Thank you for your recent inquiry with The Home Depot. I contacted Home Depot store #0680, they stated they have 17 currently in stock. Unfortunately, these will have to be purchased at the store or purchased online and shipped to home. For any other questions, please call us at HomeDepot.com Customer Service 800-430-3376. Thank you for shopping Home Depot.

Rated 5.0 out of 5.0 by Happy with lights Exactly what I needed. The gentleman that helped was great in helping me pick out the correct replacement lights for my basement. April 7, 2015
Rated 5.0 out of 5.0 by Made a big difference At the time, I was only going to replace the one burned out bulb. However, the price for the set of 10 was too good to pass up. I decided to replace all the bulbs in the garage. This made a huge improvement. So much so, I replaced the bulbs in the laundry and utility room. September 16, 2014
Rated 5.0 out of 5.0 by it's lights best priced bulb in store's selection. Now when I turn on my switch the lights come on! Highkly recommend to those who need lights. September 16, 2014
Rated 4.0 out of 5.0 by light bulbs Not sure why Home Depot would send me an email rating light bulbs, but okay......... These bulbs make light when there was dark, provided you send 110V to them. August 19, 2014
Rated 4.0 out of 5.0 by Casts good overall light quality for replacement bulbs in garage, basement, & laundry areas. Still testing first set of bulbs in replacement locations for surviving duration; but overall quality of light cast from these bulbs equals or exceeds most comparable lights for intended garage, basement, and laundry areas at this time.
