the wiring can easaly be changed if the australia is different from findland.

Certainly a unique light!

Though I don't know for certain, I think the cotton/linen shades are removable. I wasn't able to determine this by my searches. This could easily be confirmed by making an enquiry to supplier before purchase. Alternatively, a handmade one could be made removable by making shade slightly larger than frame and making ties.

So, what color did you eventually choose? I am really interested because the house we have just bought has similar color ceilings. I was also wondering about the color of the light fittings. I think that I will get some color changing LED light bulbs and have them installed all around the house. I like them more because you can both use them as a regular bulb or change the color to any you would like. It is also possible to control them using an app on my phone, making it so easy to control them. Now I think that it would be the most reasonable decision if I installed white bulb fittings so they look good with all the colors the bulb can make.
