Am I in the right place?

Andrew,

I'm not sure if this is where this belongs, but I'd like to ask you if you are aware of any studies comparing power compact PAR with metal hailde PAR.

Thanks for your help.

Hey Steve,
I'm not aware of any studies direactly comparing fluorescent to metal halide lighting. other than a very basic set of measurements I did a couple of years ago: Light Intensity (http://www.petsforum.com/personal/trevor-jones/light_intensity.html).

I will shortly be embarking on a series of measurements which will compare NO fluorescent on magnetic ballasts to NO on IceCap ballast to 150W MH lamps. The results are probably still a few months away (as I don't have a lot of time).

Once I have everything set up for this, I could add power compacts and a few other lighting types.

Basically, the set up will be a 48x18x18" tank with the various lighting types at "average" height above the tank and to measure irradiance levels at various places within the tank to build up a map of the light levels.
