Can you use a 50 watt halogen bulb for a 100 watt halogen bulb?
Yes. It just won't be as bright.
How many lumens output in a 500 watt quartz Halogen bulb?
The bulb will have an efficacy of 17-20Lm per watt, so in total 500W = 8,500-10000 lumens. However, the bulbs light output is non directional, so a lot of the spilled light is in directions that you don't want it to go, so 50-70% of the figure can be used when specing up an LED variant.
What are Thomas Edison accomplishments?
Thomas Edison is famous for inventing the first long-lasting light bulb. Although he also invented the motion picture camera, the phonograph, and a lot of other great inventions. Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light. So he said. Tesla worked for Thomas Alva Edison for 1 year At that time, the most important "inventor" in the world was named Thomas Alva Edison-the so-called wizard of Menlo Park.... Edison was credited with the invention of the DC dynamo and the electric light bulb . . . but the only thing he really invented was the ELECTRIC CHAIR!!
Will a diode work as a light dimmer when switched or added in series to an incandescent 120 volt AC bulb?
Actually, I have seen this in a respected electronics magazine (Elektor) quite some time ago: A diode (selected to be capable to handle the amps, the voltage and the heat from the bulb - if placed inside the lighting fixture) is used to "cut off" one half of the AC sine wave and thus sending pulses of 120V to an incandescent light bulb, simulating a simple dimming device. The proposal was meant to run 240V bulbs at 50% of their brightness but I am pretty certain this concept can be used to run 120V bulbs from 240V power. One other way of connecting 120V bulbs to 240V would be to connect two 120V bulbs OF THE SAME WATTAGE in SERIES, so the two bulbs form their own voltage divider. Not sure what happens if one bulb burns out - I would expect the other one to blow too, as a dying light bulb represents zero Ohms (plasma/arcing) for a few milliseconds before it goes dark forever.
What is microfarad?
Fifty millionths of a farad, abbreviated as 50 uF. Farad is the unit of capacitance. 50 microamps DC flowing for 1 second will charge a 50 uF capacitor to 1 volt.
Is Watts light bulb OK for weed plant?
Can I use 50 watts light bulb for weed plant
How much does a light bulb weigh?
a lightbulb weighs about 50 grams
What is the mass of the light bulb and paperclips?
251.0
What is the mass of the light bulb?
The mass of a typical incandescent light bulb is around 25-50 grams. LED light bulbs tend to be lighter, around 10-20 grams.
What year did they make the light bulb?
Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879. However, there were several other inventors who also contributed to the development of the light bulb around the same time.
How hot does a 50 watt light bulb get?
This depends on the bulb design. A simple tungsten filament bulb might have a surface temperature of the bulb well above 100 C. A fluorescent lamp will be much cooler for the same light output.
A light bulb has a resistance of 5 ohms and a maximum current of 10 A. How much voltage can be applied before the bulb will break?
50-Voltage
Are cfls good?
Over all, CFL light bulbs are good for the environment and they can save $. 1 CFL light bulb has 10 times the life span of a regular light bulb. 1 CFL light bulb could save enough energy to take a car from NY to San Francisco. 1 CFL light bulb uses between 50% and 80% less energy than a regular light bulb.
What is fifty microfarads?
Fifty millionths of a farad, abbreviated as 50 uF. Farad is the unit of capacitance. 50 microamps DC flowing for 1 second will charge a 50 uF capacitor to 1 volt.
How much stronger is led than a regular light bulb?
50 times stronger from, Keshav
Why does energy saver give more light than electric bulb of same watt?
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
What is the mass of paper clips and a light bulb?
The mass of paper clips is typically around 0.5 grams each, while the mass of a light bulb varies depending on the type and size. For example, a standard incandescent light bulb may weigh around 50 grams.
