If you always wanted to go with IceCap lighting but didn't want to assemble it yourself, your wait has ended.  Aquarium Specialty has put together an all IceCap HQI Pendant application that accommodates 250 or 400-watt DE MH lamps.  This all aluminum pendant has the best reflector available at any price.  The pendant's wires end with a quick disconnect that plugs into the pre-wired ballast box that acts like a heat sink, has an on/off switch and an insulated cord with three prong plug.  Add a lamp to match the ballast wattage and you're good to go.
  
Priced for the 250-watt system.
