I have a ceiling light fitting installed in a shower room during 1999. It's about one foot from the shower cubicle and the ceiling is about 7ft high, so it should be an IP44 rated fitting. I took it down for cleaning and there's no IP rating marked on it. My wife bought it originally and thinks they said it was 'suitable for bathroom use'. I don't know when the IP ratings were introduced (post '99?) but is there any other way of establishing if it is safe?
