A typical household uses lighting for 2 hours in the AM and 4 hours in the evening. By simply changing your existing light bulbs to the new LED bulbs you will notice an increase in savings while using 75% less energy and provide up to17 years of no maintenance. The normal 65 watt light bulb will have the average life of about 2, 000 hours. While the LED bulb has 50,000 hours of operating time. This equates to burning a light bulb for 24 hours a day, 7 days a week ... that's almost 5 years without ever needing to change the light bulb! Retro fit your existing can light fixtures so you can start using these "green" bulbs today.
