Gas Lights (per fixture) Propane Usage
About the Gas Lights (per fixture)
Propane gas lights are decorative outdoor fixtures that produce a warm, flickering flame reminiscent of historic gas lamps. Each fixture burns approximately 2,500 BTU per hour and operates via a small continuously burning flame or an electronic ignition that activates at dusk. Many homeowners install gas lights flanking entryways, along walkways, or at driveway entrances for curb appeal and security lighting. Because gas lights use an open flame rather than electricity, they continue operating during power outages, providing reliable illumination when it is needed most. The 8 hours of daily use represents dusk-to-late-evening operation on a timer or photocell. Some homeowners run gas lights 24 hours a day for constant security presence, which doubles the propane consumption. Each gas light fixture uses approximately 6-10 gallons of propane per month, so homes with multiple fixtures can see meaningful propane consumption from lighting alone.
Annual Propane Consumption Breakdown
The gas lights (per fixture) consumes propane at a rate of 0.03 gallons per hour at its rated capacity of 2,500 BTU per hour (based on the standard energy content of 91,500 BTU per gallon of propane). Running for approximately 8 hours per day over 12 months per year, the total annual consumption is approximately 79.8 gal.
At the national average propane price of $2.50 per gallon, this translates to an annual fuel cost of $199.61, or an average of $16.63 per month. Since the gas lights (per fixture) is not a heating appliance, monthly costs remain relatively consistent throughout the year at approximately $16.63 per month during active use.
The 120-gallon tank is recommended for homes using only the gas lights (per fixture) on propane, requiring approximately 1 fill per year. If you have additional propane appliances, calculate your total consumption using our propane usage calculator to determine the appropriate tank size for your combined needs.

Efficiency Tips for Your Gas Lights (per fixture)
Getting the most efficiency from your gas lights (per fixture) involves proper usage habits and regular maintenance. Ensure the unit is operating at its designed specifications by having it professionally inspected annually. Check gas connections for leaks using a soap and water solution on all fittings. Clean burner ports and orifices to maintain proper flame patterns and complete combustion. An improperly adjusted burner wastes propane and can produce dangerous carbon monoxide.
Usage optimization is the primary way to reduce propane consumption for non-heating appliances. For water heaters, lowering the thermostat to 120 degrees saves 6-10% on water heating costs. Installing low-flow showerheads and faucet aerators reduces hot water demand by up to 25%. For cooking appliances, matching pot size to burner size, using lids to retain heat, and preheating only when necessary all reduce propane consumption while producing the same results.
If your gas lights (per fixture) is more than 10-15 years old, consider replacing it with a newer, higher-efficiency model. Modern propane appliances are significantly more efficient than older designs, and the propane savings can offset the purchase price within a few years. Look for Energy Star certified models that meet or exceed the highest efficiency standards in their category.
