- Particularly energy-efficient light bulb, uses only 4 Watts of electricity ,- Handy lamp with built-in dimming function, making every light dimmable ,- There is no need to change the normal light switch into a dimmer ,- The built-in dimmer is actuated via the normal light switch by quickly switching it on and off: ,- 1 x on: 100% ,- 2 x off/on: 50% ,- 3 x off/on: 10% ,- As many lamps as needed can be switched with one switch ,- If the bulb is switched off for around 5 seconds, it always starts at 100% ,- Delightfully warm colour temperature and good colour reproduction, ideal for use in general and mood lighting ,- Resilient to switching, therefore also suitable for frequent switching on/off, e.g. in staircase lighting ,- High-quality, visually appealing housing for good cooling , ,Note for Consumers: ,The LED bulb should only be used in lights intended for its use. Before changing the light, allow it to cool down completely and switch off the power supply voltage. Damaged lights should be replaced immediately. No liability shall be assumed for damage caused by incorrect use. ,The LED light is designed for operation in open luminaires. The heat generated by the light during operation may be emitted into the surrounding area. The service life prognosis is based on this mode of operation. LED lights can, of course, also be used in enclosed luminaires, however their service life will be reduced by insufficient cooling.
