LED tubular light fitting designed for use in extremely rough conditions.

Conventional linear luminaires are ill-equipped to withstand extreme temperatures and harsh environments, much less for long periods of time – LED tubular lights from R. Stahl's 6036 series, however, are quite a different calibre. They tolerate temperatures as low as -55 °C and are therefore suitable for applications such as LPG exploration in the Arctic region. On the other end of the spectrum, they withstand heat up to +60 °C, and also tolerate extreme temperature fluctuations.

The lights are available with an IP66, IP67, or IP68 ingress protection rating, suitable also for maritime applications. They are vibration-proof and impact-resistant up to IK 10. Available in 0.75 m, 1.1 m, and 1.4 m versions, these durable units feature a nominal lifespan of 80,000 hours. While their design is very rugged, the LED tubular lights are absolute lightweights – their maximum weight of 2.45 kg amounts to less than half that of comparable linear luminaires. The low-maintenance products are suitable for general lighting purposes or for use as machine lamps. Due to their slim design, they are easy to install even in hard-to-access locations.

In addition, the 6036 series is extraordinarily light-efficient: the overall power consumption is only about half that of conventional box-type units and the specific power consumption per 100 lx is merely 1.5 W/m². Operating expenses are therefore greatly reduced – realistic cost savings range from some 20% to more than 50%, depending on the relevant time frame and specific solutions that are compared. In addition to ATEX and IECEx certificates for zones 1/21 and 2/22, the lights feature various regional approvals for many major markets (EAC TR CU, Gazpromnadzor, UL do Brasil, GL).

The versatility of the series is further enhanced by the choice of connection cables: while H07RN-F is the default, users can also choose Thermflex, low-temperature, special offshore cables, or cables that are high-voltage-proof up to 1 kV. The lightweight products’ durability in extreme conditions is also captured on video by the “R. Stahl Explorers”, whose website www.stahl-explorers.com also presents background information on LED technology and news about lighting solutions.
