factor (min.): 0.95 Premature failure rate: 2 % Weighted energy consumption: 18 kWh/1000h Nominal power consumption: 18 W Mains frequency: 50 Hz Nominal beam angle: 40 ° Colour rendering index RA (min.): 80 Light colour: Warm white Lamp is a replacement for standard bulbs the size: PAR 16 suitable for accent lighting: No Note for consumers When installing recessed lighting in ceiling voids, much of the heat is radiated forward, especially with temperature-sensitive materials (e.g., insulation in ceilings) and installation of transformers in false ceilings. Due to the heat radiation behind the reflector, these materials are protected. Light reflections back hardly occur, which improves the quality of light.
