How did Michael Jackson's "lightening" of his skin change the world?

Andy comments:
I have some LED night lights that draw 0.4 watts that I leave on
all the time. Each light costs about 35 cents a year to operate
24 hours a day. Previously I used the 7 watt night lights which
burn out regularly, and would cost $6.10 a year under the same
conditions..... I LIKE the LEDs a lot....
I bought them at the Dollar Tree store for a dollar apiece....

There is no wasted heat from incandescent lamps during the colder months
which is over 6 months per year in some locations. Where does that make-up
heat come from?
The new LED lamps have one purpose.. to separate you from your money.
The new 100W screw-in LED replacements are supposed to be widely available
this year and are expected to cost about $40-50 each.
Incandescent 100W lamps are maybe 40-50 Cents each.. and they're being
banned in the US later this year.
It's for your own good.. don't worry.
Oohhhh.. but the LEDs they last like, almost forever.
Sure they will, manufactured with the cheapest components available, made as
cheaply as possible.. with Lead-Free solder.
Most likely manufactured in a country that has been opening new coal-burning
power plants at a rate of one new plant every week.
It's not a democratic country/society, and they're not even christians, fer
christs sake.
I have yet to get more than about 2 years from those 5-7 year CF lamps. The
CFs insure rampant pollution by spreading mercury and more electronic waste.
I haven't seen many LEDs that give off white light, some are bluish, others
kinda red.
LEDs appear to be extremely bright when you look directly into them, well,
the lens that makes up the body.. so they make great indicators for
appliances or electronic devices, but that's not the same as trying to
illuminate a room with LEDs.
Without the proper reflectors, even high-power 3W LEDs don't "throw" light
very effectively.
You can believe it.. LED lamps will be the salvation of the human race..
aren't we there yet?

Well, in a new super-market that was built in town last year they used
the "new" LED strip lighting in the freezer display cases and they
only come on when someone is in the aisle near by. This seemed like a
good idea since the usual fluorescent lamps do not work that well in
the cold and the heat they produce has to be pumped out of the
freezer. Within two weeks of opening, all the strips had to be
replaced due to "a manufacturing error" and I noticed a couple of days
ago that about 1/3 of the 100 or so strips have some sort of defect
such as all or large groups of LEDs not working. Like you say, it
looks like poor quality shabby quality product.
