We are offering 150w Halogen Tube Reolite. the filament is made with a tungsten filament instead of wound metal, and is contained within a small amount of inert gas such as iodine or bromine. The combination of the gas and the tungsten filament increases the lifetime, efficiency and color temperature of the bulb in comparison to an incandescent lamp. The advantage of halogen lighting is that they can be smaller in size and produces a brighter and controlled color temperature to illuminated objects giving a sharp and bold appearance.
