I have a Diamond light for a smart table. It has 4 LED tube lights. I took the light to Menards to match it up. I have 2 questions. First, is there a special light that i need to buy? And second, how do you get the big light reflector out of the fixture? I dont wanna break it and I also dont want to take my light down. I was trying to get the bulb in by just taking out the end pieces but I cant do it by myself. Any help would greatly be appreciated!!
