Today's design engineers are faced with new challenges when it comes to designing fluorescent or HID electronic ballast applications. In addition to the usual cost, reliability and longevity pressures ...

With all of the excitement surrounding LEDs these days, one might say high-intensity discharge (HID) lamps are out of the limelight. But though LEDs get most of the headlines, HID sources are still ...

The highly efficient Lighting Ballast Transformer Series from Innovative Power, Inc., offer superior performance, excellent reliability and rugged construction for aerospace, industrial and commercial ...

A ballast for a fluorescent lamp has two primary functions: Provide high initial voltage to start the lamp; and regulate lamp current during operation. Common electronic ballasts convert 60-Hz line ...

Electronic ballasts used in fluorescent lighting systems can experience high failure rates, resulting from end-of-life (EOL) issues. The IEC 61347-2-3 standard specifies three tests to simulate the ...

If a lighting ballast fails, do you change it out hot? That's a fairly common practice, but you can get electrocuted by 277V just as surely as from a higher voltage. If you're on a ladder, the fall ...

Researchers are developing a high-resolution tracking system that uses PDAs and audio directions to guide patients around hospital wards. The system also helps rehabilitate those with traumatic brain ...

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 ...
