The square is one of the most popular shapes anywhere in and around the home. This is why it's only logical for STEINEL to believe in this familiar design that people like. And combine it with innovative LED and sensor technology. Just like all of STEINEL's LED sensor-switched outdoor lights, the L 690 LED comes with the full range of functions too: basic light level function, soft light start as well as adjustable time and twilight threshold. Due to the high demand, we took a good look at the L 690 and the 691 LED and equipped this system with even better illumination characteristics and even better efficiency. The lamps can also be connected to the network via cable. This makes this robust and solid outdoor light a pleasure to work with in the professional environment.
