I live in a rented property my landlord has just had a new kitchen fitted. The 6 downlighters are really dim.. I assumed this was because he would have used low wattage LED bulbs.. but as I started to take them out I realised the other bulbs got brighter the more bulbs I took out until there was just one bulb left it was really bright! How is this so? Does it mean they haven't been wired in right? Is it dangerous? A fire hazard?? As they are even 400lm (10watt) LED bulbs are really dim when all six are fitted!!
