Portable steamer replacement bulb


hi I have a table top portable facial steamer it has the code F100 on the front of it and I am trying to find a replacement ozone bulb as it has gone out on it. I have contacted various beauty suppliers all of which can not help me as they don't stock bulbs even though they stick the same kind of steamers. Has anyone else found someone that stocks them or have you had the same thing happen and no longer use the light facility?
