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
If that's not the reason for the shield, what is!
I don't know the exact rationale, but I can speculate. Maybe it helps
keep at least some moisture away from the socket. Maybe it helps
prevent bulb damage from minor hits. Maybe it just looks nice. Etc.
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.
I didn't even think about vandals breaking the bulbs!
Well that certainly makes sense. I did have a bulb that cracked once.
And no one goes in my back yard, let alone throw rocks at the light. I
sleep three feet from the light (through the window).
I assumed it was the rain when it was hot. But it's too late to
verify it was an exterior-rated bulb. I intended to buy that.
As to things living inside, hadn't thought about that either, because
mine isn't on much. If it were on 8 hours a night, or in a warmer
climate, yeah, wow.
If vandalism is that big a problem in your area, you need the floods
with the lexan bubbles around them. Or maybe somebody still makes the
wire cages, if you can find ones that fit your outside decor. Paint them
black, and they vanish pretty well.
Security 101- you don't put the lights on the building in high-risk
areas. You put them on poles, shining on the building, to eliminate
shadow zones people can hide in.
