3.) Less energy consumption
4.) Less heat (even after 10 hours on I can put my hand on the unit vs. MH of which I still have a nasty scar on my arm from a fraction of a second contact with a fixture)
5.) Less bulb replcement cost (up to debate)
6.) Even light in all corners of the tank, no shadows or MH "spolight" effect
Just a few points that sold me.

Hmm.
1.) My CL MH unit is slim and lightweight
2.)I've always been able to select a color temp that was to my liking (really, how many combinations do you need)
3.)Have no info on this, but I'm sure any savings are negligible over the TCO (total cost of ownership of tank)
4.) With my enclosed HQI setup, heat is not an issue, I can touch any part of my fixture.
5.) <$200 yr, I'm happy with value for dollar here
6.) depending on fixture, reflector, same thing with MH. although I prefer different areas of exposure for different species placement in tank. I certainly don't have any "spotlight" effect in my tank.
