Rated 4 out of 5 by DaleM Excellent Bulbs (4.5 stars)
Bright bulbs with excellent color consistency. Aside from a high (relative price), the only minor quibble is that they're not quite "instant" on, having ~ 1 sec delay from switch flip to light response. Still, when they're on, they're on (unlike CFLs which need the warmup) and the consistency is excellent. Going to be adding dimmer switches soon. Highly recommended.

Rated 5 out of 5 by CJC1 Looks great
$45 for a light bulb is a little crazy, but after my "long life" CFL failed after 200 hours and all the CFLs seemed to be getting bad reviews, thought I would give an LED a try. Not a huge number of options for R40 dimmable LEDs...but this looks great. The 3000k light is warm and inviting, and it's instantly at full power #unlike the CFL it replaced#. If LEDs come down in price, I think CFLs will have a short lifespan.
