Here is one other question I had about them. The fixture I bought for
the front porch uses 4 of those small socket type bulbs and it says max
25W. I am going on the assumption that is 25W incandescent. I bought a
box of 60W equivalent which are actually 5W I believe. Since they are
actually only 5W is it OK to use in this fixture?

LEDs are now as cheap to make as CFLs, expect the latter to basically die out.
I am unaware of _any_ advantage they offer over the alternatives. Good
riddance.
(LED bulbs are also fluorescents, so phosphor color arguments are null. The
phosphors
are just excited by blue or UV LEDs instead of UV from mercury vapor arcs. LED
bulbs will also exhibit age-based dimming as the phosphors, and/or LEDs, age
and die.)
High-wattage LED replacements are still spotty, but they seem to be at the 60W
level just fine. Light quality is excellent, as is cold environment range. If
you should
get the all-glass exposed-filament types, up to 40W I believe, I think they can
even
get wet. To the eye, they are nearly indistinguishable from incandescent lamps
of
the same class. I love, love, love the 4W bulbs we're using in the outdoor
sconces,
they're 40W equivalents.
The closer they look to incandescents the better I like them. The worst are the
very plastic-ey ones with finned heat sinks, etc. In lower wattages they don't
need
heat sinks, because they're using helium-filled envelopes. He (and H) have
nearly
10x the heat-carrying capacity of air, or Ar, N, CO2, etc., so they can use the
entire
glass envelope as a heat sink.
LEDs are superior (to incandescent) in drop lamps, but inferior in ovens---Easy
Bake
or otherwise. LEDs can't take the heat, nor do they generate much. So don't
use them
in your brooder houses...
