Mark,
The DOE has a program, Lighting Facts, that has most manufacturers
putting a Lighting Facts label on the box and the marketing, just like
they do with water heaters, lists the CRI, color temps, etc. They are
pretty good at testing, enforcing, and publishing the data.

On swapping T5 to LED, a few years back I lit a garage with mostly T5HO
and some spots. It's a large residential garage for the client's cars,
large enough to have a full time staff of 2 to 3, depending. He asked
about LED recently and I advised sticking with the T5HO, he can afford
to swap to LED but the hassle of moving the cars and going through the
whole process, and for what?
Here's a couple images, it's lit to about 45 footcandles.
