There’s some explained that a dimmed light bulb that is dimmed from a switch use less electricity.  However, this is not as efficient as you thought. Dimming  an incandescent bulb is less efficient than using a lower wattage of a light bulb. For example, dimming a 60W bulb to the brightness of a 40W bulb will use more energy than a 40W bulb on maximum. Plus, dimmer itself uses some power.  

What is the best way to use less electricity?  I would suggest getting a LED bulb, even though it’s more expensive.  

If you’re a fan of Edison bulbs, don’t worry about that. Nowadays, the new version of dimmer helps to save energy and also prolong the life of your bulbs, which making bulbs running at lower power with less stress. Or, you can choose those dimmer designed just for incandescent bulb. They use high frequency switching that turns the supply on and off continuously several times per second, which is giving less power to the bulb.  

Edison bulbs are for creating a moody, soft and warm lighting instead of home illustration. It’s all depends on how you would like your home look like. Having a moody or an energy saving lighting? The LED Edison bulb is a great choice to serve both purposes. The new version of Edison LED bulb keep the original old fashioned Edison incandescent squirrel cage design, serving the moody lighting effect, energy efficient and save money. We have 3W, 4W and 5W LED Edison bulb with warm vintage color ranging 2200 to 2600 Kelvin. Comparing with 2700 Kelvin traditional Edison bulbs, the LED Edison bulbs are more rustic, warm and moody, and of course is more energy saving.  More and more restaurants and design firms are using Edison LED bulbs. I am sure such fever still goes on during 2016.
