Christmas Lights: LED versus Standard Bulbs

When you're decorating your house this holiday season, take into consideration how much energy your decorative lights consume.

Traditional CF7 bulbs use 6 watts per bulb, so a strand of 50 uses 300 watts.  Let's say you use 300 bulbs on your exterior.  Using simple math, at let's say 9 cents per kilowatt hour, six hours per day, for 40 days, that comes to almost $39 in energy over the holiday season.

LED bulbs use 4 watts per 50 light strand.  The same math yields just over 50 cents, using LED bulbs.

In addition, LED bulbs, while more expensive,  last much, much longer, burn cooler (safer). and go on sale at most stores on December 26th.

That's a savings of up to $38 a year.
