I'm having trouble finding a curved version of a downlight with this fitting that I bought from a large store. I could only find 4 types of straight tube bulbs in branded bulbs and they are too long for my fixtures. I've used them but they don't look very good because the ends of the tubes fit snugly into the diffuser in the mount. These lamps arrived well packaged and work perfectly. I didn't notice any flickering, color issues, or other oddities due to the non-brand name. Totally worth the price (for me) and looks a lot better in my fixtures than the more common 4 tube bulbs with this base.
