Can a single technology redefine how our cities light up at night?

The rise of NB-IoT is doing just that — connecting every streetlamp into a smart, data-driven network. When Signify acquired Telensa’s smart street lighting business, it sent a clear message: the future of illumination lies in connectivity.

This move didn’t just strengthen Signify’s global influence — it reshaped the direction of the entire industry. As global leaders adapt to this shift, Long-Join is already stepping forward, equipped with mature NB-IoT photocell switch solutions and a 20-year legacy in outdoor lighting control.

What Does Signify’s Acquisition of Telensa Reveal About the Future of Smart Street Lighting?

On July 2, 2025, Signify acquired Telensa. This signals a major move into single-lamp intelligence. The deal brings Telensa’s NB-IoT and ultra-narrowband controllers into Signify’s portfolio.

Key points

• Telensa has deployed more than 2 million light-points in over 400 cities globally.
• The acquisition gives Signify access to narrow-band and TALQ-compliant platforms, previously unlicensed radio space technologies.
• It positions Signify to deepen its role in the UK and North American municipal markets, where networked street-lighting is an investment priority.
• The shift toward single-lamp control reflects an evolution beyond central cabinet systems. Each pole becomes a node in an IoT network.

This deal reveals that the future of smart street lighting is moving toward single lamp connectivity. This will enable granular control and tighter integration with urban data systems.

How Has Long-Join Evolved from Traditional Light Sensor Switches to Smart Lighting Solutions?

Long‑Join was founded in 2003 with a focus on ANSI C136.10-standard twist-lock, wire-in, and screw-in photocells. Over two decades, the company built a strong presence, particularly in North America. Their traditional photoelectric sensor business achieved a dominant market share in that region.

Transition from Conventional to Smart Dusk-To-Dawn Photocells

Long-Join extended its portfolio beyond basic sensores de fotocélula de luz into smart lighting control. It developed smart photocells using protocols such as ZigBee e LoRa, enabling remote monitoring and data collection.

This evolution allowed real-time light status, dimming control, and networked operation — moving from simple on/off triggers to full smart devices.

Long-Join’s NB-IoT Photocontrol Receptacle’s Lineup

The launch of the JL-245CN NB-IoT smart dimming light sensor marked the company’s entry into narrowband IoT connectivity. Key features include:

• 0-10 V dimming
• Operating temperature range between -40 °C and +70 °C
• Supports wireless communication
• Remote operation
• Real-time data feedback
• Global compliance like UL, CE, and IEC

Here is a table offering a comparison of key Long-Join NB-IoT Models

Feature	JL-245CN	JL-246CN	JL-247CN
Communication Protocol	NB-IoT, LTE-Cat1	NB-IoT, LoRa	NB-IoT, ZigBee
Dimming Range	0–10V	0–10V	0–10V
Operating Temp Range	-40°C to +70°C	-40°C to +65°C	-35°C to +70°C
Surge Protection	6kV/3kA	6kV/3kA	6kV/3kA
Global Certifications	UL, CE, IEC	UL, CE	UL, CE, Zhaga

Deployment of Long-Join’s NB-IoT Products

Long-Join’s NB-IoT controllers have found application in municipal and EPC projects. They deliver measurable benefits: energy savings, predictive maintenance, and remote management through cloud-connected systems.

These deployments reflect the shift toward single-lamp monitoring and networked street-lighting infrastructures.

What Are the Key Technical Advantages Behind Long-Join’s NB-IoT Smart Controllers?

Long‑Join markets its JL-245CN NB-IoT controller with full global standard compliance. The device:

• Supports NEMA/ANSI C136.41 interfaces
• Meets UL 773 specifications and
• Compatible with Zhaga Consortium standards

The controller offers 0-10 V dimming output and on/off scheduling for individual poles. These features enable precise control and efficient operation across entire lighting networks.

NB-IoT connectivity ensures wide-area coverage and low power consumption—only 1.2 W static. This makes large municipal rollouts more cost-effective and energy-efficient.

Built-in protection is robust. A 6 kV/3 kA surge arrestor shields the circuit. The IP67 enclosure guards against dust and water. The unit operates reliably from -40 °C to +70 °C, ideal for demanding outdoor environments.

Flexibility is another advantage. Alongside NB-IoT, the same platform supports almost all other communication protocols. This multi-protocol design allows deployment across diverse network ecosystems.

The table below compares these protocols in detail.

Protocolo	Coverage Area	Consumo de energia	Typical Applications	Advantages
NB-IoT	Wide	Baixo	Single-lamp street lighting	Reliable, scalable, and low-cost
LoRa	Médio	Baixo	Municipal area networks	Long-range, low maintenance
ZigBee	Short	Baixo	Campus, small city blocks	Fast deployment, mesh network
LTE-Cat1	Wide	Moderate	Utility-integrated smart lighting	High bandwidth, stable data

How Is the Global Lighting Market Evolving After the Signify And Telensa Deal?

The global smart street lighting market is projected to rise from $2.04 billion in 2021 to $8.23 billion by 2029. Key trends:

• Rapid adoption of LPWA technologies for smart lighting systems.
• Shift from simple group-control to single-lamp intelligence, enabling each pole to be individually managed.
• Greater integration of telecom infrastructure and IoT platforms — smart street lamps are becoming nodes in urban IoT networks.

UK Market Transitioning Toward NB-IoT Lighting Systems

The UK has been an early adopter of smart street lighting, with numerous deployments by local councils using platforms from Telensa. With Signify acquiring Telensa, NB-IoT and Talq-compliant technologies gain a stronger foothold in the UK market.

This opens opportunities for companies like Long‑Join with CE/UKCA-certified NB-IoT LED street light photocells to retrofit municipal lighting and EPC projects in the UK.

Long-Join Strengthening Its Position in the US Market

Long-Join already holds a commanding position in the US photocell market (≈ 50 % market share) in traditional devices. Building on this base, it is positioned to serve the rising demand for single-lamp control plus CMS integration in North America.

Future roadmap for Long-Join includes tighter alignment with local CMS platforms and utility-led smart lighting initiatives — especially as municipalities upgrade to NB-IoT-enabled street lighting.
