Hi all,

Thanks for the clarifications with my question about energy saving
bulbs and wattage.

And while we are still on the subject, I would like to ask one more
related question...

I once bought a fixture made in Poland (I live in the US). The seller
told me I can use 60W bulbs. The fixture turned out to be marked for
use with 75W bulbs, and there was a sticker on each socket telling me
to use 40W bulbs.

I use 40W bulbs to be on the safe side, but...

What is the issue here? 220V versus 110V? Or something else?

Thanks,
Arkadiy

The issue is heat. More watts mean the fixture will get hotter.
At some point, the fixture will be damaged -- plastic parts
including insulation can melt. In the extreme, they start to
burn and you have a fire.
