The APOAEYB - Replacement Bulb for Bell & Howell/Eiki/Apollo/Da-lite/Dukane Products, 82V is not a replacement for a #50 bulb.
Thank you very much for your question. We did some research and called GE. They said that this was a Fluorescent lamp and that it is infact a FCL T5 Type 22 bulb. Their representative did not have information that it was made for a make up mirror, so we went to their website which just had techical information. We think this item will work for your application, and if you are not happy with your purchase we will be happy to provide with a full refund. Feel free to go to gelight.com.
