Because more energy goes through it, you pay more and you get more result.
AnswerA 100-W lamp has a lower operating resistance than a 40-W lamp. Since power is equal to the voltage squared divided by the resistance, for a given voltage the power will be higher and its operating temperature (therefore brightness) will be higher.

How many lumens is equal to 5 watts?
There is no direct conversion . . . different types of lamp bulbs put out different amounts of light per watt.
Are osram bulbs normally safe to use?
Osram bulbs are high quality compact fluorescent bulbs that help to your home save energy and money. Osram bulbs are extremely safe to use as they have passed many safety regulations.
How many 50 watt light bulbs equal 1 megawatt?
This depends on the wattage of each bulb. If each bulb is, say, 100 watts, you can power ten thousand bulbs. To calculate for your own bulbs, divide 1,000,000 watts by the wattage of each bulb.
How many light bulbs are on the Verazzano Bridge?
262
How long did the first light bulbs last?
Many of Edison's first bulbs lasted less than 40 hours.
What happens to the brightness of the light bulbs in a parallel circuit if we add more light bulbs.?
In a parallel circuit, adding more light bulbs does not decrease the brightness of the existing bulbs. Each bulb operates independently and receives the full voltage of the power source, so their brightness remains consistent regardless of how many bulbs are added. However, the total current drawn from the power source will increase with each additional bulb.
How many incandescent watts are in 80 LED?
There is no direct conversion between watts of incandescent bulbs and LED bulbs, as they are measured differently. However, on average, one 10-watt LED bulb is equivalent to an 80-watt incandescent bulb in terms of brightness. So, you would need 8 LED bulbs at 10 watts each to match the brightness of an 80-watt incandescent bulb.
Are ordinary light bulbs rated in terms of luminosity or brightness?
Yes, ordinary light bulbs are rated in terms of luminosity (which is generally understood as a measurement of brightness) AND voltage AND current. And physical size AND type of base (screw in, bayonet and which size?).There are many parameters that a light bulb can be rated by.
What is the value of resistor do you use in 2.5volts bulb with use 4 batteries with 1.5volts?
If your batteries were in series the total voltage would be 6 volts, and it the bulbs were in series you would need a resistor to keep them from burning out. In order to know how many ohms the resistor would need to be you would have to know the wattage of the bulbs, or the resistance of the bulbs. If you don't know the best thing to do is use a variable resistor. Then you can adjust it or the brightness that you want.
Does the brigthness of a bulb stay the same in a parellel circuit no matter how many bulbs are there?
If all the bulbs are connected in parallel, and there is enough current, yes, the brightness will be the same. The voltage (which is the amount of energy in every charge), remains the same for all bulbs
What do you notice about the brightness of the bulbs in the parallel curcuits as you add more bulbs to it?
Nothing if the current capacity of the circuit is not exceeded. The extra bulb will draw more current and if the limit is not reached all bulbs will continue at their rated brightness. If the current capacity is overrdrawn either the circuit breakeer will break and stop all lights or if the capacity is not fused all lights will dim.
How many 48 fluorescent light bulbs are needed to fully illuminate the entire office space?
The number of 48 fluorescent light bulbs needed to fully illuminate the entire office space depends on the size of the space and the brightness of the bulbs. It is recommended to consult with a lighting specialist to determine the exact number needed for optimal illumination.
How many 100W bulbs run from 1 megawatt power station?
A 1 megawatt power station can power 10,000 100W bulbs. This is because 1 megawatt is equal to 10,000 100W bulbs in terms of power consumption.
Would you need half a million full moons to equal the brightness of the sun?
The apparent magnitude (AM) [See Link] is a measure of its brightness as seen by an observer on Earth, in the absence of the atmosphere. The brighter the object appears, the lower the value of its magnitude. The Sun has an AM of -26.73 whereas a full Moon has an AM of -12.6. The scale is logarithmic: the relative brightness of two objects is determined by the difference of their magnitudes. Pogson's Ratio was suggested in 1856 so that each decrease in magnitude represented a decrease in brightness equal to the fifth-root of 100 (or about 2.512) So, the difference in magnitude is (-12.6) - (-26.73) giving 14.13 Thus 2.51214.13 = 449,032. Close enough to half a million.
How many light bulbs would you burn out by using 88000 kilowatts?
If you used them simultaneously, probably around 1.46 million 60Watt bulbs.
How many pages does Brightness Reef have?
Brightness Reef has 518 pages.
Have a regular fixture with 3 60 watt bulbs now want to convert to a LED fixture with the same amount of light how many LED watts do I need to get the same effect?
I cannot tell you as this will vary from brand to brand of LED lightbulbs. Look on the package for the "equivalent wattage" rating and buy bulbs rated at 60W equivalent. You should not need to change the fixture, just put LED lightbulbs in the one you already have.
