Light Bulbs and Artificial Lighting
Artificial lighting has become standard in the homes and companies of most countries. It is used for concert effects, growing food, and reading a book in bed at night.

What makes a light shine bright in circuit just a simple explanation please?
If it is brighter than it should be there is too much current and it will burn out early.
This is usually caused by internal problems in the lightbulb, but could rarely be caused by excessive voltage in the circuit powering the lightbulb.
If a light bulb is missing in a series circuit will the bulb light?
If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.
If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
Was the light bulb instant success?
No, many people were afraid to use it. Many people left it on all the time because they thought they would get a shock from it. It took a long time for it to get accepted.
Light leaves the lamp and travels in straight lines from its point source. As you move away from the source, the angle between you and the light changes and this the length and position of your shadow changes.
Can I replace 2.5 volt Christmas bulb with 12 volt bulb?
Sure, if you don't mind them being so dim that you probably won't even see them! But it is perfectly safe.
How much money do you save by using a 20 Watt Compact Fluorescent over an incandescent bulb?
An Energy Star qualified compact fluorescent light bulb can save you around $30 over it's lifetime, paying for its self in about 6 months.
Where can I take a burned out energy saving light bulb?
Any Home Depot will accept burned out CFL bulbs for proper disposal and recycling. There's one in Tukwila, close to where you live.
What is Reflection of light called in all direction?
Visible light causes reflection of light in all directions
Were gas lights used often before electric lights?
Yes, gas & kerosene lamps were used exclusively before the invention of electricity.
Why do bulbs have two terminals?
One Terminal Is for Positive And Another Is Negative Wier . Bulb Can't Glow Until Both The Terminals Are Connected
Do regular LED light bulbs function for rough service like garage door openers?
Garage door openers are not classed as rough service equipment. To answer the question, yes a LED lamp will work in a garage door opener unit. LED lamps have no filaments to shake and break. Plus you get the added benefit of the same light output at a lower wattage consumption.
Where can one find recessed light fixtures?
Recessed lighting fixtures can be found wherever lighting fixtures are sold. Some of these stores include Home Depot, Lowe's, Walmart, Target, and Sears.
Why does an electric bulb bang when it is broken?
Light bulbs have most of the air removed, that is there is a partial vacuum inside the bulb. So, when they break atmospheric pressure pushes the on the glass where it is weakened and air rushes somewhat violently into the bulb.
How can you find out if your fluorescent lights are using too many amps?
The amperage is printed on the ballast. If your meter reads higher that that what is printed there, then the ballast is drawing more amps that it should.
Before we begin, a note: At 3.6 volts and 350 milliamps per LED, this leads to just over one and a quarter watts, not the one watt you specified.
Now, for a 12 volt adapter, each LED would only receive one third of its rated voltage if you wired each LED in series. If you wired them in parallel, you would draw a lot of power, but end up burning out the LEDs with almost 4 times its rated voltage.
You would need to wire 3 of the adapters in series, have the 36 volt output wired to the LEDs in series, dividing by ten, giving you 3.6 volts per LED.
How do energy saving light bulbs reduce pollution?
Energy saving bulbs doesn't produce more heat compare to other bulbs. Therefore content of pollution is less by using the energy saving bulb. Even by using a vocca adapter to the normal bulb we can reduce the pollution. Vocca adapters are energy saving adapters. And also vocca adapter is a voice activated adapter.
Why does tungsten halogen lamp have a longer life span than the tungsten filament lamp?
One of the problems all incandescent lamps have is evaporation/sublimation of the filament. You might have a hard time imagining a metal like tungsten becoming vapor, but it does, its slow but the filament does turn to vapor. In ordinary lamps this hot tungsten vapor condenses out on the cool glass envelope, darkening it. The filament slowly gets thinner too and as it does some parts begin to thin faster, those parts get hotter causing the tungsten to evaporate faster making them thin even faster. Eventually some part of the filament gets too thin and the lamp burns out.
In a halogen lamp part of the fill gas of the lamp is a halogen (e.g. chlorine, bromine). Metal vapor and the halogen gas react, creating a metal halide gas. High temperature breaks down this metal halide gas, depositing the metal and reforming the original halogen gas (the catalyst). As the highest temperature in the lamp is on the filament (with the hottest parts of the filament being the thinnest), the tungsten is deposited right back on the filament where it came from (with more of it being deposited on those parts that are thinnest, thus patching them back up). Thus since the filament in a halogen lamp thins much much more slowly (and is self patching when spots thin faster, instead of running away and thinning even faster) than that in an ordinary lamp it takes much longer before it burns out.
Was the light bulb patented more than once?
Every invention has multiple patents often by many different people. Each patent covers different parts of the invention, improvements to the invention, or even effectively useless changes to the invention that allow an inventor to extend their patent coverage.
Is e27 American standard for light bulbs?
Yes, e27 light bulbs are standard light bulbs in America. The e27 LED bulb is an indoor flood light. Review sellers to find ENERGY STAR rated light bulbs.
Why a lighted electric bulb connected to the main should not be touched?
do not touch alighted electric bulb conncted to the main
The led street light performance?
LED is the new trend in lighting for outdoor street lights. Their performance is far more superior over standard lights due to their energy efficiency as well as the illumination effect that these lights cast off.
How do you get light bulbs in don't starve?
Light bulbs are picked from Light flowers, which grow in caves. Find a cave by mining a sink hole.
