If LED down lights are not an option, there are some good alternatives to consider.
Oyster lights is one of the most common ceiling light used and although bright it is rarely a very stylish light. This client from Summer Hill had a very tasteful idea by purchasing outdoor spotlights in black colour and getting them installed by us, replacing his old and outdated oyster lights. The result is astonishing, not only has he got a lot more light than before but the lights are low profile and make the apartment look quiet stylish.
The living room lights are a 3 track of 10 watt led and a 4 track, that’s 70W LED and quiet bright indeed. To control the brightness he had a LED dimmer installed
I can only recommend this solution to anyone who owns an apartment with concrete ceilings wanting Down lights
