Top Light Bulbs
Whether you’ve stepped foot along a busy street at night, watched cars pass outside your window, or simply opened the fridge to look for something to eat at 3 am, you’re sure to have come into contact with a light bulb at some point in your day to day life.
In technical terms, a light bulb is an invention that produces light when connected to a powering circuit. This can include a wide range of lights from the fluorescent lights of school hallways to the halogen lights in the front of your SUV. But how well do you know the ins and outs of what makes up these amazing pieces of technology we take for granted?

What is a Light Bulb?
While officially patented by Thomas Edison, the invention of the lightbulb predates his version by about seventy years with the invention of the arc lamp by Humphrey Davey in 1802. Simply made of a cotton filament that would glow when powered, this lamp was impressive but impractical. The light produced was too vibrant and the exposed filament posed a serious fire hazard. Further developments were made over the following years, including treating the cotton filament to prevent smoke and encasing the filament in a glass orb filled with nitrogen to produce a stronger flame.
While many individuals contributed on the invention of the light bulb we see today; Edison’s team is credited with perfecting the vacuum seal in modern light bulbs and spearheaded the use of carbonized bamboo filament to produce a longer-lasting light bulb. But we’ve come a long way from the early days of incandescent bulbs.
Types of Light BulbsWhile modern lightbulbs come in all shapes and sizes, most mass-produced version fall into one of four categories: incandescent, compact fluorescent (CFLs), Halogen, and LED bulbs. The first category, incandescent, is the same kind of bulb invented by Edison. By heating up a filament the bulb produces a steady, sustainable source of light. CFLs, on the other hand, superheat mercury to produce a tone controlled, cooler light source that is more cost and energy effective than their forerunners. These are the curly lights that you find in most lamp fixtures. Halogen bulbs, as well as Krypton and Xenon bulbs, work by heating up a filament or other conductor within a bulb that is filled with a type of gas. The type and coloration of the light produced comes from these different gases and how they react to the heat produced by the filament. While Krypton lights produce a very clear, white light, halogen bulbs are more yellow in nature.
The final type of lightbulb is the LED. Known for being more environmentally friendly and economically conservative than their counterparts, these light-emitting diodes take advantage of electroluminescence to produce a vibrant, often colorful light. Since these forms of light produce a very minimal amount of heat and can be made incredibly small, they are used in electronics and remote controls, as well as headlights and flashlights.
With so many different light bulbs to chose from, finding the right source of light for your home, office, work space, or yard can seem challenging. Make sure to keep in mind the different strengths and cost options available when looking to shed a little light on your home.
