Pioneer in emergency tube lighting, the COULOMB has made its mark in the category of independent industrial emergency lighting units. Its high-level seal properties and the robustness of its housing endow it with exceptional resistance over time. NFAEAS-certified with automatic built-in test system, in Evacuationor Ambient version, it can be connected to a 12V remote control (see accessories) to go on idle in the event of a deliberate power outage or for scheduled automatic or manual tests.
