STL International Ltd is a lighting solution provider, offering a wide range of low maintenance and hazardous area LED luminaires with high performance levels.

The ongoing mission for STL is to eliminate, or at least drastically reduce, lighting maintenance so that skilled and valuable personnel time can be spent more productively elsewhere on the plant or site. We achieve this with the use of high quality LED modules alongside long lasting materials and components from reputable suppliers.

The EXTRA-N-LED linear range for zone 2/22 has been fitted with a new generation of LED modules. Due to the improved efficacy of the modules, up to 155lm/W, the 5ft versions are now available with an incredible lumen output in excess of 16,300lumen and can be fitted with special optics for aisle applications. This means that the EXTRA range of LED luminaires now offers new opportunities in high ceiling applications in hazardous area. Some of the luminaires can be used in ambient temperatures of up to 60°C.

The new modular BERGER-N-LED range of zone 2/21 flood/high bay lighting is available with a lumen output of up to 43,650 lumen. A variety of different optics and LED drivers means that the fittings can be adapted for most applications, including ambient temperatures of up to 70°C.

Another new addition to our hazardous area range is the BORDER-N-LED range of zone 2/21 recessed luminaires, ideal for cleanroom applications. Designs are available for different ceiling grid sizes and plasterboard. 

In addition, the hazardous area range can be supplied with Bluetooth MESH wireless control modules, dimmable DALI drivers and DALI emergency inverters, 1-10V dimmable drivers, Auto-test emergency inverters, Microwave sensors as well as drivers which are dimmable when operating on the DC voltage of a Central Battery.

To complement the range of hazardous area lighting and to provide added flexibility, independent zone 1/21 microwave and photocell switches are also available. The microwave switches are suitable for heights of up to 12m as well as for DALI control systems.

Other LED luminaires are available for specialist applications such as extreme temperatures, up to 75°C, impact resistant of up to 120J (5kg@2.8m), silicone free for paint booths and anti-ligature for prisons and secure healthcare facilities.
