Houston Luxury Lighting

Christmas Lights Power Consumption

The wall of Christmas lights during this time of year at Walmart, Target, At Home and just about every other store can not be avoided. There are colored lights, clear & white lights, multi-colored lights, warm lights, cool lights, blinky lights, and dancing lights. To top it off the choices are doubled because all of the options above are now in incandescent Christmas Lights and LED.

Well, the choice of colors and flashy bits is purely subjective to ones taste. Where Houston-Luxury-Lighting specializes in is deciphering the myths of incandescent vs. LED bulbs and Christmas lights power consumption. One amazing fact shines bright when comparing the two. Incandescent wattage is 80-90% more than LED wattage. That increases the cost power incandescent bulbs 90 times greater than an LED.

96.8034% greater cost for LED sets.
LED strand is 37.9′ longer
(95.8281% longer)
LED strand is 141% more efficient

Of course the LED always comes with the disclaimer you pay more to save more. However,  it would require two strands of incandescent lights to span the distance of the single strand of LED. Realistically making the buy in cost of the incandescent bulbs $15.98 only 36% less expensive than a single set of the LED Christmas lights.

Now let’s see how efficient the decision to go LED will be and how soon the payoff is delivered.

Energy Cost Comparison reports the national average energy rate for 2014 is 12.41 cents. You can use your electric bill and the links at the end of the article to determine your estimated energy usage for the season. We’ll try to keep this simple as possible and list links below if your interested in some extreme number crunching.

Based on a 5 hour usage per day and an energy rate of ¢12.14

  • 100 Count of Incandescent  lights run approximately $.76 per month
  • 100 Count of LED lights run approximately $.13 per month

Putting it in perspective, a single family home could have 10 strands of lights inside and out and possibly more. Making the cost:

  • 100 Count of Incandescent  lights run approximately $76.00 per month
  • 100 Count of LED lights run approximately $13.00 per month

Ideally, LED is the way to go all season long. Along with the energy saving cost and the dramatic decrease in the cost of LED lights, going LED is the wise choice. Not to mention the 3 year warranty. Now we just have to remember to hold onto the paperwork that long.
