good: I got new LED spotlight bulbs for my entire room! MUCH COOLER! NO horrid heat given off by awful halogen spotlights!! Lower wattage and thus more energy efficient!!

bad: the bloody electrics in here are bollocks and don't friggin work at all except if you've got the shitty halogen lamps and EVEN THEN a lot of these sockets just... don't friggin work at all. less now that I've put the led bulbs in. *grump*
