...and I like the fact that they don’t take 90% of the energy they use and turn it into heat.

This is a recurring theme in the reasons people from southern latitudes like them.

For those of us practically on the Canadian Border, though, days are considerably shorter in the winter, the time of the year the "waste" heat is a welcome addition to our homes, and much longer in the summer, (IOW, who needs to turn the lights on?) in the summer. The 'extra heat' isn't wasted here, and does not work against the Air Conditioning when we do run it.

The only problem is getting the kids to bed at 11:00 PM in July while the sun is still shining.

("But Papa! It isn't even dark outside!")

So, as usual, we are stuck with a one-size-fits-all solution for a problem we did not have. YMMV

I can see at least it isn’t wasted. But 10% efficiency of anything kind of grates on me. Either be a heater, or be a light. It ain’t a fire.
