Compact Fluorescent Lights: Think of a normal florescent light tube, but curled up to fit the shape of a standard light bulb. The best CFLs last 10 times as long and use a quarter of the energy of old incandescent bulbs, according to the federal Department of Energy. The drawbacks of CFLs are that they can be damaged if they are turned on and off too frequently, and they don't work well in the cold so their outdoor utility is limited.

Light Emitting Diodes: Traditionally, LEDs were for power lights on appliances and other limited uses, but advances in technology have greatly expanded their utility, and there are now numerous options for LED light bulbs available to consumers. LEDs are a fantastic value: they use only about 25 percent of the energy of standard light bulbs and can last up to 25 times as long.

Halogen Incandescents: Halogen bulbs are a twist on the old-fashioned incandescent bulbs. They function in essentially the same manner, except the glass globe is filled with halogen gas, which amplifies the light and therefore decreases the amount of electricity needed, hiking its efficiency rating. They aren't as stingy with energy as CFL or LED lights, but work well for outdoor spotlighting.

While modern bulbs cost more to buy than the incandescents you were accustomed to, their increased longevity and efficiency actually lead to big savings in the long run.

LEDs are at the forefront of light industry discussion because they are such a gamechanger when it comes to energy efficiency and lifespan. But how do recent developments to LED technology affect the everyday consumer? What’s the simplest way to navigate this uncharted territory when shopping for LED light bulbs? The very recent availability of an LED replacement for the common household incandescent lamp has created a world of new potential, and along with it a whole new set of standards. In this post, we will be discussing the various ways to distinguish between the different LED options.

There is a very dangerous myth floating around, one which could actually result in severe injury and even death – “Electricity always follows the path of least resistance”. This is one of those myths that results from a general fact being blown way out of proportion.

Forget colleges and engineering schools, most high school students learn that electricity does behave this way, as a part of the basics of electricity and resistances. Worryingly, this myth isn’t just stated as a fact, it’s a commonly followed practice in many electrical circuit designs, especially when it comes to grounding.

Walk into any industrial plant that uses motors or pumps and you’ll find they’re all connected to ground rods. Ask anyone why that’s done and you’ll likely get the same response everywhere (even from the people in charge of the electrical maintenance) – It’s to eliminate the potential differences.
