Okay, the light in my room went out last week. This week I started using a lamp. Does using the lamp save energy, rather then the light in my room or, does it matter?
It depends on the wattage of the light bulbs. A lot of light bulbs have the wattage written on them.
Lets say that the ceiling light fixture in your room had 2 100w bulbs and your lamp had a single 60w bulb. In this case your fixture uses over 3 times as much electricity as your lamp. I don't know if this is the case, just making an example.
If your fixture and your lamp have the same wattage bulb than it doesn't make any difference.
As jack1981 said, compact florescent bulbs do save energy. However, they also have mercury in them and shouldn't be disposed of in your regular trash. Since most poeple just throw them away anyway is the benefit of using less electricity greater than the harmful release of small amounts of deadly mercury into the environment?
Hopefully in the near future LED lighting will become competitive and replace both incadescent and florescent lighting.
I assume the lamp you mean here means conventional light bulbs.
The purchase price for Compact Fluorescent Lamps (CFLs) is more than conventional light bulbs, CFLs last 10 times longer and provide equivalent light. Furthermore it use 75 percent less energy.
So in my opinion, if you on the light for short period (about 1 or 2 hours) a day. It doesn't matter whether you use CFL or light bulb. However it is recommended to use CFL because it saves energy = saves our mother earth.
haha there boththe same thing to me you shud use buls that save energy though if you care about are planet an you shud also recycle even though that has nuthin to do with your question but hey im giving you advice that you dont even have to ask haha
