I'm not looking to stir up any arguments. Please help me understand. Your website says that one of the AOLP's goals and objectives is: "To provide a Standard for Installation of Low Voltage Architectural & Landscape Lighting Systems that meets all of the requirements of the National Electrical Code and the Underwriters Laboratories (UL) "Standard for Low Voltage Landscape Lighting Systems". Unique Lighting Systems is a major AOLP sponsor and as far as I know still takes a stand contrary to UL 1838. At least one other manufacturer/ sponsor also offers (last I checked) some equipment that doesn't comply with the UL 1838 standard. So my questions are: 1. How do you reconcile the two positions? 2. Which standard is reflected in the current CLVLT study guide and test?
