[stephane]

HQI is simply another aquarium legend noting more

HQI is a osram trade mark for there Powerstar metal halide bulb line from 70 to 3000 watt mogul base and double ended all included. For exemple calling a hushio double ended bulb a HQI is like calling a Yamaha snowmobil a skidoo

here is a link to the only real HQI bulb in this world http://www.osram.com/pdf/service_corner/hqi_e.pdf

a bit of story http://www.sylvania.com/press/09142000.html

here is the catalog of all HQI bulb http://www.osram.no/brosjyrer/english/K01KAP5_en.pdf

Andy is not realy rong calling his ballast (Sodium son agro 430) a HQI ballast because it is the right ballast to run the REAL HQI bulb

But if you go in europe HQI is the way to call ALL metal halide
no mater it is a mogul or a double ended so any metal halide is a HQI anyway
