Osram Haloline light sources have a double ended R7s base. These small but bright light sources are dimmable, can be connected to 220 - 240 V and have an excellent color rendering. The built-in UV filter prevents discoloring of objects by the emitted light. Use the filters on the right to select the right wattage and color. Use your current light source as a guideline to choose the perfect light source for your application.
