Energy Star has a fun, interactive site on bulbs. http://www.drmediaserver.com/CFLGuide/index.html
While the site focuses on home uses, many outdoor sites have small lamps beside guest beds, gathering areas with ambient lights, outside lighting, etc.
You can:
- Choose a bulb, based on the fixture
- Learn where each bulb works best
- Find the right light (color temperatures)
- Learn tips (Saving money, where CFLs shouldn’t be used, recycling, etc.)
