LEDs have many advantages over incandescent and florescent light sources, above all due to their lower energy consumption, longer lifetime, smaller size, durability, resistance to vibrations and reduced heat emission. They do not contain mercury (which is highly poisonous to the environment); compared to florescent technology. They do not create high magnetic fields like magnetic induction technology, which create higher residual radiation towards human beings. They have a better chromatic production index compared to other types of lamps and they reduce noise on power lines. They are specially designed to be used with photovoltaic systems (solar panels). Compared to any other current technology, they are not affected by intermittent switching on and off (this means that they can work as strobe lighting) and this does not reduce their average lifetime. They are especially designed for anti-explosion systems, as they have a resistant material and in the majority of colours (except for blue LEDs), they offer a high level of reliability and duration, a more precise electric current, due to their electronic system, for working with alternating voltage and require increasingly more efficient heat sinks.
LEDs offer the advantage of having a very short on/off time compared to high power lamps, such as high intensity sodium-vapour lamps, metal additives, halide or halogen and other systems that use incandescent technology.
