Do yourself a favor and learn to distinguish bulbs by their lumen output,
not their incandescent wattage equivalence. That's a practice that should
never have been implemented. It's not really a direct equivalence, and it
just ends up making folks say the wrong thing (e.g. saying 40w when they
really have a 7w).

Also, make sure the Crees are rated for enclosed installation before
putting them in your outdoor fixtures. Most brands are not. I use the ULTRA
bulbs by Sylvania and the off-brand EcoSmart bulbs. Neither, of those that
I have bought, have been rated thus.

My favorite LED bulbs so far are the Phillips (damn expensive, but coming
down; still worth it, though) and the ULTRAs. Just about every bulb in my
house is a LED. My power bill, with a SEER 10 A/C unit running, for May was
$99 after taxes and fees. They make a huge difference.
