LED bulbs in recessed cans/enclosed fixtures

I have a couple recessed cans (marked Type IC) that I'm replacing bulbs in, but I've run across two questions.

1) The recessed fixture says max 40W A19 bulb. That 40W clearly refers to incandescent, so a 60W-equivalent, 8.5W actual draw LED is good to go, right?

2) I have LED bulbs that state "suitable for enclosed fixtures" on the front of the box. But in the fine print on the back of the box, it says "use in enclosed fixtures may shorten bulb life." I've always heard that "suitable for enclosed fixtures" meant it could be used in enclosed fixtures without any problems, but shortened life sounds like a problem. Am I misunderstanding? Do I need to look for a different bulb?

Correct on both counts.
Correct, any enclosed fixture will shorten the lifespan of an LED bulb. The electronic is what gets affected from the heat that can't be dissipated. Nothing unsafe about it. And it's not a problem.
Also an open globe using an LED bulb will last a bit longer if the open globe points up as opposed down, trapping heat near the electronics of the ballast.
