When the 40 year re-certification comes around it makes sense to review what new options are available to reduce your electric cost. One of the best ways is to upgrade your outside pole lighting or garage of an LED lighting system. Unless recently upgraded, older buildings use high wattage energy inefficient lamps. Called HID lighting, (high intensity discharge) they consume an inordinate amount of electric.
Lighting technology has evolved over the last 10 years, CFL bulbs have replaced fluorescent lights and incandescent bulbs have all but been eliminated, both by Federal regulations and many manufacturers.
LED lighting is now one of the best and most cost-effective ways to reduce electric, and lower maintenance cost since they use solid state technology. Depending on the existing wattage of outside lights you have, an LED system can quickly pay for itself.
