They are very efficient devices, as almost no heat is generated in the process, leading to much longer battery life. ![]() 'Standard' LED's are low current devices, which produce relatively low levels of illumination, and are used as indicators rather than light sources. You can use a standard LED: as a 'power-on' indicator to show that a system is currently connected to a power supply; as an 'armed' indicator to show that some function of the system is active; as a sequence indicator, to show which stage of a sequence of operations is currently under way; as a simple test instrument to show whether an output of the system under development is at a high or low voltage, (logic 1 or logic 0,) during the testing stage. LED's are available in a wide range of formats, from pin-point sized single LED's, to arrays of ultra-bright LED's, used in message display panels, and traffic lights. ![]() (:nl:)(:table style="clear:both":)
