A light source consisting of a long glass tube containing mercury in a partial vacuum. Available in many lengths and several diameters, the tube is lined with a fluorescent phosphor. When the ...

When your fluorescent light flickers or makes a loud and annoying hum, a degrading ballast could be the cause. Replacing a ballast is easier than you think, but ballasts can be expensive ...

In addition to sunlight, ultraviolet rays are also given off by several different forms of indoor lighting, including compact fluorescent lamps (CFL’s). CFL’s are commonly long, cylinder shaped and ...

Fluorescent probes are molecules that absorb light of a specific wavelength and emit light of a different, typically longer, wavelength (a process known as fluorescence), and are used to study ...

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 ...

Thus far, the best tools for imaging in live, whole animals have been far-red fluorescent proteins because both autofluorescence and light absorption by the animal's tissue are minimized at the ...

VFDs — vacuum fluorescent displays — have a distinctive look, and [Anthony Francis-Jones] is generally fascinated with retro displays. So, it makes sense that he’d build a VFD ...

The shift from fluorescent lamps to more energy-efficient light-emitting diodes is expected to have a decarbonizing effect. If LEDs replace fluorescent lamps by 2027, carbon dioxide emissions can ...
