How Much Does a Halogen Bulb Cost to Run? (2026 Electricity Data)

Halogen bulbs span a wide wattage range depending on the fixture. A standard A19 halogen draws 43 watts. A mini halogen in a recessed can draws 20 to 50 watts. A PAR flood runs 75 to 150 watts. A torchiere floor lamp draws 300 watts. The math for all of them is the same: watts × hours ÷ 1,000 × your rate. All figures below use the April 2026 U.S. residential average of 18.05¢/kWh from the EIA Electric Power Monthly, running 8 hours a day.

Mini halogen, 20W (accent/display): $0.004/hr, $0.87/month, $10.54/year.

Mini halogen, 35W (recessed can): $0.006/hr, $1.52/month, $18.45/year.

Mini halogen, 50W (recessed flood): $0.009/hr, $2.17/month, $26.35/year.

Standard halogen, 43W (A19, replaces 60W incandescent): $0.008/hr, $1.86/month, $22.66/year.

Halogen flood, 75W (PAR30): $0.014/hr, $3.25/month, $39.53/year.

Halogen flood, 90W (PAR38): $0.016/hr, $3.90/month, $47.44/year.

Halogen flood, 150W (outdoor/security): $0.027/hr, $6.50/month, $79.06/year.

Halogen torchiere, 300W (floor lamp): $0.054/hr, $13.00/month, $158.12/year.

A single 300-watt halogen torchiere costs more per year than many refrigerators. That one fixture type is the biggest electricity cost of any lighting in a home. The full per-appliance wattage reference is in the appliance wattage chart.

Watts measure power draw. Lumens measure light output. A 43-watt halogen produces about 800 lumens. A 9-watt LED produces the same 800 lumens. The LED needs one-fifth the electricity for the same brightness because it wastes far less energy as heat. The DOE Energy Saver estimator uses the same watts-times-hours formula for both bulb types, and the ratio holds across every wattage tier.

At 800 lumens (the standard living-room bulb), a 43-watt halogen costs $22.66 a year at 8 hours a day. A 9-watt LED producing the same 800 lumens costs $4.74. The LED uses 79% less electricity for identical light. Per bulb, per year, the savings are $17.92.

The ratio scales up with wattage. A 75-watt halogen flood ($39.53/year) replaces with an 11-watt LED flood ($5.80/year). A 150-watt halogen outdoor flood ($79.06/year) replaces with a 20-watt LED ($10.54/year). A 300-watt halogen torchiere ($158.12/year) replaces with a 30-watt LED torchiere ($15.81/year). The savings per fixture climb with every wattage step.

State electricity rates spread the annual cost of a single 43-watt halogen bulb (8 hours a day, 125.56 kWh a year) from modest to notable. The April 2026 EIA data puts the range at more than 3x between the cheapest and most expensive states.

Louisiana (12.44¢/kWh): $15.62/year. Texas (~14.8¢/kWh): $18.58/year. National average (18.05¢/kWh): $22.66/year. California (~31¢/kWh): $38.92/year. Hawaii (39.79¢/kWh): $49.97/year.

The 9-watt LED equivalent at the same hours: Louisiana $3.27, Texas $3.89, national $4.74, California $8.15, Hawaii $10.46. The per-bulb savings range from $12.35 in Louisiana to $39.51 in Hawaii. In high-rate states the upgrade case is strongest, but even in the cheapest state each bulb swap saves more than $12 a year. The electricity rates by state guide has the current 2026 rate for every state, and the halogen bulb calculator runs the math at your specific rate and daily hours.

Ten standard 43-watt halogen bulbs averaging 6 hours a day use 941.7 kWh a year and cost $170.00 in electricity at the national rate. Replace all 10 with 9-watt LEDs and the same fixtures use 197.1 kWh and cost $35.57. Annual savings: $134.43.

LED bulbs retail for $2 to $5 each. At $3 per bulb, 10 LEDs cost $30. The electricity savings pay that back in under 3 months. At $5 per bulb ($50 total), the payback is under 5 months. After that, the $134 annual savings is pure return, every year, for the 25,000-hour rated life of the LED.

In California at 31¢/kWh, the same 10 halogen bulbs cost $291.93 a year. The LEDs cost $61.10. Savings: $230.83 a year, with a payback of under 7 weeks at $3 per bulb. In Hawaii at 39.79¢/kWh, savings reach $296.27 a year.

The existing LED vs. incandescent cost comparison covers the general case for any bulb type. The numbers here are specific to the halogen starting point, where the wattage gap is narrower (43 watts vs. 60 for incandescent) but the savings are still 4 to 5 times the LED cost.

1. Replace high-hour fixtures first. A halogen bulb in a kitchen or living room running 8 hours a day saves $17.92 a year when swapped to LED. A closet bulb running 15 minutes a day saves $0.56. Start where the hours are highest. The lamp electricity cost guide breaks down the per-fixture math for table and floor lamps.

2. Kill the torchiere first. A single 300-watt halogen torchiere costs $158.12 a year. That is more than a typical refrigerator. A 30-watt LED torchiere replacement costs $15.81. No other single fixture swap in a home produces a bigger per-unit savings ($142.31 a year).

3. Halogen to LED is a smaller jump than incandescent to LED, but still 5x. A 43-watt halogen is already 28% more efficient than a 60-watt incandescent for the same light. But the LED at 9 watts is still nearly five times cheaper to run than the halogen. The halogen's efficiency edge over incandescent does not close the gap with LED.

A standard 43-watt halogen bulb costs $22.66 a year at 8 hours a day at the 2026 U.S. average rate. A 300-watt halogen torchiere costs $158.12. The 9-watt LED that replaces the standard halogen costs $4.74 a year for the same light. Switching 10 halogen bulbs saves $134 a year and pays for the LEDs in under 3 months.

The halogen bulb calculator handles the per-state and per-hour math. The appliance wattage chart shows how halogen bulbs compare to every other appliance in a home, and the state rates guide has the current 2026 rate for where you live.
