We have developed a new design of the LED TRIF RAIL article. Now, we offer luminous railings and handrails with round cross section. The first model was made to order for a stairs lighting design project. The resulting product is a graceful, elegantly shaped railing that is suitable for outdoor installation and convenient to use. With our apt design, this simple idea simultaneously fulfills several tasks: illuminating the stairsteps, indicating the location of the handrails, and contributing to the safety of the stair users.
