Like CFL bulbs, fluorescent light bulbs — those long glass tubes — also contain mercury and require careful handling when replacing. Some home centers offer recycling services for these bulbs ...

Or, did we not know enough about LED aging to predict the true useful life of a bulb? I put these questions to the test. Join me after the break ... be available in the near future?

Recycling facilities collect glass and mercury from thrown-away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths ...

Available in many lengths and several diameters, the tube is lined with a fluorescent phosphor. When the mercury is excited by electricity, it emits ultraviolet (UV) light, which causes the ...

In another video, he goes over the wiring of a fluorescent starter to create a flickering effect with an incandescent light bulb. A fluorescent starter works because the current heats up a gas ...

Recycling plant workers such as Hamed also face health risks. They are not provided with any safety equipment, even though they work near a furnace that has a temperature of 660 o C. Hamed, for ...

Fluorescent lamps are high-efficiency lamps that use electrical discharge through low-pressure mercury vapor to produce ultraviolet (UV) energy, which is then transformed into visible light. The UV ...

For decades, LEDs have been used as indicator lights on myriad products; however, starting in the 2000s, they began to replace incandescent, halogen and CFL fluorescent bulbs. LEDs draw ...

They hold light bulbs and make electrical contact to provide a bulb with power. Lampholders are used with most light sources for incandescent, fluorescent, and compact fluorescent lamps (CFL).

Remember, LED bulbs are electronic devices. Just like with your phone or your laptop, it isn't good to let them overheat. That's why it's fine to stick with incandescent, fluorescent and halogen ...

Here we introduce near-infrared fluorescent dye-labeled peptides as sensitive tracer molecules for tumor targeting. We describe the in vivo application of a peptide conjugate coupled to a cyanine ...
