LED lights that are built into the fixture are referred to as integrated LED bulbs. They have a light source as well as an exterior fixture. Integrated LEDs often connect to a mains voltage without the need for any other components. This means that they can be used in any standard socket. They also last longer than traditional incandescent or fluorescent lamps. An integrated LED lamp works by using electricity to create light inside the lamp, which is then emitted through the lens or shell of the lamp. These lenses can be made out of clear plastic or glass and usually colorize the light being produced by the lamp. There are two types of integrated LED lamps: those that use polymers as their primary material and those that use ceramics. Polymer-based lamps are more affordable but will likely not last as long as ceramic-based lamps. The best option here is to choose an integrated LED lamp that uses ceramics so that you get quality lighting along with cost efficiency. The second type of integrated LED lamp uses ceramics for its casing and its circuit board, which houses the LED chip(s). These lamps are more expensive up front but they will last much longer than polymer-based lamps. It is important to note that these lamps cannot be replaced once they have been installed.
