With respect to Jeromy Shepherd's question about power compacts, $656 is a lot, and may or may not be "fair." If you are talking US dollars, and you have that sort of money to spend, I'd go with 2 or 3 250 watt metal halides. The pendants are versatile and easy to install/hang. I'm very happy with mine. T-8s are an equally good choice. -- Dave Whittaker ac554 at FreeNet_Carleton.ca
