Downlights are excellent for kitchen, bathrooms and hallways, IMO. They look good, modern and more importantly provide required illumination.
I won't use it for my living room or bedrooms but have seen people do and it's up to them, may be one day I will.
I find Aurora the best brand, ease of use, product variety, support and warranty length 5 years plus they are UK based. Their website have videos for each product and downloads too. I have used the EFDpro range in my kitchen, did it myself, very easy to install and recommend it.
