It used to be difficult to sell a light bulb for more than $1. And
those would last a while.

*sigh* Here we go again. A brand name 100 watt incandescent lamp
draws 100 watts, costs about $1.50 and is designed to last 1000 hours.

When I moved here 15 years ago I replaced all my lighting with CFLs.
Purchased the mega pack from Sam's Club. Major name brand, though I
can't remember whether it was Sylvania or GE or maybe Lights of
America. Cost was about $3.50 each and they consume 13 watts (my
measurement).

I had a few failures at the 7 year mark but the majority of the lamps
are still going strong. The reduction in power consumption has paid
for the lamps many times over, not to mention eliminating changing
bulbs in inconvenient locations.

A few months ago I bought a couple of top-of-the-line Cree 100 watt
equivalent LED lamps. Cost was about $9 each. It also draws 13 watts
but the light output is twice that of a modern CFL. Read my
comparison testing here

Nowadays, they can sell $35 light bulbs, that last only a year, and
that could even get your house hacked.

That's not a light bulb. It's an Internet-connected microcomputer
with LEDs attached. I would not pay that but then I have no use for
an infinitely variable color lamp.

In summary, modern lamps draw a quarter the power of an incandescent
lamp, last many times longer, produce more than 4X the amount of light
and cost only modestly more than an incandescent lamp.

That's a huge win in my book.
