As illustrated by my lamp conversion project, the
current limitation isn’t LED efficiency or lifetime, but the
initial investment. LEDs are not yet universally cost-effective replacements for incandescents and compact
fluorescents. However, in certain niche areas, the added
cost is acceptable. A highly publicized conversion involves
replacing the 160, 100W mercury vapor lamps on the
Brooklyn Bridge in NY with 24W LEDs. The LEDs are
supposed to last three times longer than the lamps and
save 24 tons of greenhouse gases per year.
What niche areas of alternative lighting can you
identify and exploit — for your purposes and the good
of the planet? If you devise something, please consider
sharing it with your fellow readers. NV
