A light bulb is something you probably use daily, but have you ever considered how they work scientifically? Originally only a glass sphere with a filament inside (thanks, Thomas Edison!), light bulbs have since evolved into a wide variety of forms. But if you’re lost among the possibilities, don’t worry; we’ll explain everything from the different gases inside the glass to the forms of the light dimmable led flash you presumably use around the house.
First, there are incandescent bulbs.
Incandescent bulbs are constructed of glass and contain a gas like argon and a tungsten filament, and they were the first commercially available electric light bulbs when Thomas Edison and his coworkers invented them in the middle to late 19th century. The filament glows when an electric current is sent across it, producing light. Incandescent bulbs are not very energy efficient, but they cast a lovely glow on the skin (so use them in your bathroom vanities). The production of traditional 40- to 100-watt incandescent bulbs was banned by a law passed by Congress in 2007 to encourage more energy-efficient lighting. These days, incandescent bulbs can be found in a wide range of shapes, sizes, and wattages.
Fluorescent Lighting, Regular
The long, tubular shapes of fluorescent bulbs are instantly recognizable. Even while you’re more likely to see them in commercial settings like offices and stores than in residential ones like a garage, cellar, or workshop, you may find yourself in need of one. They are noted for their extended lifespan, typically several years, and for producing light by ionizing mercury vapor inside glass tubes using an electrical charge.
Third, a Compact Fluorescent Light (CFL)
Similar to incandescent bulbs, compact fluorescent light bulbs (CFLs) produce light when mercury gas inside the bulb is ionized, but their compact, twisted design makes them more practical for use in the home. Compared to traditional incandescent bulbs, CFLs have significant energy savings. Their bright illumination, higher price compared to incandescent bulbs despite their longer lifespan, and the presence of mercury makes them hazardous if broken.
To clarify: 4 Halogen
Halogen lights are intermediate between incandescent and fluorescent in terms of energy efficiency, and they provide artificial light that is most comparable to natural light, which is unquestionably better for your health. Similar to incandescent bulbs, these have a gas-filled glass bulb and an electrically energized tungsten filament to provide light. One key distinction is the gas used; incandescent bulbs are filled with argon and halogen ones with halogen. For this reason, they are best suited for occasional use, such as in floodlights outside of a garage or a lawn.
Fifth, a diode that emits light (LED)
LEDs are the most energy-efficient type of light bulb, but they work in a somewhat different way than their filament-burning counterparts. Semiconductors, or less conductive than metal but more conductive than insulators like rubber, are used to create this light. LEDs have a long lifespan (somewhere around a decade!), produce very little heat, and require much less energy to operate than traditional light bulbs. Place them anyplace in your home an incandescent bulb would go.
Smart light bulbs, number six
Now more than ever, even light bulbs may be “smart” and integrated into a larger network of devices across a home. Smart bulbs are Wi-Fi-enabled LED bulbs that can be controlled from afar with a mobile app or a virtual assistant like Amazon Alexa or Google Home. In most cases, the price tag is as high as you’d expect.
