Some outdoor floodlights have shields around the bulbs now.

Is that so that when they are on, and hot, and it rains on them, they
won't crack? That's what I figure, but if so, why did it take so
many years to provide these shields and why do some floods still not
have them.

If that's not the reason for the shield, what is!

Thanks.

Looks and security would be my guess.

I just bought a 2 bulb motion detector model and I paid $5 more for the
model that shielded the sides of the bulbs because I think it will be more
difficult for vandals to break the bulbs.

Exterior rated bulbs are designed to handle the cold rain on the hot bulb.
