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*. Your bulbs will provide you with quality light that comes on instantly: an LED bulb takes less than a second to turn on. Warning: these bulbs are electrical category products, so be careful not to leave them within the reach of children.
