amps vs watts cost?

So the HQI uses less watts and will be cheaper to run, but the m95 is more efficient?

Yes, the HQI would cost less to operate since it uses less watts. Butt, as a reefer, you want lamps with high watts because that typically means more light, right.

We need Sanjay to do an analysis on these two setups and figure out which one has the most PAR.

Confused yet? :lol:

The whole comparison came about as a discussion with Sanjay. xm bulbs are supposed to be run on an m59 ballast, but I have been running them on PFO HQI ballasts.

Well, you are very likely overdriving the XM 20K lamp with the HQI ballast. It will usually result in reduction in lamp life. With 20K lamps most people change in 8-10 months or less anyway, so the life may not be much of an issue.

Sometime overdriving the lamp will result in lower output from the lamp too. I have seen it in a few of the lamps I have tested, where the lamp actually perormed better on the M59 ballast than the "HQI".

So, I was comparing the two. Since the watt difference is minimal, I will prolly switch to the m59 as not to reduce the lamp life and avoid potential lower output.

All this stuff is soooo weird!

Well then, there you have it!
