Rated 4.1 out of 5 by 58 reviewers.
Rated 5.0 out of 5.0 by Exactly What I Needed My light fixture is over 20 years old and I was sure I would have to replace it when the diffuser cracked during a lamp change. Did some research and found that Home Depot carried a replacement. Figured it was to good to be true but ordered it anyway and it was perfect. Fast shipping. Good packaging. It's nice to know that Lithonia Lighting doesn't have to reinvent the wheel every two years like most companies. August 11, 2015
Rated 5.0 out of 5.0 by New Flexible Diffuser Solves Cracked Diffuser Issues When your diffuser cracks while changing bulbs, it's time to replace it. The new diffuser is flexible and will not crack when you insert it. My first diffuser only lasted about 6 years before it became brittle. Shipping is fast and it comes well padded in a carton box.

Rated 4.0 out of 5.0 by Broken on arrival When I opened the package the corner of the diffuser was broken but I installed it anyway. September 9, 2015
Rated 5.0 out of 5.0 by Good quality, excellent packaging The 5 defusers arrived in great shape. Packed perfectly, The gentleman that helped me seemed very knowledgeable and walked me right through the process. The price was good, but when I figured in the free shipping, it was a very good deal.

Rated 4.0 out of 5.0 by Light diffuser I ordered a new diffuser to replace one that broke when we took it out to replace the bulbs. I didn't have a model number on the old fixture. I ordered the diffuser online after looking at the various models in the store, choosing the one that looked most like what I needed- very easy to do. It turned out that the old fixture was about 1/4 inch smaller than the new ones so the diffuser didn't fit very well but we made it work. The corner also got broken off in the process. I thought $48 for the new diffuser was high but I needed a new one. I might expect the new diffuser to be a bit less brittle. I am glad they send installation instructions, as they helped make it work. February 10, 2015
Rated 5.0 out of 5.0 by Perfect replacement. We needed a replacement diffuser for our kitchen light fixture, which we originally purchased from Home Depot. I was so pleased to find the exact replacement that we needed at a reasonable price. Lithonia Lighting shipped the replacement quickly and it was carefully packaged so that it arrived in perfect condition. We were also impressed that all the packaging materials were recyclable. Great service Home Depot and Lithonia Lighting! July 24, 2012
Rated 1.0 out of 5.0 by Arrived Damaged Order the diffuser because mine was cracked. When the new diffuser came in, it was in worse shape. I took it back to Home Depot and hopefully this one isnt damaged. These diffusers are too fragile! September 23, 2014
Rated 1.0 out of 5.0 by Brittle, easily cracked, junk. Instructions are terrible. Installing this brittle diffuser is very difficult without cracking it. Sure, you might do it the first time, but after your next light bulb change, good luck! It's an overpriced piece of junk! Very dissapointed. April 1, 2015
