LED Holiday Lights

LED Holiday LightsIt’s that time of year again – to put up your holiday lights! If you are in the market for a new string of lights, now is a good time to consider replacing your incandescent lights with LED lights. According to PG&E, LED lights are up to 90% more efficient, cooler (less risk of fire) and last longer. Plus, if one light goes out, the string still works. If you switch over to LED lights, you can save an average of $50 over the holiday season on your energy bill (so the new lights quickly pay for themselves). Set lights on a timer to save even more!


Benefits of LEDs
• LEDs reduce energy consumption by as much as 90% compared to traditional incandescent bulbs
• LEDs can produce bright light for up to 20 holiday seasons
• LEDs produce almost no heat, reducing fire potential
• Unlike CFLs, LEDs don’t contain mercury
