Even, what light bulb is the cheapest? Starting at $1.25 per bulb, CFLs are a budget-friendly choice. They're almost as energy efficient as LEDs but take at least 30 seconds to reach full brightness, don't last as long, and most aren't dimmable.

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.

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.
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.
LED bulbs are far more complex than halogens, thus making them more expensive; There's more sophisticated technology both in the bulb and manufacturing process of LEDs. More parts are used be make an LED bulb. Certain components are costly before construction (such as bulbs containing a driver for example)
Are LED Lights Cheaper to Run? LED lights are definitely cheaper than their counterparts. Not only do LED's consume less energy, but the bulbs also use energy more efficiently, which saves a lot of money.
Light Bulbs A LED light bulb uses just seven to ten watts while a fluorescent light bulb consumes 16-20 watts, an incandescent light bulb will use 60 watts typically and cost about 0.6 cents an hour to run, according to the energy use chart.
Less heat. LED lights emit less heat than traditional incandescent and halogen lights. ... Energy Saver, an online resource from the DOE that helps consumers save money, said LED lights use between 75-80% less energy, saving consumers as much as $75 a month.
Energy Cost A 50 watt traditional bulb that runs for a single hour will use 0.4 kWh/day. This means that working for 8 hours per day, it will consume 146 kWh/year.
A single 1.5-watt night light used for 12 hours each day uses about 0.4 percent of the total electricity used for lighting an average U.S. residence. A 7.5-watt night light burning for 12 hours uses about 2 percent of the total electricity used for lighting.

The reference point: a standard 100-watt incandescent light bulb produces about 1,500 – 1,700 lumens. Not a measure of brightness; instead, it's a measure of how much electricity (or energy) a light bulb consumes to reach its claimed brightness....Key Terms.

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.
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.
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.
Leaving a modern TV in standby mode won't significantly increase your electricity bill, but it's still a waste of money. If you want to lower electricity use while the TV is off or on here's what you should do.

Because the truth is, LEDs do cost substantially more. One thing's for sure though, is that LEDs are by far the most efficient lighting solution on the market, consuming the least amount of power compared to incandescent bulbs, halogens, and CFLs.
It is true that the upfront cost of an LED bulb is higher, but there are two factors that actually make it cheaper to own: A long service life. A very low power consumption.
Typically, it costs more upfront to buy a CFL or LED than it does for incandescent light bulbs. ... While the LED costs the most, it lasts at least five-times longer than the Halogen – in other words you'll have to buy 5 halogens – at a cost of $15 – to last as long as a single, $10 LED.
