Annual cost*\$1.83\$10.95

How much does a lightbulb cost per day?

Let's say you have a 60-watt incandescent lightbulb and you are paying 12 cents per kWh of energy. Leaving the bulb on the whole day will therefore cost you: 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = approximately 20 cents in one day.

### Which bulb is good for home?

Incandescent bulbs and halogen bulbs have the highest wattage, making them less energy-efficient choices. CFL bulbs use fewer watts, but LED bulbs are the real winner in energy efficiency—an 8 or 9-watt LED bulb emits as much light as a 60-watt incandescent bulb.

### How much does it cost to run a light bulb for 1 hour?

So, a 60-watt bulb uses 60 watts hours or . 06 kilowatt hours of energy for each hour it's on. The bulb would use 1 kilowatt hour in just less than 17 hours if left on continuously; around 12 cents in our current tariff for most residential customers.

### Why are light bulbs so expensive?

### What color light bulb is best?

Color temperature Soft white (2,700 to 3,000 Kelvin) is warm and yellow, the typical color range you get from incandescent bulbs. This light gives a warm and cozy feeling and is often best for living rooms, dens and bedrooms. Warm white (3,000 to 4,000 Kelvin) is more yellowish-white.

### What light bulb is like sunlight?

Halogen bulbs are a type of incandescent that gives a close approximation of natural daylight, known as "white light." Colors appear sharper under halogen light and the bulbs can be dimmed. They're a little more energy efficient than incandescent bulbs, but they're more expensive and burn at a higher temperature.

### Is it cheaper to leave a light on?

You should leave the lights on because it takes more energy to turn them back on than you'll save by turning them off. FALSE! Fluorescent lights do take a small surge of power when turned on, but this is significantly smaller than the amount saved by turning them off.
