My bathroom light kept blowing I changed it to a pendant, it was a circular type bathroom light with the glass over top (Bayonet bulb). When changed to a pendant fitting the bulb kept blowing so I got a spark to fit me a brand new bathroom light fitting with G9 bulbs. Light is still blowing. My extractor fan in my bathroom is not working, could the steam be making the bulbs blow. I know it is possible but on 3 fitting ?
