The URail rail luminaire -Circular- is equipped with an energy-saving lamp (tube) and is compatible with all URail items. In combination with the corresponding URail components, you can create your own individual lighting system with a total output of up to 1,000В watt. If you plan to regulate this system with a dimmer, we recommend selecting a URail product with halogen technology. Currently, only a small assortment of specially designed energy-saving lamps can be dimmed.
