Metal Halide PAR value

[Razor]

I just found this:

Really neat way to compare the color of two bulbs on what happens to be my ballast (PFO Standard).

The XM 10K should be fine on the standard ballast - that's what it's intended for.

As mentioned earlier, you might also check Sanjay's data. Go to his site and select your ballast - you'll get results of all lamps he's tested it with:

Good info on PAR and color temps.

The problem with that comparision is it uses the PFO ballast as its sole ballast. That's great if you use the PFO ballast, but the color and PAR can differ dramatically if you use another ballast.

Here's the articles Sanjay has written on lighting, including some really nice ones regarding reflectors (which is too often overlooked .... it's just as important as any part of the lighting system):

I agree, but lucky for me I'm using the PFO Ballast. Just thought it was a neat way to really be able to see what different bulbs can do to the look fo your tank.
