Replacing halogen bulb with LED

WDHatton

Hello, I'm seeking a little advice, please!

I have purchased a tablelamp which came without bulbs but takes G9 halogens rated up to 40W. I want to replace these with lower powered LED G9 bulbs for efficiency reasons, however having just bought the bulbs my wife pointed me towards a card attached to the lamp saying:
"This luminaire is compatible with bulbs of the energy classes: C, D" and has the more efficient ratings crossed through.
Does anyone know why it wouldn't be compatible with more efficient bulbs and what risk there is in using a more efficient bulb?

Thanks
Will

Is the tablelamp fitted with a dimmer switch?

It says something about the fitting here.

Hi, thanks for your reply! No, just a standard on/off switch.

Frankly I can't see any problem, a more efficient fixture creates less heat, and less heat is always a good thing in modern electronics. However, are GU9 fitting bulbs 240v or 12v? If 12v, the LED may not provide sufficient load for the transformer to recognise that there is a load, in which case, darkness.
