The light bulbs in your home emit countless photons. These photons are then reflected and absorbed by objects in your room, lighting up the space.
Operating lighting fixtures uses a small amount of electricity, measured in kWh, which is added to your household energy usage. So how long can a light stay on without wasting energy?
Light Bulbs
Light bulbs are used for many purposes, from lighting a room to signaling an electronic device is on. Billions of them are in use around the world. They are typically made of glass and contain a filament that glows when electric current passes through it.
Most electric bulbs are filled with a gas such as argon or nitrogen to reduce the amount of convective loss in the filament, but the earliest bulbs were not filled with anything at all. The tungsten in these bulbs would become very hot and burn up quickly in regular air.
The life time hours listed on a bulb’s packaging are usually tested under ideal conditions, so they may be longer or shorter in real-world situations. Some other factors that affect the performance of a bulb are electrical surges, extreme cold, and vibration.
Halogens
Halogen bulbs are a popular upgrade from traditional incandescent lightbulbs. They last longer than traditional bulbs, and are more energy efficient as well. In fact, halogen bulbs can produce anywhere from 12 to 29 lumens per watt of power, while traditional incandescent lightbulbs only offer up to 18 lumens per watt of power.
Halogens are nonmetallic elements with an outer shell that contains seven valence electrons. Because they are more electronegative than oxygen, halogens can easily gain an electron from another substance to satisfy the octet rule. This results in the formation of compounds with that other substance, including metal halides, which have similar properties as their parent element.
In a halogen light bulb, a tungsten filament is placed inside a heat-resistant envelope filled with halogen gas. When an electrical charge is applied, the filament heats up to about 2,500 degrees Celsius and emits light. In most cases, halogen lamps are mixed with a noble gas such as krypton or xenon to reduce their chemical reactivity.
CFLs
CFLs use less energy than traditional incandescent bulbs and last about 10 times longer. Replacing just one 60-watt bulb with a 13-watt CFL saves the average household $30 in energy costs over its lifetime.
CFL light output is proportional to the phosphor surface area, so it takes time for them to reach full brightness after being switched on. Bare spirals typically take a minute to achieve their rated lumen output, although some premium CFLs are much quicker. Decorative cover styles, including globes and reflector shapes, have slower warm-up times – up to three minutes.
Unlike incandescent bulbs, which emit visible light as they burn, CFLs produce invisible ultraviolet radiation that excites the phosphor coating inside the tube to make it glow. This can cause discomfort for some people, particularly those with lupus or other auto-immune diseases who are sensitive to UV. CFLs also emit some levels of HF (radiofrequency) electromagnetic fields. Health Canada has determined that the EMFs produced by CFLs are negligible at 20 centimeters from the source and in line with international scientific guidelines.
LEDs
LEDs use a special conductive material (typically aluminum-gallium-arsenide) to create photons that the human eye sees as light. Different types of LEDs are designed with lenses or reflectors to either concentrate the light in a small spot or spread it out over a wide area.
While LEDs can be left on for days, they still need to be turned off when not needed. They generate very little heat which makes them less likely to create a fire hazard or burn someone when touched. Their cooler running temperature also limits the amount of internal damage that can occur if they are cycled often like other bulbs.
Like other types of lighting, LEDs do not burn out but they will gradually lose their brightness over time. This is due to thermal management; the faster an LED is able to dissipate its heat, the longer it will last. You can control an LED’s brightness by adjusting the current it draws.
Many people believe that turning off lights is important to save energy and reduce the electricity bill. In fact, rapidly switching light bulbs on and off actually lowers the operating life of any type of bulb.
Truelove et al. [16] found that participants preferred turning off lights above many other pro-environmental behaviors, including improving light bulb efficiency.
Energy
From an environmental standpoint, turning off lights conserves energy. This reduces the demand for power which helps conserve finite natural resources such as trees, coal, and oil. It also helps reduce greenhouse gas emissions which contribute to climate change.
For example, one 40-watt light bulb switched off for an hour will save.06 kilowatt hours of electricity. To determine how much that is worth, simply look at your most recent electric bill, find out what the cost per kilowatt hour is, and multiply by the number of hours the light was turned off.
Interestingly, when participants were asked to recommend the single most effective thing they currently do or could do to save energy, turning off lights was by far the most popular answer. However, replacing inefficient bulbs with efficient ones would actually be more effective for saving energy than simply turning off the lights. These two behaviors should be promoted simultaneously to maximize effectiveness.
Money
Aside from the obvious benefits to the environment, turning off lights is also one of the best ways to conserve energy and save money on electricity bills. Whether the lights are on or off, they’re still sucking up electricity. The more you keep them off, the less you’ll pay each month on your electricity plan from electricity retailers.
The amount of electricity you suck per light bulb depends on the type of bulb and how often it’s used. Incandescent bulbs, for instance, are relatively inefficient and only about 10%-15% of the energy they consume results in light. On the other hand, halogen and energy-efficient compact fluorescent or light emitting diode (LED) bulbs use far less energy than incandescents.
When calculating the cost-effectiveness of keeping a light on, you’ll want to take into account your electricity price per kilowatt hour, which can be found on your most recent electric bill. Generally speaking, you’ll save money by keeping a light off for an hour or more.
Health
In addition to energy savings, turning off lights can help you sleep better. Studies have shown that light exposure at night can inhibit the brain’s ability to reach the deepest stages of sleep, which has a range of negative health consequences.
Incandescent and halogen bulbs are the least energy efficient, with 90% of their electricity being given off as heat and only 10% resulting in light. Turning these off whenever you’re not using them can save a lot of energy, especially when compared to more energy-efficient compact fluorescent lights and light emitting diode bulbs.
Some people worry that switching off lights can use more electricity, since some types of bulbs need a little extra power to start up. However, this “inrush current” only lasts for 1/120th of a second and uses the same amount of energy as only a few seconds of normal operation. In fact, in a study of 74 pro-environmental behaviors, participants ranked turning off the lights as being the lowest in financial and behavioral cost [16]. A habit of turning off lights can go a long way to saving money and energy.
Environment
Turning off lights is one of the easiest ways to protect the environment. This simple act reduces carbon dioxide emissions, which contribute to global warming. It also helps extend the life of light bulbs. All bulbs have a nominal or rated operating life, which is reduced the more often they are switched on and off.
In fact, turning off lights can significantly prolong the lifespan of incandescent light bulbs. This is because the light bulb uses 90% of its energy for heating, while only 10% results in actual lighting. It is even more important to switch off lights when not in use for other types of bulbs, such as halogen and compact fluorescent lamps (CFL) or LEDs.
When participants were asked to rank 74 pro-environmental behaviors on two dimensions—cost and environmental impact/savings—turning off the lights was one of their top three choices, along with recycling and switching to energy efficient light bulbs. This indicates that turning off the lights is still a popular and effective way to conserve energy.
Lights with pull chains are often mounted high in ceilings to keep the bulbs protected from damage. However, this can make them difficult to reach when a chain breaks.
Fortunately, changing a pull chain is an easy fix for an experienced do-it-yourselfer. Just follow these simple steps! The whole process should only take about fifteen minutes.
Turn Off the Power
Pull chain lights are a great way to brighten up a closet or basement/attic space. However, sometimes the pull chains can break. If they snap off just a few inches short of the socket it’s easily fixed with a pull chain extension available at most large home improvement stores.
If the pull chain is stuck or difficult to pull that could be a sign that the switch inside the socket isn’t working properly. In that case you will need to replace the switch.
Always remember to turn off the power to the fixture at the breaker panel before working on it. This will help prevent electrical shock. Using a non-conductive voltage tester is also recommended to make sure the wires aren’t still supplying electricity. This can be purchased at any major hardware store for just a few dollars. Once the power is turned off it’s safe to begin working on the switch and chain.
Remove the Light Bulb
The pull chain lamp is a familiar sight on the desk of many a writer, accountant or seamstress burning the midnight oil. It’s a quick and convenient way to light up one’s work area, but it’s not so convenient when the chain breaks or gets stuck.
Thankfully, changing a light chain is easy and can be done in about fifteen minutes. All that’s needed is a pair of pliers and a bit of patience.
Before you start, disconnect any electrical wires connected to the switch and the fan (this may require climbing up a ladder). Then, remove the bulb and light kit from the housing unit. Take note of how the wires are arranged so you can reattach them correctly. Finally, screw the cover and accessories back in place. Once everything is in place, you can give the new pull chain a tug and enjoy the sense of accomplishment! And don’t forget to turn the power back on at the circuit breaker.
Remove the Switch
Once you’ve figured out what the problem is and turned off the power at your circuit breaker or fuse box (and double checked with a voltage tester), it’s time to remove the fixture from the ceiling. Take down any breakable light bulbs and pull chains to prevent damage and set them aside. Next, remove the end cap by turning counterclockwise to remove it from the fixture. Locate the wire connections to the switch and disconnect them.
If your chain seems stuck and twisted inside the switch, spray it with a non-conductive lubricant. If this doesn’t help, you may need to replace the switch altogether.
Once you’ve removed the old switch, install the new one. Connect the new wires to the switch (black to black, ground to ground) then screw the switch back into place. Finally, reattach the end cap, replace any lights or coverings and turn on the power to test your newly-installed pull chain switch.
Replace the Chain
Pull chains are common in many light fixtures, especially those found in attics and basements, as a convenient way to turn the fixture on when it’s out of reach. However, when they break it can be tricky to know how to fix the problem.
If the chain simply snapped in a spot that’s shorter than it should be, you can snap a new link onto the end of the broken chain to lengthen it. Otherwise, a trip to the hardware store is in order to get a replacement switch with chain.
Once you have your new switch and chain in hand, shut off the power to the circuit breaker that serves the light. Unscrew the old switch and wires from the fixture and carefully connect them to your new switch, remembering to pair black to black and ground to ground. Screw the end cap back on and replace any covers and bulbs before turning the power back on and giving your new chain a test tug!
To turn off the light in Japanese, we use the verb . is also used for other everyday electronics and appliances like the air-conditioner (Eakon) and TV terebi (Terebi).

Harry Potter Phone Tricks – How to Turn Off Light With Siri and Google Assistant
Fans of Harry Potter can now use a few spells to perform simple tasks on their smartphones. The trick involves using Apple’s Siri and Google Assistant. To make it work, you’ll need to install a free app called Shortcuts.
The wand-lighting charm Lumos works on iPhones and Android phones. The summoning charm Accio can be used to open apps on iPhones.
Lumos
One of the easiest spells in Harry Potter is Lumos, a wand-lighting charm that illuminates a wand tip. The corresponding counter-spell, Nox, darkens a lit wand. Fortunately for muggles, you can use this spell with your iPhone or Google Pixel device, which uses Siri or Android Assistant. Just wake up your AI software by saying ‘Lumos’ or ‘Nox,’ and it will turn on the phone’s flashlight. This trick works on all Android phones running Lollipop and higher. It also works with a number of smart home devices, including Philips Hue and LIFX.
You can also use the Shortcuts app to create shortcuts that perform these spells. For example, you can create a shortcut that opens an app by saying “Accio” or “Homenum Revelio.” Just remember to enable Hey Siri first to trigger these commands.
Another option is to connect your device to smart lights. You can then say “Hey Siri, Lumos Maxima” to activate the lights and “Hey Siri, Nox” to turn them off. This will make your iPhone feel like a wizard’s wand, though you’ll still be unable to fly away on a broomstick. However, you can make your iPhone levitate using a different method. Read on to learn more about this.
Nox
The counter spell to Lumos is Nox, which darkens a lit wand tip. It’s used by Harry and Hermione when they exit the Shrieking Shack at Gringotts or at other times when their wand light isn’t needed. Nox comes from the Latin for night or darkness, which makes sense as a way to shut off the light that a wand-lighting charm creates.
While these three enchantments are fun, they may feel a little limited if you’re a true Potter fan. Thankfully, the Shortcuts app allows you to turn any spell or charm into a Siri shortcut, giving you access to a wide range of your iPhone’s features.
To start, make sure that Hey Siri is turned on in your device’s settings. Then, open the Shortcuts app and create a new shortcut with the action “Hey Siri, perform [spell or charm]”. The shortcut can then be triggered by saying “Hey Siri” and performing the spell’s incantation. You can also add additional actions to customize the shortcut. For example, you can turn the Accio summoning charm into a command to open an app by adding ‘Set Launch App’ and setting it to your favorite app. You can even use a variation of this command, Accio Maps, to activate Apple’s Maps without pressing any buttons.
Accio
Accio is a summoning charm that pulls objects towards the spell-caster. It can be used on enemies, but players can also use it to Levitate objects and items in the game. It’s one of the more useful spells in the game, particularly outside of combat.
In Harry Potter, this spell was used to summon Newt Scamander’s Firebolt broomstick and to retrieve the Triwizard Cup. It can even be used to summon a certain piece of gear in the game, such as Hermione’s cloak or the Horcrux books.
The player must be pointing in the direction of the object when they cast Accio, and it’s important that the object is outlined in white before casting the spell. It’s also possible to name the item before using the spell, which seems to help concentration.
Interestingly enough, Accio can be used to open almost any app on an iPhone, including secret written messages. To do this, simply say “Ok Google,” followed by “Accio,” and the app you want to open will appear. This is a great way to use the spells on an iPhone without downloading a third-party app. However, it’s not working for the Sword of Gryffindor, which accio can’t seem to summon. Hopefully, this will be fixed in the future.

Many passengers are confused by the custom of dimming the cabin lights as the plane descends to land. This is a necessary safety protocol that protects pilots, air traffic controllers and passengers.
There are several reasons why airplanes dim their cabin lights for take-off and landing. The most important is passenger safety. When an emergency occurs, passengers need to be able to evacuate the aircraft quickly. It can be difficult to do this if the eyes are still adjusted to light.
Safety
The main reason airplanes dim their cabin lights during takeoff and landing is for safety reasons. It’s important for pilots and air traffic controllers to be able to see the aircraft clearly on the runway. Keeping the cabin lights on can distract the pilots and interfere with their vision.
Similarly, the passengers’ eyes must be adjusted to darkness before an emergency evacuation can take place. If passengers disembark into a pitch-black plane, they would have trouble finding their way around. The practice of dimming the cabin lights during take off and landing helps passengers become accustomed to darkness, allowing them to react quickly in an emergency situation.
Nevertheless, the cabin lights are not turned off completely during takeoff and landing. Some lights, including emergency exits and flight paths, remain illuminated. This allows passengers to still find their way out of the plane if necessary and also makes it easier for crew members to spot potential hazards.
Energy Savings
A plane’s lights use up a lot of energy, and keeping them on during takeoff and landing adds to the stress on the engines. Dimming the cabin lights helps conserve power, and it also makes it easier for passengers to see the emergency exits in case of an evacuation.
Another reason for dimming the cabin lights is to allow passengers’ eyes to pre-adjust to the darkness. It can take up to 30 minutes for the human eye to adjust from a well-lit environment, and that time could make all the difference in a crisis.
Another way that airlines save power is by using white wingtip strobes (the flashing lights you see when looking up at airplanes in the night sky). The crew can toggle these lights between ON, OFF, and PULSE. Typically, the strobes are ON for cruise and OFF during descent, with a switch to PULSE at low altitudes and when approaching the runway.
Passenger Comfort
As soon as the cabin lights dim, most air travelers know that their flight has cleared takeoff or is in the final stages of descent before landing. It’s a widely-known aviation safety procedure, and for good reason.
The main reason planes turn off their cabin lights is to give passengers the best visibility possible in the event of an emergency situation during the most dangerous parts of a flight. The human eye needs a moment to adjust from an illuminated environment to a dark one, and this visual adjustment could cost precious seconds in the case of an emergency evacuation.
The dimming of the cabin lights also helps passengers easily identify the “EXIT” signs located throughout the airplane. In addition, it makes the bright white anti-collision lights on the wing tips more prominent. This is especially important during nighttime takeoffs and landings when other aircraft may be flying in the vicinity. This way, the crew can quickly point out where to locate their emergency exits to save valuable seconds when it comes to an emergency situation on the ground.
Visual Adjustment
The most important reason cabin lights are dimmed during takeoff and landing is a safety precaution. In the unlikely event that an evacuation is required at these critical stages, passengers would need to quickly adjust from a brightly lit cabin into pitch-black darkness. This can save valuable seconds as passengers follow the evacuation directions and find their way to the nearest exit door.
This is also why flight attendants ask passengers to keep their window shades open during these periods. It helps their eyes pre-adjust to the dark conditions outside the aircraft, so they can easily see emergency lighting and walkways in an emergency evacuation.
In addition, keeping the cabin lights off prevents glare from disrupting pilots’ night vision while navigating the runway for landing. Airplanes have a three-position switch for their landing lights: ON, OFF, and PULSE. The ON setting is used when the airplane is in cruise and the OFF and PULSE settings are used during takeoff and landing.
