LED Down Lights
The Halogen Down Lights in your home or office or business consume too much power. They pose a fire risk as they generate lot of heat. You can save power consumed by halogen down lights by replacing them with LED down lights. The LED down lights consume only about 20-30% of the power consumed by an equivalent halogen lamp. The LED lamps have a life of about 50,000 hours when compared to about 1200 hours for the Halogen lamp. The following calculations show the savings in replacing a halogen down light with LED down light:
Let us consider the case of replacing a 150 W halogen light with a 30 W down light. Let us assume that the light is on for 12 hours in a day and that the energy cost is 30 cents per unit.
Energy consumed by the halogen light in a day = 150 W x 12 hrs = 1.8 Kwh = 1.8 units
Energy consumed by the LED light in a day = 30W x 12 hrs =0.36kwh = 0.36units
Energy consumed by the halogen light in a year = 1.8 X 365 = 657 units
Energy consumed by the LED light in a year = 0.36 X 365 = 132 units
Energy cost for the halogen light in a year = $197
Energy cost for the LED light in a year = $40
Savings in a year on energy cost = $197 - $40 = $ 157
The cost of replacing the light is recovered in less than an year.
