Summarizing some of the salient points from recent discussions, I have
tried to outline some of the key decision points.

1. Do you have 110 volt AC available? If no, you have answers to
the wrong questions.

2. Do you care about power consumption? If no, see question 1.

3. Do you use dimmers or motion detectors? If so, do you have
neutral wire switches?

4. Are you concerned about tiny trace amounts of mercury? If yes
you've either been listening to some "off brand" news source, or you
are a true enviro weenie.

5. Are you concerned about getting the exactly correct color
temperature? If so, you'll need to shop a little harder.

6. Do you need absolute "instant on"? If so, are you measuring in
microseconds or milliseconds?

7. How many people will it take to change my CFL bulb? It depends
on which news group you ask the question in, how many people you need
to turn the ladder, and whether or not you live in California and need
to discuss the experience.
