Customers find these LED tubes better than fluorescent lights, providing 1/3 more light and being easy to install, with one customer noting they help reduce shadowing effects throughout the space. Moreover, they work without issues and save money on electric bills. However, durability is a concern as some customers report bulbs breaking at one end. Additionally, flickering is a mixed aspect, with some customers reporting no issues while others experience significant problems.
