They don’t show the labels because the brand didn’t pay. If you see a label with a brand on it they probably paid.
For a cooking show it’s probably not going to be worth the time and effort to get a contract in place for every ingredient, so you only see it occasionally.

I almost always recommend the Phillips Ultra Definition bulbs, but they only do 2700k and 5000k. If you want something in between you might get stuck paying quite a bit more for a specialty one.
