Rated 4.1 out of 5 by 14 reviewers.
Rated 5 out of 5 by Good selection They had a selection of different color temperatures of these bulbs in stock. The clerk was helpful in me finding the correct one for my use. September 23, 2014
Rated 5 out of 5 by Great for under cabinet kitchen lighting I use these in various lengths in my kitchen for under the cabinet countertop lighting. They give off lots of bright light to fully illumine our counters. The shade is "cool" so it is a bright, bluish type, not the yellowish, warm type. This shade is better suited for kitchens and baths. We use these constantly when in the kitchen along with pendant lighting, rarely ever needing to turn on the overhead ceiling lights.

Rated 4 out of 5 by Lights Bulbs that cost a lot and work okay My only problem with this product is that they do not last as long as I feel they should August 26, 2014
Rated 5 out of 5 by Nice Bright White If you are looking for a bright white light instead of the lower yellow looking glow this is the one for you. I think a lot of us like it because the yellows are always plentiful in the store but the bright white is always low or nil stock. Get you SKU# and call the store before you go. January 14, 2014
Rated 4 out of 5 by Good purchase - average life of 2 1/2 years Although we've recently switched to soft white instead of cool white, bulbs we've purchased here have an average life of 2 1/2 years. Our use is over the kitchen sink and in the mud room. useage of 3-5 hours per day December 7, 2013
