How much energy does an LED light use? (Tell me about them please)?

Question

Also what are some energy saving methods i could use around my house?

Answer 1

At the mention of 1/10th the power of a typical incandescent, that would mean you get approx the same light output at the power level of an incandescent nightlight as a 75-watt incandescent bulb.

Answer 2

An led (or light emitting diode) uses almost no energy when compared to a regular light bulb. Instead of a heavy tungsten filament, it uses two semiconductors to exchange energy (in the form of light energy) from a positive end to a negative. If you want to cut down on energy costs, you can switch your old light bulbs for those newer energy saving ones (you can find them at wall mart for less than 5 dollars). But if you really want to cut down on energy usage, then this summer, keep your AC 2 degrees higher than you normally would.Taking slightly colder showers is also a good way.
