Why ordinary bulb has short life?
Because an 'ordinary' bulb has a metal filament which glows through resisting the electricity flowing through it. This eventually weakens the filament and it breaks. The 'energy-saver' bulbs are basically miniature fluorescent tubes - these have electrodes at either end of the tube which generate electricity, this 'excites' the molecules of the fluorescent coating - producing light. They only fail when there's no more coating inside the tube - which means they last MUCH longer !
Which bulb is fuse 25w or 100w which is connected in parallel?
Florescent tube
What types of bulbs used for street lighting?
You may use electronic bulb of any kind in your street. It is entirely depends upon your choice but the main thing you should keep in mind that their light should be of white color like tube light. Because it will be more difficult to see things in some other color other then the white one.
What is the function of the choke in a hpsv lamp?
The function of any ballast in a lighting fixture is to raise the voltage high enough to strike an arc through the bulb or tube.
Is tube light run without choke?
No it will not. If you need increase the supply voltage and remove the choke.
Is a T8 ballast and T8 bulb more efficient then a T12 ballast and a T8 bulb?
In a T* ballast and T8 bulb more energy efficient then a T12 ballast and a T8 bulb? A:Depends on the CURRENT through the tube. When the Tube is run at 100% of rating, The T12 Takes more CURRENT to give a certain Brightness. Because the surface of the T8 is closer to the ion stream through the tube, it takes less CURRENT to light up the T8 to the same brightness. However, IF you use a T12 in a T8 ballast, you will get LESS CURRENT through the tube, and LESS POWER consumed ALONG with LESS Light.
What energy changes takes place as a tube light is turned on?
When a tube light is turned on, electrical energy is converted into light energy and heat energy. The electricity passing through the tube light ionizes the gas inside the tube, which then emits light. Some of the electrical energy is also converted into heat energy due to resistance in the circuit and the inefficiency of the light production process.
What are the benefits of using a tube light bulb compared to traditional incandescent light bulbs?
Tube light bulbs are more energy-efficient and have a longer lifespan compared to traditional incandescent light bulbs. They also produce less heat and provide a more consistent and even light distribution.
What are the benefits of using a tube LED light bulb compared to traditional light bulbs?
Tube LED light bulbs have several benefits compared to traditional light bulbs. They are more energy-efficient, have a longer lifespan, produce less heat, and are more environmentally friendly due to their lower energy consumption and lack of toxic materials like mercury.
What is a dropper and what are its uses?
A dropper simply is a small tube with a air-filled bulb at the top. You squeeze the bulb at the top and whatever substance the tube is submerged in, it will be pulled up into the tube. After that, you lightly squeeze the bulb again to release the substance in the tube out.
What is a long bulb?
A Tube-light !
Why does a tube light cast a dim shadow than a bulb?
A tube light casts a dim shadow compared to a bulb because the light emitted by a fluorescent tube is more diffused and spread out, resulting in softer edges and less contrast in the shadow. Conversely, a bulb emits light in all directions, including towards the shadow, creating a sharper and darker outline.
What are compact flourecent lamps?
A Compact Fluorescent Lamp (CFL) is type of energy-saving bulb made from a small glass tube which is filled with mercury vapour. It has a phosphorescent coating on the inside of the tube which glows...
What are the benefits of using a LED tube light bulb compared to traditional fluorescent tube lights?
LED tube light bulbs have several advantages over traditional fluorescent tube lights. They are more energy-efficient, have a longer lifespan, produce less heat, and contain no harmful mercury. Additionally, LED tube light bulbs provide better light quality and can be easily dimmed or controlled for different settings.
How do you increase sensitivity of mercury in glass thermometer?
Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. More sensitive means more noticeable expansion. So if you want to increase the sensitivity, you could have a thinner capillary tube, a larger thermometer bulb etc. :)sailesh
Can you save energy by using tube lights?
Whether you'll save energy depends on how you will use the lighting. Tube lights tend to draw a high current when they "start up". If you intend on leaving them on for long periods of time then yes, you will probably save energy. But if you use them to turn them on and off a lot in a short period of time I would say no. That's the reason why a lot of big office buildings in big cities like New York never turn off their tube lighting at night.
What are the best lighting options for a room that require an f40 bulb?
The best lighting options for a room that require an F40 bulb are fluorescent tube lights. These lights are energy-efficient and provide bright, even lighting for the room.
