Rated 3.8 out of 5 by 4 reviewers.
Rated 1 out of 5 by Product Failed This BR40 was great while it lasted. Product started failing after 3 yrs and ~1,000 hrs use. 1000 Bulbs handled it well however. They gave me credit for two failed Lighting Science units and recommended a replacement (TCP LED12BR40D30K) which I have installed next to the remaining Lighting Science units. The TCP is nearly a same replacement. The low dimming profile is a bit different, the 3000K matches well. Now the bad thing is I have 10 more of these Lighting Science waiting on failure. I am confident 1000 Bulbs will continue to back up the product. June 26, 2015
Rated 4 out of 5 by 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. November 29, 2012
Rated 5 out of 5 by Wonderful Bulb I installed in a house with high ceilings and the owner thinks I am the worlds best!!!! Ordered 12 for her - order now for 70 - Love you guys May 10, 2012
Rated 5 out of 5 by 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. April 13, 2012
