which option is better ?

Definitely had a glass shade. What your looking for is a replacement with a neck so the lip sits on top of the screws. This site has a good selection but double check the diameter of the fitting: https://jmoncrieff.co.uk/John-Moncrieff-replacement-glass-light-shades/John-Moncrieff-clear-globe--with-neck-in-various--sizes- Ebay is a good source for replacement shades as well.

I bought a very similar version as in the screenshot. It was perfect for the kitchen. It was perfect for the kitchen. Cute, small, but enough size and power. It gives a nice light, not harsh, properly diffused. And I bought it really cheap. But for my loggia, that`s spacious enough. I decided to buy a lamp that doesn`t use electricity. I found one on amazon, as well as flag pole lights. I think it’s perfect cause the loggia is on the sunny side, so the lamp stores the energy and gives off a soft and pleasant lighting at night. I don't really prefer to sleep in total darkness and this kind of lighting helps me doze off. So, for those who have a balcony or loggia, I strongly advise buying these!

Dulux light and space paint are coloured already with special light reflecting articles. The paints are all light colours.
