Polaris level indicator light

The Polaris LED lighting system is designed for the marine, land-based, and offshore industries where level gauges are needed. They are suitable for environments with high humidity or explosive atmospheres. LEDs are digital lights and have several advantages compared to conventional «analog» lighting, making them arguably the most energy-efficient and environmentally friendly technology for lighting. Some of the major advantages of LED lighting are:

• Longevity
• Energy efficiency
• Environmentally friendly
• Durable quality
• Operational in extremely cold and hot temperatures

Polaris comes in stainless steel (316SS) with ATEX and IECEx certification (Ex mb IIC T4 Gb). They can withstand a wide temperature range (-30°C to +70°C) and have IP67 protection. The level indicator lights can be supplied in any length from 250mm to 2500mm with 50mm intervals. It is also possible to connect two lights together to achieve a maximum length of 5000mm. Polaris comes with a junction box or flying lead. The junction box is Ex eb IIC T4 Gb / Ex tb IIIC T135°C Db with IP67.
