Hi. I need to buy 16 replacement downlights for my kitchen, which is being decorated next week. The current lights have replaceable bulbs but so far (in Screwfix and B&Q) I can only find downlights with integrated bulbs. I don't want to have to call an electrician every time a bulb goes, and risk damaging the ceiling, as well as risk having to replace all 16 if I can't match the one needing to be replaced.
Why are they all integrated? Is it still possible to buy non-integrated downlights and, if so, which brand would you recommend?
