LED bulbs are largely a scam for bulb makers to stuff more money into
their pockets.

Here's some realistic numbers:  I replace a 40 W incandescent bulb
with a LED one.  Aldi middle isle, 2 euros.  Residental power is
about 0.40 euros/kWh here, so the bulb will have paid for itself once
it has saved 2/0.40 = 5 kWh.  It produces the same illumination at
1/10 of the power of the incandescent, so it saves 40 - 40/10 = 36 W.
5000 Wh / 36 W = 140 h, so if used one hour each day, it will have
paid for itself in under five months.  If it eventually dies after
10,000 hours instead of a promised 30,000, so be it.

You can plug in numbers that are applicable to your situation and
in your part of the world.
