The world of lighting has been dominated by the incandescent bulb for as long as most us can remember. While they have undergone some improvements, they remain very inefficient, and less than 10% of the energy consumed by them is converted into useful light. The energy which they waste is evident in the amount of heat that they produce, and the heat is one of the reasons that they burn out fairly quickly.

With energy and environmental concerns almost certain to grow, a more efficient bulb is a necessity. CFL bulbs are a lot more efficient, and are already replacing incandescent bulbs in many uses, however, they have some drawbacks, such has taking approximately a minute to reach their full brightness.

LED bulbs are a much better alternative in the long-term. Their only major disadvantage is how much they cost, but their price will come down as they become more widely used. Their high level of efficiency is due to their unique, solid-state design and way of producing light.

LED lighting works with the passage of electrons through a semiconductor material, which consists of both negatively and positively charged components. The positive layer has small openings that free electrons from the negative component can pass through.

Since they are so much more efficient, they run at a lower temperature. This reduces the risk of being burned by touching a hot bulb, and also saves on cooling costs in the summer, since the bulbs are not producing so much heat.

Unlike CFL bulbs, which take a while to reach their full brightness, LED bulbs come on within a second or two. They are also able to be dimmed, can produce lighting in any color without filters, and create a highly directional light, that is great for task lighting.
