Last month we bought what seemed like a whole truckload of the energy saving flourescent light bulbs. Before you start cringing, let me tell you that they've come a long way since they first came out.
They are not that harsh white light anymore. They come in a softer incandescent look too.
They don't only come in that unsightly 'coil' anymore. You can get them in normal lightbulb shapes, as well as globes. (The only thing I couldn't find were 150 watt equivalent globes and small chandelier flames)
We replaced most of the lightbulbs that we could find suitalbe replacements for.
Our electric bill was more than $50 cheaper this month!!!
(Full Disclosure Time: I found that the globes do take about 10-20 seconds to warm up before they are giving their full light. If you're running to the bathroom for a "quick trip", it might be a bit dim until you are already washing your hands.... ;) )
