im thinking of using energy saving light bulbs and now dont get me wrong,,i know that they are cheap and save a lot of energy,,,but im not sure what you have to do to dispose of them so,,please tell me when you answer this question.

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.

So called Energy saving light bulbs ??
Asked By Wal,Last Answer By Engineer At 2011.03,1 Answers

These bulbs are normally quite expensive as they look more complicated to make, so the question is, Do the firms who make them use a lot more energy to make them than we save when we use them, as they are full of gas, plastic, electronic stuff and the glass part seems to be a lot more bulky.

Are energy saving bulbs actually environmentally friendly?
Asked By Charlie Brigante,Last Answer By suebob At 2011.03,1 Answers

They say that energy saving bulbs (like the ones you can buy everywhere now - with small flourescent tubes) consume less than 20% of the power of normal bulbs. This is great from an environmental point of view - apparently. But doesnt anyone ever stop to think about the energy processes gone into making them? The chemicals used and the resources needed to manufacture them? Surely making a PCB, assembling the components, manufacturing the tubes, coating them with phosphor etc. etc. is far more damaging to the environment than using a spherical blown bulb with a bit of tungsten in it? I'd like to do some research into this to find out exactly how much energy these so called energy saving bulbs actually save???

How do fluorescent bulbs use less energy than incadescent bulbs?
Asked By Oh Snap It's Ashe ♥,Last Answer By noтн!ngнeяe At 2011.03,1 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.
