How much does it cost to leave a light on for 24 hours?

What is the cost of leaving a fluorescent light on?
When it comes to lowering your energy use and saving a few bucks on your electric bill, the dishwasher, washing machine, and heating are usually the first things that come to mind.
Your light bulbs are probably something you don’t give much thought to. Why? They’re little, so even if you leave them on all day, they shouldn’t use much electricity, right? Let’s take a look to see whether that’s the case.

What is the Energy Consumption of a Light Bulb?
Is it true that light bulbs consume a lot of electricity? While individual bulbs use very little power (about 40 watts), the problem is that you presumably have a lot of them in your home, so the costs quickly add up. Simply count the number of bulbs you have in each area of your home — it might easily be twenty or thirty!
The wattage of each light bulb you purchase will be indicated on the box, allowing you to immediately determine how much energy it will take.
A 60-watt incandescent bulb, for example, will burn for an hour and consume 60 watts. That does not, however, imply that it will produce the same amount of light as a 60-watt bulb.
Incandescent bulbs are the most common type of light bulb. This century-old technique produces light by heating the filament inside the bulb. These bulbs are rapidly being phased out due of their low efficiency. They were installed in 68 percent of U.S. households in 2010, but only 6 percent of homes in 2016 had them.

CFLs (compact fluorescent light bulbs) – This bulb is commonly used as a substitute for incandescent or halogen bulbs, and it comes in two types: screw-in and plug-in.
They are four times more efficient than incandescent bulbs and can last up to ten times longer (a 22 watts CFL will give you as much light as a 100-watt incandescent).

LEDs (light-emitting diodes) are the crown jewels of the light bulb world. This technology is relatively new on the market, but it is unbelievably 90 percent more efficient than incandescent lights and lasts 25 times longer; the bulbs are so tiny that they can be built in any way imaginable.
Despite its widely acknowledged benefits, some people are concerned that LEDs may have negative health impacts, primarily due to the blue light they emit.
How much does a 60 watt light bulb cost if it is left on for 24 hours?
The previously indicated 60 watt incandescent light bulb will provide roughly 800 lumens. A LED bulb, on the other hand, uses just about 11 watts to generate the same amount of light, saving you money on electricity.

If you reside in Texas and haven’t switched energy providers yet, you’re probably paying the normal 12 cents per kilowatt-hour rate. As a result, leaving the lights on all day will cost you:
$5.2 per day = 30 lights x 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents
It’s not the end of the world, but these expenses may mount up rapidly.
Inefficient use of energy Because of Heat Loss
Another disadvantage of incandescent bulbs is heat loss: roughly 90% of the energy is squandered as generated heat, with only 5% converted into visible light.
What Are Some Ways to Save Money on Light Bulbs?
Instead of CFLs or incandescent bulbs, choose LED bulbs the next time you need to replace your lights.
If you currently have 30 lights in your house, switching to LEDs can save you up to $200 each year. Furthermore, an LED lightbulb has a 50000-hour average life expectancy.
That means that if you use it for 10 hours a day for 14 years, it should last you. You’re more likely to change your house before the light bulb burns out.

You can also change electricity providers to save money on the energy your lights consume. If you live in Texas and haven’t switched yet, you’re most likely paying roughly 11.85 cents per kWh.
However, a short search of other suppliers’ offers reveals up various long-term contracts with an average rate of around 5.99 cents, lowering your energy expense even further.
