Yeah, that does seem to be the marketing around them. I hadn’t realized, until this set of research, that the “enclosed fixture rating” was a thing - I’ve literally never thought about it before, because it’s a light bulb, they make less heat than incandescent, how can this be a problem? Well, because incandescents don’t care about the heat (and, actually, are more efficient in a very hot enclosure - less heat loss from the filament, and some of the super high efficiency “research lab” incandescents accomplish this by reflecting heat back).
It really varies based on the bulb.
But LEDs are definitely not the “spherical emitter” sort of thing an old bulb is.
The older Cree LEDs had a “stalk” in the middle, and emitted out to the sides fine, but had a dead spot straight out from the base.
The newer stuff has a flat panel with emitters at the base of the bulb, and relies on scattering in the opaque plastic globe. I should cut a few up and show them off. You can find plenty of teardowns, but I may as well hack up a few dead ones while I’m at it.
