We currently have VHO lighting on there. We had a setup over one of the planted tanks that we had bought at an auction for about $20. We got some SW bulbs, and that's our current setup. The LPS and softies seem to be doing really well with the lighting.
We will be getting a Solaris system in a few months. Our electricity bills are insane. Last month was more than $800, so metal halides aren't an option. Sure, it's 110F every day here in the summer, but still... So, we're going for Solaris, and hoping the electricity costs will pay for the unit over 5 years.
