I converted most of my bulbs in my house to Philips LED lamps from Home Depot. I had a few teething problems, with some of the bulbs initially. Some of their earlier floodlights were around a single bright LED, and it was annoying to have in an angled fixture. I took it back to the store, and found newer ones that were built around a multiple LEDs and had a diffuser.
Some bulbs are still incandescents, mostly because I haven't been able to find a satisfactory replacement. These are small chandelier lights (that would need at least 40 watt equivalent output) and the three-way bulbs on the night stand (Cree just released them). Products are available, but both require shipping from the States. I'll wait a little longer before making the complete switch.
