Typical Uses and Applications

Dimming electronic fluorescent ballasts can be accomplished through either 0-10V or Phase-Control analog technologies, or the digital DALI protocol. Any of these can be used in most dimming situations, but each has its own unique benefits.

Today, the most commonly used technologies are analog. Typically, if the application is energy-management in nature, 0-10V is more likely to be used. This scenario allows the user to tie the lighting together with occupancy or daylight sensors, building management systems or manual dimming controls.

If the applications is part of an architectural lighting scheme, such as dimming a conference room or an individual office, Phase-Control technology may be most appropriate. Here, the stand-alone dimming ballast with only a two wire connection allows for simple, cost-effective retrofits and excellent single location control.

An alternate technology, digital DALI, is best suited where a higher degree of individual lamp addressibility is required or the flexibility to easily provide for future lighting changes is desired.
