Do You Agree with the Ban on Incandescent Light Bulbs? DEBATEYES PEOPLE give out about the EU meddling in our affairs, but sometimes the suits get it spot on. This light bulb ban is a victory for green campaigners and, more importantly, for the planet....
Many people’s hard work led to the light bulb’s invention, which has changed our lives greatly.The first light bulbs are known as incandescent light bulbs (白炽灯泡). Today, we use energy-saving bulbs that are better for the environment. An American engineer invented the first LED in ...
They do cost more than CFLs and incandescents, but equivalent LED bulbs can last at least 30,000 hours compared to 1,000 hours for incandescent bulbs, or 8,000 to 10,000 hours for CFLs. 7. Live Energy Wise Make your home more energy efficient (and save money). Your home's windows...

Since LEDs aresolid-statecomponents, they create “cold” light instead of the “warm” light of incandescent bulbs. Most of the energy generated from anincandescent light is not light, but heat. In anLED, however, almost all energy is emitted as light waves. That is one reason that LEDs...
Photo: LEDs are much smaller than lamp bulbs and use a fraction as much energy. They are particularly suitable for use in instrument panels, which have to be lit up for hours at a time. Put many diodes together and you can make as much light as a conventional bulb and still save ...
So what's a tungsten light source? Tungsten or Tungsten Halogen lights are incandescent filament bulbs which are common in homes and offices but have been being slowly replaced with longer lasting, more reliable bulbs. What sets these bulbs apart is that they take advantage of what is known as...
You can replace xenon lights with LEDs. ... So overall, xenon lights are pretty great. But they could be better. While xenon lights are more efficient, longer lasting, more durable, and cooler than halogen and regular incandescent light bulbs, they still don't beat LEDs. ...
the cause of this is not the light itself, but the color temperature of the light. The ultraviolet light emitted by traditional incandescent light bulbs attracts insects. LED lights, on the other hand, emit very little UV light, but they do emit blue light, which insects are attracted to....
