How much electricity does a 9 watt LED bulb use?

9 watt led bulb power consumption:

Yearly power consumption = 9*24*365 + 10% power loss = 78840 + 7884 = 86724 Watts hour.

How much does it cost to run an LED light bulb for 24 hours?

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.

How much do LED lights cost to run?

The average total cost per year of an LED light bulb is £2.78, assuming typical usage of 10 hours per day. On an annual basis, with electrical consumption and purchase costs considered, an LED light bulb is 12% cheaper to operate than an energy efficient fluorescent bulb, and 74% cheaper than an incandescent bulb.

How much does it cost to run a 100 watt LED bulb?

We will also assume that a kWh of energy costs 15 cents. Incandescent: A 100-watt, classic light bulb running for a full year would use up 876 kWh of energy. This means a full year of running one incandescent bulb would cost $131.40.

Can I leave LED lights on all day?

To put it simply, well-manufactured LED lights are extremely long-lasting and can be left on 24 hours, 7 days a week. This is because, unlike conventional types of light, LEDs produce minimal amounts of heat, which means they are unlikely to overheat or set on fire.

What is 60 watts in LED?

LED equivalents to traditional incandescent light bulbs

Incandescent Light Bulb Wattage LED Equivalent Wattage
75 Watt 7.5 Watt
60 Watt 6 Watt
50 Watt 5 Watt
30 Watt 3 Watt

Can I replace a 40w bulb with a 60w LED?

When it comes to replacing old incandescent bulbs with LEDs, a common question that customers ask is: “Can I use an LED bulb that has a higher wattage equivalent than my fixture allows?” The simple answer is yes, as long as the LED bulb uses less wattage than your fixture.

Do LED lights make your electric bill high?

LEDs Use Less Energy Than Traditional Lighting Sources

LEDs use between 25- and 80-percent less energy than incandescent lights. According to the DOE, the annual energy cost of a 60 W incandescent light is $4.80, but the comparable cost of a 12 W LED, providing the same light as a 60 W incandescent light, is $1.00.

How much does it cost to run a 60W light bulb for 24 hours?

Jul 25, 2019 · At an average cost of 12 cents per kilowatt-hour, the 60-watt incandescent bulb will cost approximately $17 per year to operate. Regarding this, how much does it cost to run one light bulb for 24 hours? So the cost of replacing per 24 hours will be 24x 2/ 1000 or 4800/1000 cents or 4.8 cents.

How much does 100 watts per hour cost?

Watts X Time / 1000 X Cost per KWH = Total cost. Let’s use a regular 100 watt light bulb for example, lit continuously for one year (8760 hrs.), at a cost of 12 cents per KWH. 100 watts times 8760 hrs. = 876,000 divided by 1000 (converts to KWH) = 876 KWH times 12 cents = $105.12.

How much electricity does a 1000w led grow light use?

You need to divide your wattage by 1,000 (1,000 kilowats in 1 watt). So, if we were to run a 1000 watt grow light 18 hours a day with the kWh rate we gave earlier, our formula would be: 1 x $0.1559 x 18 x 30 = $84.186/month.

Is switching to LED lights worth it?

According to the math above, the monthly usage savings for a single bulb is $1.25. So most people will be able to recoup the cost of a new LED bulb in just over three months. In addition to saving money, LEDs can save you time — with fewer trips to the store and up the ladder. They last about 25,000 hours.

Is it cheaper to leave LED lights 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.

Are LED lights cheaper to run?

The large variance between an LED bulb and, say, a halogen bulb wattage is the reason LEDs are so much cheaper to run. … This means that the LED spot uses 90% less electricity to run and therefore it costs 90% less. We have 6W Led bulbs that are replacements for 60W halogen bulbs, again saving 90% energy and cost.
