Fluorescent tubes are filled with mercury gas and can shatter into very small pieces. If that happens, the Environment Protection Agency recommends airing out the location of the breakage, then picking up the pieces with a damp paper cloth. The pieces must be sealed in a plastic bag then thro...
When it comes to appearance, LED tubes look exactly like fluorescents. However, they are very different. First, LED is a mercury-free lighting solution. There are no costly recycling fees associated with LED lights. And you will never have to worry about a tube dropping and contaminating an ...
In addition to the tubes commonly used for fluorescent lighting, this type of light also requires something called a ballast. A ballast is a long, rectangular box that controls and regulates the output of the fluorescent lights. Many different types of ballasts exist and you can buy one that ...
The crystals convert the gamma rays, emitted from the patient, to photons of light, and the photomultiplier tubes convert and amplify the photons to electrical signals. These electrical signals are then processed by the computer to generate images. The table is then moved, and the process is re...
So, in short, fluorescent lights make their energy in a three-step process: Electrodes take electrical energy from the power supply and generate moving electrons. The moving electrons collide with mercury atoms in the tubes to make ultraviolet light. The white phosphor coating of the tubes convert...

In reality, these tubes are coiled in the shape of a snail shell, but it's easier to understand what's going on if you imagine them stretched out. It's also clearer if we treat two of the tubes, the scala vestibuli and the scala media, as one chamber. The membrane between these ...
No-one really knows what light is like, but scientists have settled on the idea that it has a sort of split personality. They like to call this wave-particle duality, but the basic idea is much simpler than it sounds. Sometimes light behaves like a train of waves—much like waves ...
The fluorescent lighting that for years relied on fluorescent tubes, and more recently on LED lamps, converts UV or blue light into longer wavelengths to create a white-light output. Measurement of fluorescence is another area in which single-photon detection enables improved capabilities, particularl...
Most high-end LCD screens are called transmissive because the light source comes from behind the screen. That light is generated by a small fluorescent tube attached to alight guidethat directs the light forward toward the LCD panel. When the light reaches the LCD panel, it must first pass ...
