Three have gone in one room leaving me in the dark, one in the hallway two spotlights there) and one in the bathroom (two there also).
Changed the one in the bathroom, both now working fine.
Hallway, no play. One apparently dead light (brand new).
Bedroom, nada. None of the three brand new lights are working at all.
None of these went out in a circuit-blowing pow. They all went individually over time until I realised I was in virtual-dark and tried to replace them (when the first one in the bedroom went I tried to replace immediately and it did nothing, so I was left with two and then one until eventually no light).
What the hell is going on?
