Halogen light bulbs « Trying to be Green When we got a new kitchen last year our builder put in halogen lights - 12 of them, each at 50W. Making a grand total of 600W of power every time we turn on the lights. Which is a lot of the time at this time of year. They are often on from 5pm until 11pm. From using our electricity monitor we can see that this is the biggest drain on our electricity use. in Public bookmarkswith commentfrancoisgreenhalogen
