Ampoule germicide 3 watts GTL3 culot E17

Needed a UVC bulb for my air purifier. They call for replacement once a year. Went to the manufacturers website (Bionaire True HEPA 360° UV Air Purifier) and found they didn't list one for sale. Figured I would just get one from Amazon. Wrong. I put in what I needed and like usual, Amazon gave me 1000 other bulbs that weren't even close. Google, same thing. I found this site; they listed what sounded like the correct bulb but no photo to verify. So, I emailed them a photo of the bulb with a ruler next to it for reference. They got back to me the next day and said that the bulb I was looking at was in fact the match to the bulb I needed. Ordered the bulb, free shipping, came in a few days. Exact match, great job! I hate when looking for something, it becomes a quest for the holy grail. This company has my business for anything in the future.
