How Much Does It Cost to Run Holiday Lights?
The energy cost of holiday lighting depends on the bulb type and the hours of operation. Here is the complete comparison.
LED vs. Incandescent Energy Use
A standard 100-light string of incandescent mini-lights: 40 to 50 watts. A comparable 100-light string of LED mini-lights: 4 to 8 watts. Energy reduction: 80 to 90 percent. At the average US residential electricity rate of $0.18 per kWh, running 10 hours per night: Incandescent (50 watts x 10 hours / 1000 kWh x $0.18): $0.09 per night, per string. LED (6 watts x 10 hours / 1000 x $0.18): $0.011 per night, per string. A display with 20 strings: $1.80 per night for incandescent vs. $0.22 per night for LED. Over a 40-day holiday season: $72 vs. $8.64. The energy cost difference between LED and incandescent: substantial over a full season for a large display.
C7 and C9 Comparison
Incandescent C9 bulbs: 7 watts per bulb. LED C9 retrofit bulbs: 0.5 to 1 watt per bulb. For a 60-foot roofline with 60 C9 bulbs at 10 hours per night: Incandescent: 60 x 7 x 10 / 1000 x $0.18 x 40 days = $30.24. LED: 60 x 0.75 x 10 / 1000 x $0.18 x 40 days = $3.24. The LED C9 retrofit option: a one-time investment in retrofit bulbs ($80 to $100 for 50 bulbs) that pays for itself in about four seasons of energy savings, and sooner once the far longer bulb life is counted.
Using a Timer
A simple plug-in timer ($10 to $25): set lights to run 5 to 6 hours per evening (dusk to 11 PM) rather than running all night (10 to 12 hours). Running 6 hours vs. 12 hours: cuts energy cost in half with no change in the display’s appearance when anyone is actually looking at it. Combined with LED lights: reduces holiday lighting energy cost by 90 percent compared to incandescent running all night. (For more on this, see Best Holiday Lighting Brands and Products.)
Working With a Contractor on This Project
Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.
Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.
Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.
Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.
Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.
Making a Confident Decision
The information in this article is designed to help you ask better questions of the professionals you work with, evaluate their answers with more confidence, and understand the decisions involved in this type of home services project. It is not a substitute for professional assessment of your specific home.
Every home is different. Roof slopes, local weather, tree exposure, soil conditions, and existing system condition all affect what the right solution is for your specific situation. The general principles here apply broadly, but a professional who assesses your home in person will give you guidance that accounts for the details that general articles cannot.
When you are ready to move forward, getting at least two or three quotes from licensed, insured, local contractors is the most important practical step. It lets you compare approaches, assess contractor quality, and confirm that the solution proposed matches your specific situation and budget.

| Mid-range display (roofline, trees, pathways) | $700 to $1,500 for the season | |
| Elaborate full-property display | $2,000 to $5,000+ for the season | |
| Takedown-only service (for self-installed displays) | $100 to $400 | |
| DIY material cost (consumer LED lights) | $200 to $500 for a standard display | Annual replacement cost: $50 to $150 as bulbs and strings age. |
| Commercial displays (small retail property) | $1,500 to $4,000 for the season |

Book professional installation in September or October — quality companies fill their schedule before November. Commercial-grade LED products used by professionals last 5 to 10 seasons; consumer retail lights last 1 to 3 seasons on average.

Frequently Asked Questions
LED mini-light string (100 lights, ~6 watts): approximately $0.011 per night at $0.18/kWh, running 10 hours. A 20-string LED display: $0.22 per night, or $8.64 for a 40-day season. Incandescent equivalent: $1.80 per night or $72 per season. For C9 LED retrofit bulbs on a 60-foot roofline: approximately $3.24 for a 40-day season at 10 hours per night.
Yes -- LED holiday lights last 5 to 10 times longer than incandescent (25,000 to 50,000 hours vs. 1,000 to 2,000 hours), use 80 to 90 percent less energy, produce no significant heat (reduced fire risk), and are available in virtually every style that incandescent lights offer. The upfront cost of LED lights: typically 2 to 3 times more than incandescent. The savings in energy and replacement cost: pay back the LED premium within 1 to 2 seasons.
5 to 6 hours per evening (dusk to 11 PM): the most common residential schedule. Use a timer to automate this schedule consistently. All-night operation: wastes energy (no one is viewing the display between midnight and 6 AM in most cases) and increases wear on the light strings. A timer pays for itself in energy savings within a single season.
LED mini-lights (C6 or M5 form): the most energy-efficient string light option. LED C9 retrofit bulbs in a commercial stringer: the most energy-efficient roofline option. Solar-powered holiday string lights: zero electricity cost but limited to well-lit outdoor locations with adequate sunlight for the charging cycle (not effective in many northern winter climates with short daylight hours and low sun angles in December).
A professionally installed LED display (commercial C9 bulbs, 100 linear feet of roofline, 5 trees): approximately 500 to 1,000 watts total draw. At $0.18/kWh running 5 hours per night for 40 days: $18 to $36 in electricity. Professional installations use commercial-grade LED products that are very energy-efficient -- the power cost is a minor component of the season-service price.
