The Prolite PEL LED TBL (SQ) WP(1) is an industrial-grade, non-maintained emergency luminaire engineered to provide 180 minutes (+10%) of continuous autonomous illumination during mains power failures. Built with an IP65 weatherproof Polycarbonate housing finished in Grey RAL 7035 and dual 10 W directional LED heads in diecast aluminium enclosures, this emergency light addresses life-safety compliance, egress illumination, and process continuity across demanding indoor and outdoor commercial facilities.
Warehouses, Logistics Hubs, and Godowns
High-bay storage facilities, distribution centers, and godowns present vast aisle spans and elevated ceilings where general illumination failure creates critical personnel hazards. The dual 10 W adjustable LED lamp heads—powered by GMR Light, BridgeLux, Edison, or Lustrous emitters behind clear glass diffusers—can be oriented independently across perpendicular pathways or high-traffic picking lanes.
With an IP65 ingress protection rating, the unit resists heavy airborne dust and humidity commonly found in unconditioned logistical spaces. When the primary ~230 V AC power network fails, the luminaire automatically activates via its internal SLA rechargeable battery (they are not included) system, maintaining egress visibility for warehouse workers operating material handling equipment.
Railway Yards and Outdoor Transport Facilities
Railway marshalling yards, maintenance sheds, and outdoor freight terminals require emergency fixtures capable of withstanding harsh weather conditions. The white epoxy polyester powder-coated diecast aluminium lamp assemblies and sealed Polycarbonate enclosure protect sensitive components against wind-blown grit and ambient moisture.
Because the unit supports both fixed surface wall mounting (via standard 180 mm horizontal by 160 mm vertical rear mounting pitches) and portable field deployment, railway inspection and safety crews can transport the 4 kg unit directly to switch tracks or repair sidings during utility blackouts.
Underground Parking Structures and Stairwells
Subterranean facilities and multi-level parking decks lack natural daylight, making instant emergency illumination critical for life safety. Operating in non-maintained mode, the PEL LED TBL (SQ) WP(1) remains dormant on mains standby while its constant voltage charger maintains the SLA battery (they are not included) at peak readiness.
Upon total mains disconnection, the fixture switches on instantly to illuminate concrete stairwells, ramp transitions, and pedestrian walkways for a full 3-hour duration, fully meeting IS 10322 luminaire deployment expectations.
Industrial Battery Rooms and Electrical Utility Substations
Industrial battery (they are not included) rooms, uninterruptible power supply (UPS) utility vaults, and switchgear enclosures demand robust safety fixtures to facilitate emergency monitoring during catastrophic electrical trips. The unit's electrical-grade 5 A, 250 V connector ensures reliable single-phase termination.
During a sustained outage, the internal control circuitry prevents deep discharge damage by executing an automatic cut-off at low voltage thresholds. When ~230 V power resumes, the unit immediately engages a 10 to 12 hour recharge cycle before transitioning automatically into trickle charge mode to safeguard the SLA battery (they are not included) indefinitely.
Commercial Corridors and Hotel Egress Routes
In hotels, commercial offices, and institutional dormitories, exit corridors must provide dependable passage during fire alarms or grid dropouts. The compact 355 mm x 255 mm x 122 mm form factor allows straightforward architectural wall mounting without impeding passage clearances.
