Pendant Light fix?!

Hi, new to the forum thanks to this reason. About 2 years ago purchased Tom Dixon pendant lights from a seller in Hong Kong, needless to say 2 of the lights stopped working thanks to the cheap plastic that held the bulb. Other than that, they look great. I reached out to a lamp repair place and they want $100 per light to fix (all 3 cost me $100), so before I trash them, I want to see if I can fix'em as I need the light!
