Again, that only applies to brand new buildings, which accounts for a very small % of lighting installs. For the vast majority of theatres and schools, all of that infrastructure is a sunk cost, and what they face instead is having to replace an inventory of incadescents with fixtures that cost over 4x more (and the incandescents work just fine, only now [theoretically] lamps are no longer available for them). Yes, you're right, the replacement doesn't have to be 1-to-1, as one fixture will do the job of several, but it is still a cost that most not-for-profits simply can't afford
I believe that much - the majority - of new lighting equipment sold is to new schools, not existing schools and other. As I have noted on numerous occasions, in new build, now it's a wash in cost between all LED and all incandescent, with LED becoming less expensive soon.
As noted, in new build LED is same coat or less than incandescent, and I suspect the majority of lighting sales is LED to new build projects. You only have to look at the near unavailability of new incandescents to get that. The cost of labor and infrastructure for incandescent is 3 to 4 times that of LED. I've been averaging 6 or more new builds a year for several years and am certain. And if in each of those is 75-100 fixtures more or less. How many are existing schools buying? Maybe 1 of every 10 schools buys a dozen fixtures?

And it's safer.
Sorry, I posted this before seeing many more posts on next page. But yes, the infrastructure for incandescent is several times the cost of the fixtures, so quite easy to see LED is less expensive in new build.
. I was simply stating that in new build LED makes sense. As I have stated before changing over makes no economic sense. Just having feeders, dimmer space, HVAC, and many branch circuits in place tips it way over to incandescent.That doesn't address the majority of spaces that are retrofitting
