Customers praised these bright LED panel lights at 6250 lumens for being "much more uniform than old fluorescent lights" and making a "big difference in garage settings." They appreciated adjustable color and power settings. However, reliability concerns emerged with 25% having faulty switches and dented corners on delivery.
These LEDVANCE Sylvania panel lights are brilliant at 6250 lumens, 50 Watts, and 4000 Kelvin CCT. I like being able to adjust the color and power. They make a big difference in a garage setting, where I installed them with the matching surface mount kit. The reliability is low; 2 out of 8 (25%) have faulty switches for the color and power. All 8 have at least one dented corner that is partially hidden by the mounting frame. The cardboard packaging was not damaged nearly as much as the steel bezels. I was able to get replacements for the 4 that I ordered, so I was able to complete my installation, but they should be handled more gently at the factory or designed with solid corners in the bezels.
