What is a "Directly Controlled Luminaire," and why should I care?

et cetera...: Recent changes in the US National Electrical Code and UL standards have significantly changed the rules for emergency lighting in the US. We explore those changes in this blog.

For many years, emergency lighting in all kinds of facilities was accomplished with a familiar battery-powered device, known as “unit equipment.” Architects and designers gritted their teeth and dialed down their aesthetic expectations, since there was not much choice in code-compliant emergency lighting solutions except ugly, uglier, and ugliest.

This is such a strange article to me. I understand the dilemma with emergency lighting fixtures and signs being aesthetically displeasing and just plain ugly. But I don't understand the new regulations in terms of how they still stay "emergency lighting" it seems to me that any light reaching the correct standards could be used in this manner. For me the reason these things were always so ugly was because they stood out in almost every space that they were in and made it easily found. But hey if they want to encourage people to use them and use them more often in spaces to make them safer then I'm all for it. It's really interesting that a company like ETC is jumping in on this as will the Par lineup isn't something that I would have ever traditionally associated with being used as an emergency light fixture but who knows what applications and uses ETC has planned for their fixtures going forward and really the rest of the industry for that matter I guess.
