HOW LED LIGHTS WORK

If you need a bright, long-lasting light that is also energy-efficient, light-emitting diodes (LEDs) are the way to go. These bulbs have seen vast improvements in technology that have made them an affordable choice for tasks, homes, and hobbies that need clear, clean light. LED lights don’t work in the same was as plain filament bulbs, however, which contributes to the LEDs’ longevity.

When you look inside an LED bulb, you’ll see several smaller bulb-like structures. These are semiconductors that produce light. The materials out of which LED semiconductors are made can change the type and color of light given off by the bulb. The light you see coming out of LED lights is electromagnetic radiation. This is produced when electrons move along the semiconductor.

These semiconductors are much tougher than the tungsten filaments you find in traditional incandescent bulbs, and they don’t draw nearly as much power as the filaments in halogen bulbs. A big advantage to using LEDs of compact fluorescent lights is that the LEDs contain no mercury, meaning you don’t need to take special precautions when tossing an old LED that no longer works.

LEDs are suitable for everything from small fairy lights to large off-road light bars. They are particulary well-suited to spotlight functions, so if you need work lights (either small task lights or bright spotlights) or driving lights that won’t burn out on you when you’re in the middle of nowhere, LEDs are what you want.
