LED Linear Explosion Proof Lights – ATEX Certified

LU Series

Developed by SEEKINGLED for Zone 2 (gas) and Zone 22 (dust) hazardous locations, the LU Series is a slim, high-performance LED linear explosion proof lights solution.
Its smooth, easy-to-clean surface makes it particularly suitable for oil & gas, equipment machine rooms, and similar hazardous area lighting applications where hygiene and durability are essential.
Power Options and Versatility

Six power choices available:
Short model: 40W, 60W, 80W
Long model: 75W, 100W, 150W

Fully replaces traditional explosion proof fluorescent lighting at low mounting heights (up to 5 metres), with up to 22,000 lumens for effective high-bay illumination above 10 metres.
Advanced LED technology ensures high energy efficiency, 150LM/W@CRI80,a service life of 100,000 hours, and minimal maintenance requirements.

Robust Protection
IP69K (highest level of water and dust protection – withstands high-pressure, high-temperature washdowns)
IK10 impact resistance (20 joules)

Engineered for reliable performance in demanding industrial environments.
Cost-Saving and Practical Design
Integrated explosion proof junction box eliminates the need for separate certified boxes, significantly reducing project costs.
Built-in DIP switch allows on-site adjustment across three power levels: 100% – 75% – 50% – one luminaire covers multiple requirements, greatly simplifying distributor inventory and reducing the number of SKUs required.
Certification
Genuine ATEX certificate issued by TÜV – full compliance in Europe and all regions recognising ATEX standards.

FAQs – LED Linear Explosion Proof Lights – LU Series

What type of hazardous areas is the LU Series designed for?

The LU Series LED Linear Explosion Proof Lights are designed for Zone 2 gas and Zone 22 dust hazardous locations. It is typically used in areas where explosive atmospheres are present occasionally rather than continuously.

Can LU Series replace traditional explosion proof fluorescent lights?

Yes. In most projects, this explosion proof led linear lighting replaces fluorescent fixtures directly, especially at mounting heights up to 5 meters. In higher installations, higher wattage models can be used to achieve sufficient illumination.

What is the main difference between the short and long models?

Short models (40W / 60W / 80W) are mainly used for corridors, equipment rooms and low ceilings.
Long models (75W / 100W / 150W) are used in larger spaces and can also serve as explosion proof led lights linear for high mounting positions above 10 meters.

Is the LU Series suitable for washdown areas?

Yes. The housing is rated IP69K. This explosion proof linear led lighting can withstand high-pressure and high-temperature water cleaning, which is common in oil & gas and industrial processing areas.

Does the fixture require an external explosion proof junction box?

No. The LU Series comes with a built-in explosion proof junction box, which reduces installation time and avoids the need for additional certified accessories.

How does the power adjustment function work?

Each fixture includes a DIP switch that allows three power settings: 100%, 75% and 50%. This helps distributors and project contractors reduce SKUs while keeping flexibility on site.

What impact resistance level does the product have?

The housing meets IK10 (20J). This makes the explosion proof led linear light suitable for industrial environments where mechanical impact or vibration is expected.

What LED performance can be expected over time?

At 25°C ambient temperature, the LU Series reaches L80B20 over 100,000 hours. This means long service life and reduced maintenance, which is important in hazardous zones.

Can multiple fixtures be wired in series?

Yes. Two M20 cable entries allow series installation. This feature is often used in continuous explosion proof led bar linear lighting layouts.

Is the LU Series officially certified for ATEX projects?

Yes. SEEKINGLED provides a genuine ATEX certificate issued by TÜV, covering both gas and dust classifications required for European and ATEX-recognized markets.
