LED lighting as an option has gained traction and increasing popularity since it was first introduced as a lighting option. There are many practical reasons for this. LED lights work via a microchip rather than a filament. The distinction makes them many times more efficient than regular incandescent bulbs. LED bulbs also last a lot longer. It’s not unreasonable to expect the lifespan of an LED bulb to exceed that of a regular bulb by as much as four times. LED lights are more expensive to manufacture and therefore more costly to buy. However, the greater longevity and efficiency usually compensate for the added cost. The use of LED lights is a greener choice than conventional bulbs, because they use less power and have no mercury. One potential downside is that LED lights don’t burn out quickly, as is the norm with conventional bulbs. Towards the end of their life they start to dim.
- In a light emitting diode (LED), the electrical current passes through a microchip rather than a filament.
- LED lights are better for the environment because they consume less power and are mercury-free.
- LED lights don’t abruptly burn out, instead, they gradually become dimmer.
