Dear Matt,
I have read about changing my Christmas lights to LED. Is it really worth the cost?

Switching to LED holiday lights does impact usage, and ultimately savings. Keep in mind, holiday lighting is seasonal and your savings really depends on how much you decorate and how many lights you hang.

A typical decorator may put out 10 strings of lights, and perhaps a couple of outdoor decorations (think garland or wreaths). Incandescent lights (using the formula shown at right) would equal about 600 kWh for the season or approximately $10 per month. A switch to LED lights drops that to 100 kWh for the season and is only about $1.50 per month. The savings are visible, but perhaps not worth replacing working incandescent lights. Consider waiting to upgrade from incandescents to LEDs when you are ready to purchase new lights to replace old ones. 

If you prefer lining your roof, yard, home and trees with lights or you decorate with several outdoor decorations, the energy formula is going to look different for you. This type of lighting usually equals around 6,000 kWh, or about $100 per month. Switching to LED would only cost about $15 per month. More than enough savings to justify making the switch now. 

If you would like to calculate your own usage, try this formula to calculate your seasonal holiday usage:
