456 and 720 are two varieties of LEDs: Spacers, Standoffs. In general, spacers and standoffs refer to the same thing—elements used to space two pieces of a material apart from each other, such as two circuit boards or a window frame and a refrigerator door. They come in various shapes, sizes, and materials to fit the different needs of projects. Some of the most common used materials that Standoffs and Spacers are made of are steel, aluminum, stainless steel, brass, and plastic.

In the context of LEDs, spacers and standoffs also refer to elements that space yellow-green LEDs out from their surroundings. This is especially useful in applications where the LED needs to be clearly visible, such as a warning signal, or a lighted switch. The space between the LEDs and the surrounding material should be large enough so that the LED lighting is not obscured and still visible.

456 and 720 LEDs are two such types, and are mainly used for aesthetic reasons. They are especially used in computer cases where the LED should not be obstructing the beauty of the case. The LED is placed in between two pieces of a material, and ensures that the light from the LED is clearly visible. Similarly, these LEDs are also used in lighting fixtures, to make sure that the fixture looks neat and clearly lit.

In terms of working principle, 456 and 720 LEDs can often also be understood as being used in circuits. In this case, applying a certain electrical voltage to the LED will cause it to emit light thanks to quantum-mechanical effects. The 456 and 720 LEDs are especially chosen for electrical applications because of their yellow-green color, which is well-suited for use in warning systems. In addition, a large number of them can be used in a circuit without the resulting wiring becoming too complex.

In conclusion, 456 and 720 LEDs, which are types of standoffs and spacers, are often used for aesthetic purposes. They are placed in between two pieces of material so that the LED lighting is not obscured and remains visible. Similarly, these LEDs are also used in circuits and apply a certain electrical voltage to the LED in order to cause it to emit light. Therefore, 456 and 720 LEDs are used for both aesthetic and electrical applications.
