Current light bulb technology has greatly improved over older incandescent bulb technology. Newer LED and xenon bulbs produce a more light while using less energy. The use of LED and xenon bulbs in flashlights and car headlights is common. You also can use LED and xenon bulbs in a variety of places, including under-cabinet lights, display lights and decorative lighting for holidays.
Light-emitting diode, or LED, lights use about one-seventh the energy of an incandescent bulb and can last up to 100,000 hours per bulb, according to G. Miller and Scott Spoolman in “Environmental Science Problems, Concepts and Solutions.” LED lights use a diode that is about one-fourth of an inch to convert electricity into light, according to the website toolbase.
Advantages of LED
LED lights are small, and you can group them together to concentrate light. LED lights are good in areas that need bright, direct lighting, such as displaying art or under kitchen cabinets to highlight counter space. You can use LED lights in high-traffic areas because of their durability. You also can use them in waterproof devices, according to toolbase.
Xenon technology uses the noble gas xenon to produce light that is very close to natural sunlight. Xenon headlights in cars improve visibility because the lights illuminate a broader area in front of the car than a traditional headlight. There are a variety of other uses for xenon lights, ranging from operating rooms to airport signal lights, because xenon bulbs last a long time, according to the Xenon Corporation.
Advantages of Xenon
The light produced by xenon gas technology is very bright, making it especially good for places like hospital operating rooms. It also is very close to natural light. Xenon gas lights can last from 6,000 to 20,000 hours per bulb, according to the website lighting-fixtures-tips-designs.
Both xenon and LED lights have disadvantages. Xenon lights can explode when they are old, according to the website FilmTech. Xenon headlights can make it difficult for oncoming drivers to see, according to USA Today. LED lights produce directional light, but they don't create enough light to light a room. Xenon bulbs also are much more expensive than either LED or traditional lights.
