The Digital Addressable Lighting Interface (DALI) protocol, has been hailed as providing the ultimate in flexibility in control of fluorescent lighting systems. If you are new to DALI, you should know that it is not a product. Instead, it is a standard protocol, already adopted by a number of manufacturers in Europe and Asia, defining how ballasts have to perform. With DALI, dimming -- which was traditionally restricted to architectural lighting, daylight harvesting and conference rooms -- can now be deployed across the entire facility to achieve high energy savings (30-60% including ballast-lamp efficiency) as well as extraordinary flexibility, user control and maintenance benefits. |
