Ok, so the sales tactics and prices on this website seemed a little fishy...so I called and left messages 3 times and got no reply. Obviously, I did not do business with them. I have not been able to find any shop that sells the Phillips bulb along with a complete lighting system. I ordered a 150watt Phillips bulb from 1000bulbs to replace a hps bulb in a mini-sunburst system; the sales department assured me that it was compatible, but it was not, and I ended up paying $18 shipping to return a $25 item. Does anyone know where to get the Phillips CMH as part of a system, or where to get the bulbs from a reliable source? I have been getting my GEs from HTG for $189 shipping included, and they are excellent(the lamps AND the sales team), however I really want to try this side-by-side comparison.
