This set of 5 standard bulbs, also called A60 for their 6 cm diameter, will be ideal for replacing your old halogen or incandescent bulbs. Indeed, their E27 screw base will fit perfectly in most luminaires. Moreover, they will allow you to save money while providing you with quality lighting: with a consumption of 9W, they will produce lighting as powerful as that of a 60W incandescent bulb. A lighting also optimized by their 180° lighting angle, allowing a homogeneous lighting of your interiors. Thus, with its 806 lumens (luminous flux defined by the quantity of light generated), they will be ideal for the lighting of your small living rooms, such as your bedrooms and living room, or the ambient lighting of larger rooms. Their so-called neutral white lighting (4000 kelvins), will provide you with lighting as close as possible to daylight. This set of bulbs is also available in warm white (2700 kelvin), for a warm lighting, close to the lighting colour of your old incandescent and halogen bulbs. For more information..: As with all our bulbs, opting for LED technology means choosing light bulbs: Less energy consuming: up to 80% energy savings. Safer: Thanks to its technology, the glass of a LED bulb heats only very slightly. Thus, the risks of burns and fire are greatly reduced, allowing a more diversified use of the bulb (low suspension, bulb on a table lamp without a lampshade, low spotlight, etc.). Moreover, the LED does not produce UV or infrared radiation, and is not composed of any dangerous products (such as mercury for example). Lasting: LED bulbs have a longer life than other technologies. XanLite LED bulbs have a life of 15,000 hours (about 7x longer than a conventional bulb). With better colour rendering: LED technology allows a CRI >80*. Attention: these bulbs are electrical grade products, so make sure you keep them out of the reach of children. *CRI, or Colour Rendering Index, is a value between 1 and 100, which indicates how accurately a light source can reproduce the colour of objects. Daylight is the best light source for color reproduction (CRI=100). The higher the CRI, the brighter and more precise the colours are.
