Advantages of using LEDs are...
- LEDs produce more light per watt than incandescent bulbs; this is useful in battery powered or energy-saving devices.
- LEDs can emit light of an intended color without the use of color filters that traditional lighting methods require. This is more efficient and can lower initial costs.
- The solid package of an LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner.
- When used in applications where dimming is required, LEDs do not change their color tint as the current passing through them is lowered, unlike incandescent lamps, which turn yellow.
- LEDs are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out more quickly when cycled frequently, or HID lamps that require a long time before restarting.
- LEDs, being solid state components, are difficult to damage with external shock. Fluorescent and incandescent bulbs are easily broken if dropped on the ground.
- LEDs have an extremely long life span. These range from 50,000 – 100,000 as against CFLs which barely last beyond 1,000 – 2,000 hours and an incandescent bulb even lesser.
- LEDs light up very quickly. LEDs can be very small and are easily populated onto printed circuit boards.
- LEDs do not contain mercury, while compact fluorescent lamps do.
