I have just bought one to go in my shower light. It says do not use wit
an electronic transformer but to use a wire wound AC transformer or a D
transformer. I have connected it up to the existing transformer and al
seems OK except a very minor flicker in the first 2 minutes of bein
on. I have looked at wire wound transformers and they seem to be abou
the £40 mark which is a bit OTT for a single light fitting. Any idea
and any reason why the existing electronic transformer won't be an
good. Or how do I get hold of the correct transformer. Thanks i
advance

Most electronic transformers have a minimum load requirement. eg may say
10-75VA on it. This means minimum of 10 Watt lamp Maximum of 75W lamp (or
combination of lamps). Its to do with the internal voltage reglation
circuit. Look for a transformer that says (eg) 0-75VA

For a LED one you could use a much lower rated transformer than for halogen.
