No, 50 microamps (0.050 milliamps) is generally insufficient to light up a standard incandescent or LED bulb, which typically requires much higher current levels to operate. Most light bulbs need at least several hundred milliamps to produce visible light. However, certain specialized low-power LED indicators designed for very low current could potentially light up at that level, but they would be exceptions rather than the norm.
Yes. It just won't be as bright.
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.
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!!
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.
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.

a lightbulb weighs about 50 grams

Depending on the type of light bulb the mass can vary. A standard LED bulb weighs 6.2 ounces.
The equivalent light bulb to Sears' halogen light bulb part number 57853 is typically a 50-watt MR16 halogen bulb. This bulb has a similar shape and wattage, making it a suitable replacement for various lighting fixtures that use this type of bulb. Always check the fixture's specifications to ensure compatibility with the replacement bulb.
The average weight of any light bulb varies from type to type. Brands also play a factor in the weight of light bulbs. Typically the average weight of a light bulb is about thirty seven grams.
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.
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.

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.
