Difference between Different Kinds of Light Bulbs

Incandescent bulbs are the least efficient

In fact, they can be considered outdated. In the United States the manufacture of incandescent bulbs stopped in 2013 for outbreaks of 75-100 watts and 2014 watts for 40-60. They served us well for more than a century, but the era of the incandescent bulb is over. And there are LED bulbs that look like the retro bulbs.

How an incandescent bulb works? The electric current passes through a thin wire inside the bulb, heating and emitting light. 90% of the energy is lost in heat.

Fluorescent bulbs (CFLs) are an intermediate step: neither the best nor the worst

They cost a little more but last longer hours and use 75% less energy than incandescent bulbs. However, they contain mercury, which is a hazardous substance and requires special handling when discarded. It is more efficient but is not the most eco-friendly option because of its mercury content.

How does a CFL (fluorescent) work? The electric current passes through a tube containing argon and mercury, producing light through a chemical reaction.

The LED lights (light emitting diode) are the best long-term option

From first glance, the LED lights, like the white corn bulb, seem to cost you a pretty face. However they are much cheaper in the long term as they last at least 25 times longer than incandescent bulbs and consume about 80% less energy. In addition, many brands of LED bulbs provide guarantees of up to 10 years. The LED bulbs, like B22 bulb, are completely recyclable, they do not contain toxic and have no filaments or parts to melt substances.

How does a focus LED (light emitting diode) work? It is complicated, but in a nutshell the focus LED leverages the creation of electromagnetic energy through a diode prepared with specific elements that emit light by contact with an electric current.
