As a product this is fine but as a lighting system- from a householders viewpoint is unnecessarily complicated.
Would rather have a system where just LED bulb can be changed. Changing these is a wiring job!
They are expensive relative to bulbs and although guaranteed for 3 years 3 out of 4 of mine have failed within 2 years. Manufacturers suggest could be because they are on same circuit as the extractor. ( not recommended). As mine are in a bathroom it is usually normal practice..
Beware when having new LED lights fitted that they are not this type..
