The JL-245CG smart light sensor photocell switch by Long-Join is designed to meet these needs. Together, these features make JL-245CG a reliable tool for the next generation of smart city lighting. How Does the MQTT Protocol […]
The Future of Airport Lighting: How Smart Photocell Systems Are Revolutionizing Energy Efficiency at Global Transportation Hubs
Outline Airports never rest. Lights must stay on around the clock. However, it can toll heavily on both energy and money. Traditional lighting lacks flexibility and wastes power. Photocell switches change that. They adjust lighting automatically to match real needs, offering a viable solution against costs and emissions. With IoT integration, airports gain more than […]
LTE Cat.1 for Smart Lighting: The Goldilocks Solution in IoT Connectivity
Outline Smart cities need reliable communication for outdoor lighting. But with so many IoT options, which one truly fits? 5G is powerful but costly. NB-IoT is cheap but too limited. LoRa works well locally but lacks global reach. LTE Cat.1 sits right in the middle. It offers stable coverage, moderate speeds, and cost efficiency. For […]
IR-Filtered vs CdS Sensors: How to Choose the Right Photocell for Your Outdoor Street Lighting – JL-401E(R) vs JL-401C Explained
Outline Choosing the right photosensor switch for street lighting can be tricky. The wrong choice can cause false triggers, wasted energy, and higher maintenance costs. The JL-401 series offers two popular models: Each uses a different sensor technology, and each serves a different purpose. This guide breaks down their differences so you can select the perfect […]
How Photocells Work with Contactors to Power Smarter Outdoor Lighting
Outline Outdoor lighting needs to be efficient and reliable. But how do you control large lighting systems without constant manual work? The answer is often simpler than people think — a photosensor paired with a contactor. This setup: So, regardless of your lighting needs, understanding how these two devices work together can make your system more […]
Photocell vs. Motion Sensor: Which Is the Better Choice for Outdoor Lighting in 2025?
Outline Photocells and motion sensors are currently the most employed means for smart lighting. Both help save energy. However, they work in different ways. Photocontrollers respond to natural light, and the motion sensors react to movement. Choosing the right one needs careful consideration of where and how you use them. This guide breaks down each. […]
Best Photocell Options for Coastal, Snow, and Desert Climates
Outline Not all outdoor light sensors are made for every climate. Some even fail just months after installation. Salt air, freezing snow, or desert heat might be the culprit. Each environment creates unique challenges for outdoor electronics. That’s why choosing the right photocell for your region is critical. In this article, we’ll explore the best models […]
High-Mast, High-Stakes: Why Long-Life Photocontrols Are Critical for Large-Scale Outdoor Lighting
Outline How do lights keep on shining night after night? Is it just about the bulbs? It’s not— it’s the photo controls behind them. In massive outdoor installations, even one failure can trigger costly maintenance, safety issues, or dark zones. These are not your average streetlights. They’re critical systems, often placed where access is tough […]
Empowering Smart Streetlights: How Long-Join Integrates UART, Zhaga, and Solar-Grid Hybrid Controls into One Intelligent System
Outline Why settle for basic lighting when cities need intelligence? Streetlights today must do more than turn on and off. They need remote control, sensor compatibility, and reliable power—even when the sun disappears. But finding one system that handles it all? That’s rare. At Long-Join, we’ve created a smart solution that combines UART control, Zhaga […]
Why Salt Spray Resistance Matters: How Long-Join Photocontrols Withstand Coastal and Harsh Environments
Outline Outdoor lighting doesn’t just need to work — it needs to survive. In coastal cities, humid climates, or polluted industrial zones, corrosion is the enemy. Salt in the air can eat away at enclosures, terminals, and connectors. Over time, that means flickering lights, failed lighting controls, and costly maintenance. That’s why salt spray resistance […]
