How do fluorescent bulbs use less energy than incadescent bulbs?
Asked By Oh Snap It's Ashe ♥,Last Answer By noтн!ngнeяe At 2009.12,1 Answers

The filaments inside incandescent light bulbs are very thin, and they offer resistance to the electricity that passes through the bulb. This resistance is then turned into heat. The heat is enough to make the filaments of incandescent bulbs very hot, which then emits light. The filament glows because of the heat that passes through the bulb.

However, the heat uses A LOT of electricity. The heat isn't light, and the purpose of incandescent light bulbs is to create light. Basically, all of the electricity used to create the light is wasted to heat the filament, and use a lot of energy.

Fluorescent bulbs use a much different approach when creating light. At each end of a fluorescent tube are electrodes, which is a solid electric conductor through which an electric current enters or leaves. Inside the fluorescent tubes is a gas which contains mercury and argon vapors. Coating the interior of the fluorescent tubes are phosphors, which are substances that exhibit luminescent when struck by lights, sucgh as ultraviolet rays.

Electricity passes from one electrode to another, and the electrodes collide with mercury atosm, which excites them. As the mercury atoms excite and un-excite, they give of what are called ultraviolet photons. The photons then hit the phosophors, which then create light. There is a simpler version in the website provided in the Sources box.

The reason that fluorescent bulbs are more energy-efficient than incandescent bulbs is that they produce a lot less heat then incandescent bulbs. Fluorescent bulbs produce between fifty (50) and one-hundred (100) lumens (unit of luminous flux), making fluorescent bulbs four to six times more energy-efficient than incandescent bulbs.

I hope this helped.

How far apart should bulbs be planted?
Asked By greengo,Last Answer By MG At 2010.01,1 Answers

I followed instructions on the package for my lilies, tulips, and daffodils, measuring how deep and how far apart. BUT now they look so sparse! I thought maybe they would spread, but they didn't. How do people get the thick bunches of tulips and such? Do they plant the bulbs all in the same spot? Why do the instructions say they must be 6" apart? I don't get it.

Asked By BOO!,Last Answer By Dad's found yer scoo'er At 2009.12,1 Answers

I have yet to find one with a decent light output and am switching back to the old style while they are still available. I have also heard that should you accidentally break one they have a very high level of mercury and which could be dangerous.
