Q: My home is about 20 years old. My problem is with the lights in the kitchen. Sometimes they work and sometimes they don’t. When I turn on the switch, the light flickers or just partially lights. I ...

Electronic ballasts used in fluorescent lighting systems can experience high failure rates, due to the fact that the ballast manufacturer may not have considered all failure mechanisms or provided ...

Fluorescent light fixtures are more efficient and cheaper to run than incandescents. But some fluorescent fixtures buzz or hum, and they take a long time to start when temperatures fall much below ...

Fluorescent lights are more efficient than incandescent ones, but also more complicated. As a result, simply replacing the bulb-actually a tube-when a fluorescent light develops problems will not ...

In part 1 we discussed rectifying the ballast AC current to DC and we showed an open load protection circuit. Direct replacement of fluorescent tubes with LED assemblies can lead to uneven lighting.

Aided by a new full-bridge controller, a popular electronic HID ballast topology manages lamp operation, while enhancing lamp safety. Tom Ribarich, Director, Lighting IC Design Center, International ...

A new device from the United States could make fluorescent lighting even more efficient than it already is. Standard fluorescent lights save four times more energy than an ordinary light bulb, but ...

To comply with new laws on reducing energy usage, fluorescent and HID lighting systems — both examples of arc discharge lamps — have become more complex and varied in their performance. To understand ...

Some goes to a switch (thus shouldn't have collisions anyway), but in either case it all works fine -- 10mb for the hub, 100mb for the switch, no problem.<BR><BR>My working hypothesis is that it works ...

Q: The kitchen of my 1987 house has fluorescent tubes in the ceiling, which is dropped down 5½ inches so acrylic panels covering the lights look like part of the ceiling. I hate the quality of the ...
