Lost in Translation: Where People Get DALI Wrong (3)

In previous DALI myth busting episodes I covered the DALI bus polarity and DALI application controllers. This time we are going to the heart of it all: what is DALI-2 (and what it is not).

This, on one hand, is the easiest one. On the other hand it is very rarely that people really know and understand what the DALI-2 logo means.

There are many myths (and unfortunately many being repeated by AI assistants). Like : DALI-2 delivers device power over the DALI bus. Or control devices (see the previous post for details) are only standardized by DALI-2. This is all not accurate.

As a matter of fact we could say there is no such thing as DALI-2. At least not a DALI-2 specification. Because a DALI-2 logo on a product means just one thing: the product passed DALI tests and has been certified. Practically this means the DALI organization made the best effort to ensure this product follows the specification and will interoperate nicely with other products that carry DALI-2 logo.

DALI-2 does not say anything about what the product can do. Can it provide power to the DALI bus? Don't know. Can in be powered from the bus? Don't know. And so on. Anyone who wants to learn about the specifics of any DALI-2 product must go to the DALI Alliance Product Database and locate the product there. The database then shows what DALI Parts the product implements).
