Lighting devices are tools used to produce artificial light, enhancing visibility in various environments. Common types include light bulbs, LEDs, and fluorescent lamps. These devices can be found in homes, offices, and public spaces, serving both functional and decorative purposes. The technology behind lighting devices has evolved significantly over the years. Traditional incandescent bulbs have largely been replaced by more energy-efficient options like compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs). These modern devices not only consume less energy but also have longer lifespans, making them more environmentally friendly and cost-effective.
