In another thread, it was mentioned that CFLs and LEDs

last longer than incandescent bulbs.

We all know incandescent bulbs fail due to the filaments

being made so thin that they oxidize and burn up, over time.

But, what causes CFL bulbs to fail?

And, what causes LED bulbs to fail?

I remember thirty years ago, you wouldn’t even think about breaking a
fluorescent lamp while replacing it. In fact you hardly ever had to
replace them. Now they make the class thinner than an eggshell and if
you’re not VERY careful it breaks before you even finish putting it
on, and even if you manage to put it on, the glass doesn’t last long
once it gets hot. Glass is mostly made of silica which is cheap, so
it’s not that the Chinese are saving money by making it thinner and
if it’s not to save money then the only reason they would have to do
so would be so you keep having to replace them and buy more.

Shipping costs are weight sensitive.
