Anyway, this meeting concerns lighting engineers, those who design lighting fixtures and systems. Their main concern might well be safety, efficiency, and security. Indeed, the first objection to changing lighting systems specs is usually safety and security, and in this a little education changes a lot of minds.

Don't talk about energy conservation

Why not? Modern light fixtures with low light spillage are more efficient and do save power. The idea is to rip out the old bad fixtures when it comes replacement time and replace them with good new ones and not cost anything, or to require modern light fixtures with low light spillage on new construction.

Do you, personally, really care about the energy efficiency of light fixtures?

If so, why?

This is the way to do it. Don't throw away a serviceable system until its ready for replacement anyway, then go with the new stuff.

I've been doing that with CF lamps around the house and outside, but for some reason my wife hates them (they need a little warm-up time and she thinks they're dingy during that time).

The freeway interchange near my house was just rebuilt and the highway dept. used those downward-reflected fixtures on the tall poles. Man, it makes a difference! Plenty of light on the ground and almost no sky glare. Its a really good way to go for new constrcution and renovation.
