The DALI light control interface provides a simple two wire low voltage control bus to allow the individual addressing and control of individual light fittings. For existing buildings, the requirements to install/cable in photo sensors and the lighting control bus, makes this approach impractical, ...
A lamp that produces light by exciting the atoms of a mixture of argon gas and mercury vapor with electric current. Ultraviolet rays produced by the excited atoms strike a phosphor coating on the interior surface of the bulb, causing it to emit visible light. Fluorescent lamps are much more ...
2-wire control is a line-voltage phase-control dimming method. The ballast receives the dimming signal through the Dimmed Hot wire. Intended for small-scale retrofit applications, the 2-wire control method is often the easiest way to implement dimming in existing fluorescent fixtures. Lutron balla...
Magnetic ballasts will be allowed for other fluorescent lamps and HID lamps. As fluorescent lamps approach the end of their service life, the paste on the electrode coils become depleted. This generally occurs at one electrode first and the power increases dramatically in an attempt to maintain ...
DALI was created as a means to digitally control and dim ballasts in fluorescent lighting fixtures using a simple two-wire connection that can be wired as a daisy chain using inexpensive wire and, in many cases, can utilize the same conduits as the main electrical wiring. New Applications for...

Causes of Flickering Fluorescent Light Fixture Properly-functioning fluorescent lights should not produce a flickering that is noticeable. Standards for ballasts typically state: Ballasts shall operate lamps with no visible flicker (<3% flicker index). ...
Electronic ballasts generate a high-frequency supply to the lamp (typically 30 kHz). At this frequency the normally bulky wire wound ballast can be made small and light. The ballast can be very efficient, but the generation of high frequency can give rise to conducted and radiated interference...
Ballast-type test:Determine if ballast is electronic or magnetic without taking fixture apart–identify energy wasting ballasts Other useful capabilities: Built to last, easy to maintain. Features a rugged, extendable all metal test rod that can be easily replaced should the need arise....
the resistors770collectively provide a simulation resistance and/or impedance that mimics the fluorescent lighting element's resistance and/or impedance, which is monitored by the ballast715. Modern ballasts are typically designed with light source identification capabilities which allows them to monitor re...
