So, I posted earlier about debating between HPS and a LED system. I did some research, looked at some spectrum analysis of it and decided to go with the Philips MasterColor 400W CMH.

One question I did have, I ordered a standard HPS 400 Watt magnetic 60hz ballast. From reading through forums this bulb will not work with the electronic/digital ballasts, correct?

Anyone have any personal experiences with these bulbs?
