Which puts out the greater percentage of its energy as light an incandescent lamp or a mercury vapor lamp?
A mercury vapor lamp puts out a greater percentage of its energy as light compared to an incandescent lamp. Mercury vapor lamps are more efficient at converting energy into light, whereas incandescent lamps produce more heat than light, making them less energy efficient.
Why flourecent lamp are better source of light than incandescent lamp?
Fluorescent lamps are more energy-efficient than incandescent lamps because they produce light by exciting mercury vapor with electricity, resulting in less heat loss. They also have a longer lifespan and produce more light output for the amount of energy consumed compared to incandescent lamps. Additionally, fluorescent lamps come in various color temperatures, allowing for more customizable lighting options.
Does a 100w light bulb use more energy than a refrigerator?
No, a refrigerator typically uses more energy than a 100W light bulb. Refrigerators are among the highest energy-consuming appliances in a household due to their continuous operation. In contrast, a 100W light bulb consumes less energy since it operates only when it's turned on.
Less then a few present of the energy supplied to 100w lamp appears in the form of visible light What happens to rest of it What could be done to increase this percentage?
The rest of the energy is dissipated as heat. To increase the percentage of energy converted into visible light, more efficient materials can be used for the filament that emit light more effectively, or the design of the lamp can be optimized to reduce heat loss and focus more energy on producing light. Decreasing the resistance in the circuit or using LEDs can also help improve energy efficiency.

Why sodium lamp is prefer on white lamp during night?
Sodium lamps are preferred over white lamps at night because they emit a warm, soft light that is less harsh on the eyes and causes less light pollution. Sodium lamps also have a longer lifespan and are more energy-efficient compared to white lamps, making them a more cost-effective option for outdoor lighting.
is a toshiba dlp lamp energy costly to have and use?
Toshiba DLP lamps are energy costly to have and use, because they have to be replaced fairly often. More information can be found here: http://www.ehow.com/how_7206948_change-lamp-toshiba-dlp-tv.html
How is sodium lamp different from normal lamp?
A sodium lamp produces light by passing an electrical current through sodium vapor, emitting a yellowish-orange light. On the other hand, a typical lamp, such as an incandescent or LED lamp, produces light through the conversion of electrical energy into visible light using different mechanisms like heating a filament or stimulating electrons in a semiconductor material. Sodium lamps are more energy-efficient but have limited color rendering compared to traditional lamps.
How much electrical energy does a 100W lamp use in 1 hour?
100 Watts is 100 Joule/second. If you want the answer in Joule, you can base your calculations on that. On the other hand, the electrical company will charge you by the kWh. In this case, it is more convenient to calculate as follows: 100W = 0.1 kW, that is the same as 0.1 kWh/hour.
How many types of lamps are there?
There are many different types of desk lamp, ranging from lamps using traditional tungsten (or enerygy saving bulbs) to lamps using the more powerful halogen lamp. These are usually used where brighter light is required.

Why are all CFL lamps more efficient than incandescent lamps?
CFL lamps are more efficient than incandescent lamps because they produce light using a different method - they convert electrical current into ultraviolet light which is then converted into visible light by a phosphor coating inside the lamp. This process is more energy-efficient compared to incandescent lamps, which produce light by heating a filament inside the bulb.
How does lamps save you money and energy?
Lamps save you money and energy by using more efficient light bulbs, such as LEDs, which consume less electricity than traditional incandescent bulbs. LEDs also have a longer lifespan, reducing the frequency of bulb replacements. Additionally, using lamps strategically in specific areas can help reduce the need for overhead lighting, further saving on electricity costs.
