For what it's worth: My package of Phillips DuraMax incandescent 40W bulbs claims 475 lumens. So this LED bulb we're discussing is about a 40 W equivalent.
Compare: CFL vs LED
Efficency: 9W vs 7W

Time to on: Several seconds vs Instant
Cost:
$2 vs $25
Life: 10k Hours vs 50k hours

Mercury: Little vs Less
Dimmable?: Some vs Yes
Cold OK? Barely vs Better
Me, personally, I'm a big fan of LEDs (not just in light bulbs, either) so I'll still spend $25 for the equivalent of $10 worth of CFLs.
