Osram Vialox are regularly used to light roads and monuments as well as general outdoor lighting. The Osram Vialox lights are energy-efficient and last for a long time. They have an average lifespan between 9.000 and 48.000 burning hours, what ensures that maintenance and replacement costs happen less frequent. The Osram Vialox gas discharge light bulbs need a ballast to werk. At Budgetlight we offer these ballasts!
