Today’s step was putting in low energy light bulbs. These quad bulbs are 20w, which should be a good saving in joules. They are also guaranteed to last 10,000 hours, which would be a big improvement on our current ones. But the light output is disappointing. They claim to be equivalent to 100w regular bulbs, but they are much dimmer – closer to a 60w. Not sure I’m going to respond well to the dimmer rooms, being an SAD person.
