Municipal street lighting projects in South America demand reliability. Voltage instability is common. Climate conditions are harsh. Tender specifications are becoming stricter each year.
Selecting the right photoelectric controller is no longer a simple price decision. It directly affects energy savings. It determines maintenance costs. It influences long-term system stability.
Long Join’s JL-205F and JL-207F are two widely used models in public lighting projects. Both meet core operational needs. Yet their technical positioning is different. This article provides a clear comparison.
Why Is It Important to Compare JL-205F and JL-207F Photocell Sensors for South American Municipal Tenders?
Municipal lighting projects in South America face unstable power conditions. Many grids in the region rely heavily on hydropower. This makes them sensitive to drought and fluctuating output.
These issues contribute to voltage variations and outages that can stress lighting equipment.
In this environment, resilience is not just about technical specs — they are procurement priorities. Strong surge protection and wide voltage tolerance help prevent light photocell failure during spikes and grid irregularities.
Choosing the right photocell sensor directly affects energy efficiency and long-term operational stability. A suitable controller lowers maintenance costs and improves tender competitiveness.
Comparing JL-205F and JL-207F lets municipalities match product capabilities with real on-ground challenges and tender requirements in South America.
What Are the Core Technical Features of JL-205F Photocell Switches?
JL-205F is a robust photocell lighting sensor designed for standard outdoor lighting control. Here are its key features:
- Its rated voltage range is 277-480 VAC. This supports 50/60 Hz grids common in municipal installations.
- Rated load capacity includes up to 1000 W tungsten and 1800 VA ballast. This makesit suitable for traditional street lamps.
- Its power consumption remains low at about 1 W. This helps reduce idle energy use in large deployments.
- Light sensing trigger range is 16-30 Lx turn-on and 30-60 Lx turn-off. This offers flexible automation.
- Higher IP protection ensures dust and water resistance in harsh weather.
- Surge protection is 510 J/10,000 A. This guards against transient spikes.
- No zero-cross technology keeps operation simple and cost-effective.
Typical Application Scenarios
JL-205F outdoor photocell light sensor fits projects with standard load requirements and basic lighting control needs. It excels in straightforward street lighting, residential roads, and urban pathways where simplicity and rugged protection matter most.
What Makes JL-207F Technically Advanced?
JL-207F light sensor photocell switch stands out due to its very wide voltage adaptability. It supports 105–528 VAC, making it ideal for unstable grids and varying supply conditions often seen in large municipal networks. This wide range reduces failure risks from voltage swings and increases compatibility with diverse power systems.
Other key specs include:
- Higher load capacity of up to 1800 W tungsten and 1800 VA ballast. This offers flexibility for heavier street lamps without derating.
- Its low power consumption of 0.5 W helps save energy across hundreds of units in a project.
- Consistent trigger levels of 16 Lx on and 24 Lx off ensure stable automation without ambiguity in light sensing. This supports dependable night-time automation.
- Flexible surge protection ranges from 110 J–640 J and 3500 A–40,000 A. This guards equipment from severe transient events.
JL-207F also integrates zero-cross technology, preset lux values, and time delay to reduce false switching and extend relay life. These make it suitable for high-load municipal roads, expressways, and large-area street lighting projects where reliability and control precision matter most.
