How much does the porch light cost?

Save on outdoor lighting

Winter is coming and it’s getting dark at night. We know that some of you have turned on your porch lights with no plan to turn them off until March. Everyone likes a bright outdoor light, but do you know how much they cost to operate?

Porch Light_webJust one 75-watt incandescent bulb left on 24/7 is adding $11 to your monthly electric bill. If you have more than one light on all the time, you’ll have to do some additional math.

Why not consider these options:

These work with natural light – turning on and off automatically at dusk and dawn. Save even more by swapping out that incandescent bulb with an LED (make sure your photocell works with LEDs.) At a cost of about $10 to $15 for a photocell, you’ll recoup your investment before the winter is over.

Motion Sensors
These are activated by motion as well as daylight. They are more efficient than photocells, but they’re also pricier, ranging from about $30 to $75. Some of these fixtures have timer features as well.

If you just aren’t motivated to put in a photocell or motion sensor, consider replacing one 75-watt incandescent bulb with a 10-watt LED. Even with the cost of the LED (average $15), you still stand to save $30 over the course of the winter.

NOTE: LEDs typically function well outside in our subzero temperatures. CFLs do not.
