Description
The LINKEx™ LX-400 LED temporary lighting lamp is ATEX certified for use in potentially explosive atmospheres. The LED lamp is used in short-term lighting installations for maintenance tasks and is CE marked according to the ATEX Directive and IECEx certified for safe use in zones 1 and 2 with potentially explosive gas and dust atmospheres, where a temperature class T3/T4 (depending on the variant chosen) allows.
Available in two versions (choose the desired version when ordering; price varies depending on the version), with different brightness, power and temperature class:
- T4 Low and high voltage (LV and HV)
- T3 High Voltage (HV)
The LinkEx™ LED Temporary range offers high quality lighting. Each lamp uses two high-power LED arrays that provide bright white light, which are highly reliable and are a "lifetime" light source, with low maintenance, allowing for energy savings, longer cables and powering multiple similar lamps from a single source.
The luminaires are available as standard in 180° format (mounting in rows side by side) to provide efficient unidirectional lighting or optionally in 360° format (mounting in rows back to back), to provide efficient omnidirectional lighting. ATEX and IECEx certified for use in zones 1 and 2 (explosive gas and dust atmospheres), it features the unique SOVI™ (Safe Optimal Voltage Indicator) system:
- T4 - the beam will pulse to indicate if the lamp is not at optimum performance voltage. Safe for 0 volt supply.
- T3 HV - has a colored LED indicator to confirm that the lamp is operating safely
