Osram Hallogen Rod, 64705, 230V, 300W

Halogen Osram Haloline Star 64705 300W 230V R7s linear halogen eco lamps use a special infra red reflective coating on the inside of the envelope and a low conductivity xenon gas filler to help reduce heat loss from the filament. These two technologies help to reduce the energy required to maintain filament operating temperature.
