Hi Igor, these lights are cast brass in chrome finish from, Gardens at Night, in Sydney.

the pavers seem have color variation,not very consistant,HaHa

The colour variation is due to it being a natural stone product and adds interest to the paving areas. For a more consistent colour we would use a different paver or tile that had less variation.

Nice to look at but difficult to live with. Reminds me of a party where someone took a serious fall. Might be careful about serving drinks there.
