The HD Telescopic Riser from Auroralight is designed specifically for fixtures larger and heavier than our previous 12v offering such as the: LED LSL4 and 120v: SL20, SL30 and MSL 16, 20 and 30 Ceramic Metal Halide spot lights. The HD risers significantly reduce system maintenance by allowing the fixture to adjust upward as the landscape matures around it. It is a quick solution for an existing problem or a proactive application allowing for future growth in the landscape. Machined Brass and Copper construction with Silicone O-rings and heavy duty clutch assembly. Custom sizes available, please consult factory. Each unit is shipped complete with a ground stake assembly and cord set. See below for available mount options.
