Impervia LED

An IP65 rated LED luminaire offering impressive performance and energy savings over its fluorescent equivalent. PIR or microwave sensor options offer presence detection control.


Set to revolutionise the way lighting designers think about areas requiring an IP65 rating, such as freezers and under canopy applications, the Impervia LED offers a single Fortimo LLM module to produce impressive performance up to and beyond its fluorescent equivalents.  Adding one of two sensor types, either PIR or microwave, the Impervia LED can be programmed to switch on when presence is detected and either switch off or dim during periods of absence.  The integral 3w LED emergency completes the suite of available options.
