The weight of one 8 foot fluorescent light bulb is 1.2 pounds. Fluorescent light bulbs are available in many colors and color temperatures.
The average fluorescent light bulb weighs about 3 to 5 ounces. That would make the weight of four of them to be about 12 to 20 ounces.
Compact fluorescent light bulbs weigh between 120 to 453 grams or 4 to 16 ounces. The light bulbs were introduced in the states in 1979 and gained popularity quickly.
don't know that's what i am trying to find out
in foot-candles. i.e. the brightness of a candle one foot away
the average weight would be 90 - 100 pounds.
The range of granite density is from 144 to 170 pounds per cubic foot (lbs./ft^3). In order to know the weight of your granite its exact density and volume must be determined. Dividing the known density by volume will tell you its weight.
The question cannot be answered because weight depends on the force of gravitatonal attraction which varies between locations. In outer space, for example, a cubic metre of mercury would weigh nothing. Even on the surface of the earth the force varies by up to 5%.
A cane's main function is to provide stability for those with balance issues, as well as the transfer of weight off an injured leg or foot.
A four foot tube is about $4.95.
35 watt
It depends. If you have a compact fluorescent bulb, it is about the same difficulty level as installing an incandescent bulb. If however you are installing a 4 foot long fluorescent tube, it may be considered a bit more difficult because there are 2 pins on each end of the tube that have to line up on each end of the light fixture, thus it would require a bit more effort and coordination. Once you line the end pins up, you push the tube into the slot until it is fully seated, then you give it a quarter turn to lock it in place.
A foot candle refers to the the amount of light a light bulb, sun.. etc puts out.
There are actually a wide variety of different kinds of 4 foot fluorescent lamps, which do not all use the same amount of energy. However, 40 watts is typical.
The weight of a foot ruler is probably about 1 pound a little under a pound, but it is extremely light.
Depends on how high it is off the floor. Make sure you buy a T8 and not a T12. The T8 puts out more light and will operate at a lower temperture. On a normal 8' ceiling a 2 bulb T8 will cover around 36 square feet of space. If the room is pretty large then an 8 foot 2 bulb HO light is a much better choice.
About 1.2 pounds.
Eight feet
No, although (at least in North America) a 2-foot size is by far the most common.
Electricity goes through the "electrical foot contact", heats up the wires (connected to the tungsten filament) therefore lighting the light bulb up. The filament is supported by wires. The glass mount holds up the two wires connected to the filament. That is how I think the light bulb works. Have a look.
