In the era of smart farming and precision agriculture, automated lighting control has become a critical factor in optimizing crop growth. Often overlooked but most effective technology is the photocell light controller, a simple and energy-efficient device that turns supplementary lighting on and off according to surrounding light levels.
At Zhejiang Lead-Top Electrical, we specialize in photocell solutions that are already powering streetlights, signage, and industrial lighting across the globe. But did you know our photocells are also an ideal fit for greenhouse supplementary lighting?
Why Do Greenhouses Need Automatic Lighting Control?
In controlled-environment agriculture, such as greenhouses and grow tunnels there artificial light plays an important role in plant development. Mainly during:
- Cloudy days or long winters
- Low natural light environments
- Flowering and fruiting phase management
- Boosting crop yield and shortening growth cycles
Yet continuous lighting can be energy-intensive and harmful to plants, that’s why photocell-based automation adjusts lighting according to real-time lux levels, is increasingly adopted in smart agriculture.
In short, it saves energy, improves plant health, and enables smarter crop scheduling, automated lighting control forms a growing environment, stabilizing photoperiods that are important for crops such as cucumbers and cannabis, inconsistent lighting can trigger stress responses in plants, creating poor flowering or even crop failure, photocells eliminate guesswork by responding automatically to real-world conditions.
Another factor is labor savings. In regions where electricity prices fluctuate or human oversight is inconsistent, automated systems allow farms to maintain production quality without additional manual input.
Why Lead-Top Photocells Are a Game-Changer for Agri-lighting
Whether it’s a standalone LED grow light or a centralized horticultural lighting system, Lead-Top offers a full range of photocell solutions tailored for greenhouse environments:
Accurate Light Detection
- Equipped with IR-filtered phototransistors or CdS photocells for responsive and reliable sensing
- Customizable turn-on/off thresholds e.g., 10~16 Lux ON, 65 Lux OFF
This makes sure that lighting only activates when required, reducing wasted energy and avoiding photodamage.
Flexible Installation Types
- LT210 series (thermal wire-in): Cost-effective, moisture-resistant, ideal for fixed installations
- LT310 series (electronic wire-in): Fast response and extended switch cycles, perfect for LED lighting control
- LT124/LT134 (NEMA plug-in): Supports modular installations and remote maintenance
- LT600 series (Zhaga Book 18): Cloud-connected via DALI/0-10V also fits next-gen smart greenhouse platforms
Built to Withstand Harsh Environments
- IP66/IP67 waterproofing for conditions with high humidity
- UV-stable polycarbonate housing and heat-resistant PBT bases for long outdoor or humid exposure
Greenhouses experience constant condensation and high heat. Our photocells are engineered for those extremes.
Energy-Saving & Equipment-Protecting
- Zero-crossing switch options for safe switching with LED drivers
- Power consumption as low as ≤ 0.5W at 120VAC
By minimizing energy waste and reducing the risk of driver burnout, Lead-Top photocells support long-term sustainability and equipment ROI.
