Osram HQI-E lamps are bright light sources that can stand temperatures up to 13000º. These light sources have a lower CRI, which means that the color rendering is not very good. These lamps are designed to be used outdoors, like in parking garages or factories. Here, color rendering is not always of priority. Before ordering your Osram HQI-E lamp, always check the base and light output to make sure your light effect remains the same after installation of you new light source.
