Instead a very different type of electronic component ruled the roost, the vaccum tube. A set of electrodes in an evacuated glass envelope whose electrical properties depended on the modulation of ...

Do you love Nixie Tubes? Upset that they aren’t really manufactured anymore, and the cost of old ones is rising? Why not make your own? That’s exactly what [Dalibor] of the Czech Republic is ...

A website touting the Sylvania SilverStar headlight bulb says it provides "up to 30 percent" greater visibility down the road. That sounds impressive until you read the fine print: "compared with ...

For a time, however, it appeared that fluorescent protein engineering had hit a 'yellow' wall in efforts to red-shift fluorescence emission. Fortuitously, this barrier had already been surmounted ...

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 ...

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 ...

and seal the ends of the tubes with masking tape. Keep fluorescent light tubes from breaking before you use it. It'll fit ...
