Osram HQI Others
Next to the Osram HQI-T, HQI-TS and HQI-E gas discharge lamps, there are other lesser used kinds. On this page you will find less known options like the HQI BT, but also the Osram HQI-R with a 2-pin base. These light bulbs are available in different colour temperatures from which some of them are dimmable. The Powerstar line by Osram offers HID bulbs with good optical properties and a high luminous flux.
