Switch Lighting’s new LED replacement bulb creates a self-cooling environment inside, allowing maximum brightness with fewer LEDs. The cooling system allows the bulbs to be used in any orientation with no compromise to their 20,000 hour life (10-15 years). Based on a 75 watt-equivalent bulb used in a home for 5 hours a day, Switch has calculated energy savings of up to $140.00 per bulb over its lifetime. The Switch LED bulbs use 85% less energy than incandescent bulbs and unlike compact fluorescents, they do not contain mercury.
