Namely: opting for LED technology means choosing light bulbs that use less energy: 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.). Another important element is that LEDs do not produce UV or infrared radiation and are not composed of any dangerous products (such as mercury, for example).
