Light Bulbs and Artificial Lighting

No Fruits will light up a light bulb because any fruit doesn't have any electrical energy in it :)

The only alternative to artificial lighting is natural lighting and that is available only a portion of the day unless you happen to have some sort of photo-luminescent life form in your home; however, biological light is typically very dim.

Filament gets heated when an electric current passes through it, causing resistance in the filament wire. The resistance converts electrical energy into heat energy, which then causes the filament to reach high temperatures and emit light.

The hot filament in an incandescent light bulb is protected by a glass bulb filled with an inert gas, such as argon or nitrogen. This gas prevents the filament from reacting with oxygen in the air, allowing it to glow and produce light.

If you cannot unscrew the existing bulb, first ensure the power is turned off at the circuit breaker for safety. Use a rubber grip or cloth to increase friction and try turning the bulb again. If it’s still stuck, carefully apply penetrating oil around the base and let it sit for a few minutes, then try again. If all else fails, you may need to remove the fixture to access the bulb from behind.

Fluorescent light bulbs have an inner wall coated with phosphor powder. This coating converts the ultraviolet light produced by the bulb into visible light when it strikes the phosphor.

I think there is no 3 way LED light bulb :) :P :)

G40 lights are often used on Christmas trees. These lights are slightly bigger and brighter than traditional tree lights and are also safe to use outdoors.

The lifespan of a light bulb varies depending on the type. Incandescent bulbs typically last about 1,000 hours, while compact fluorescent lamps (CFLs) can last around 10,000 hours. LED bulbs, known for their efficiency, can last between 15,000 to 50,000 hours or more, making them the longest-lasting option available today.

If you are not replacing all of your incandescent bulbs with CF bulbs, then some installations may be of more benefit than others. To maximize savings on operating costs, put them in light fixtures which stay on more than others.

Put one in a fixture that's hard to reach; that way you won't have to change it as often.

Do you have a fixture that has a maximum wattage rating of 60 watts (like many of the 'builder-grade' fixtures in my house)? Replace the 60 watt incandescent bulbs with 23w CF (100 watt 'light-equivalent') and you'll get more light into the room.

Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.

Because it is much easier to use than heavy.

The brightness of a light bulb decreases as the distance from the light source increases because the light spreads out over a larger area. This phenomenon is known as the inverse square law, where the intensity of light diminishes proportionally to the square of the distance from the source.

Modern CFL and led bulbs will not be appreciably effected by the number of on-off cycles. Older tubular florescent lamps have a filament for start up, and lifespan can be reduced by number of cycles. If operated outside rated environmental temperatures, however, some lamps can be stressed by heating and cooling of the electronics.

Quicksilver, also known as mercury, is used in fluorescent light bulbs. It is a key component in the vapor inside the bulb that emits ultraviolet light when electricity is passed through it, which in turn excites the phosphor coating on the inside of the bulb, leading to visible light production.

Energy-saving light bulbs, such as compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs), work by converting electricity into light more efficiently than traditional incandescent bulbs. They produce less heat and use less electricity to generate the same amount of light, resulting in reduced energy consumption and lower electricity bills. This efficiency is achieved through the use of different materials and technologies that minimize energy loss and maximize light output.

The lightbulb for the Jenn-Air stove model D146-C is typically located inside the oven cavity, often near the back or on one side. To access it, you may need to remove a cover or shield, which is usually held in place by screws or clips. Always ensure that the stove is unplugged or turned off at the circuit breaker before attempting to replace the bulb for safety. If you're unsure, refer to the user manual for specific instructions.

Yes; Edison invented the light bulb in 1879, though electric light bulbs weren't the dominant source of light until after World War I. Most Victorian homes used gas lighting or candles.

I think the last person had problems reading the question. It depends on the mood. If you want to read then of course more light is needed or it's hard on the eyes. If it's just to set say a romantic mood or to set a calming state so to speak. You can set it to a down lighting. Just a personal option, your choice.

Compact fluorescent light bulbs are cooler, use less electricity, and last a great deal longer than incandescents. However, they are more expensive than incandescent light bulbs and do contain trace amounts of mercury. They also have a slight delay before turning on.
