Sorry to confuse, I won't be using the dimmer itself, I have it on the 100% output. I didn't know if the fact that it is a dimmer switch in itself would cause problems with the bulb or if it is only when you start to use the dimmer switch to a lower setting is the problem.
To clarify, I won't be altering the setting, just keeping it on the highest output. So on this basis, am I ok to use on my light?
Would both these options be ok...(the lamp's specifications show 220-240v / max 150w)?
I also have a question about my bathroom halogen lamps but will post that as a separate question to you.
Many thanks in advance, your information is very helpful and not something I was aware of!
