I can't seem to locate a LOW wattage night time bulb.. will not need over summer, but we've had some chilly nights recently and i'd rather buy a bulb rather than turn up the heat in my entire house! ;( Anyway, I read that the fluorescent "party" bulbs (i see at LOEW'S) are only painted red & will bother my white's at night?? this true? any links to a site where I can buy??
