There are many different types of lights available on the market, and each type has its advantages and disadvantages. When it comes to light Bulbs, the options are endless. You could go with the popular incandescent bulb or, perhaps, a fluorescent or halogen bulb. There are also energy-efficient options such as Compact Fluorescent (CFL) and Light Emitting Diode (LED) bulbs.

Recently, however, another type of light has been developing in popularity. Oled is an LED which has an emissive electroluminescent layer made of an organic compound that puts out light as a response to electric currents. OLEDs are often used in television screens, computer monitors, cell phones, and handheld game consoles. Research has also been done into developing solid-state lighting with white OLED devices.
