Eco-Led replacement bulbs use state-of-the-art LED (Light Emitting Diode) technology. With their ground-breaking design, Eco-Led bulbs are safer due to the instant start and increased brightness. Because they are shock and vibration resistant, and generate low heat, their lifespan can be extended to over 20.000 hours while consuming only 1/10 of the power of an incandescent bulb.
