The Lighting Trade School Podcast
Why do landscape lights start blinking on and off? In Episode 41 of The Lighting Trade School Podcast, Captain Matt, Glo Show Shane, and Nate “The Illuminator” Mullen break down one of the most common and frustrating landscape lighting troubleshooting issues: blinking lights, overloads, low voltage, power driver problems, and what Nate calls hiccup mode. This episode starts with a real maintenance issue from one of Captain Matt’s clients. A section of lights in a blueberry patch had been working for years, then suddenly started blinking after being on for about an hour. Instead of guessing, swapping parts randomly, or blaming the lamps, Nate walks through how a professional lighting contractor should actually diagnose the problem. The guys explain what hiccup mode means, why a DC power driver may flash on and off to protect itself, and why that self-protection feature is actually a good thing. If a power driver senses a slight overload, heat issue, short, lamp change, bad connection, dirty incoming power, inrush current, or voltage problem, it may start flashing to warn you something is wrong before bigger damage happens. They also talk about the Critical Four every lighting installer should check before wasting hours in the field: * Incoming voltage at the outlet * Amperage on the primary side * Amperage on the secondary side * Voltage at the connections This episode is a field-level troubleshooting lesson for landscape lighting contractors who want to stop guessing and start diagnosing like pros. Captain Matt shares a painful lesson from a maintenance call where a simple voltmeter test would have saved him two hours. Shane talks about starting at the outlet, removing leads one by one, and eliminating problems methodically. Nate explains why amperage is the key to understanding system health, why temperature and electrical abuse can affect power drivers over time, and how inrush current can damage LED lamps and electronics. If you install landscape lighting, maintain outdoor lighting systems, troubleshoot low-voltage lighting, or train crews, this episode is required listening. Topics include: * Why landscape lights blink on and off * What hiccup mode means in a lighting system * Why DC power drivers protect themselves * How overloads, shorts, and bad connections create problems * Why amperage matters when troubleshooting landscape lighting * How to use an amp probe and voltmeter correctly * The Critical Four every lighting contractor should check * Why low incoming voltage can wreck your diagnosis * How a tripped GFI can waste hours if you do not test the outlet * How to isolate leads and troubleshoot one line at a time * Why temperature, dirty power, and inrush current affect LED systems * Why every lighting truck needs a voltmeter, amp probe, and extra power driver * How The Illuminati Lounge Club helps lighting contractors level up Most lighting troubleshooting problems get worse when guys start guessing.
