Using highter wattage halogens ok?

[page3]

Ok, I know this is probably very obvious and I feel stupid for asking, however:

We have a couple of the following lights:

http://www.bhs.co.uk/mall/productpage.cfm/bhsstore...

Which comes with 6 x 10w halogen bulbs. Although it says G4 on their website, I believe them to be G9 (mains voltage) as there is no transformer in the fitting.

Is it safe to replace with 6 x 20w (or 6 x 25w)? I presume heat wouldn't be an issue as they are 'open' (ie: no bulb coverings) and the total draw would still only be 150w (in the case of 25w bulbs).

Yes, simply stuff, but thought it best to ask! BHS don't know!

EDITED TO ADD: Ok, serves me right posting from work. Seems G4 and G9 look very different, so I only need pop one out to see which it is. Still, cannot see how they can be G4's if no transformer is present.

There'll be a small transformer in the base. I've replaced built in transformers to make lights dimmable but I wouldn't exceed the lampholder rating as other factors like current and heat come into play when it's tested/type approved.
