Engineered with reliable LED technology and a maintenance-free NiCd battery, this thermoplastic unit delivers 90 minutes of emergency egress lighting while consuming minimal energy during normal operation.
The compact dual-head design mounts quickly to walls or ceilings, making the lithonia lighting elm2l ideal for corridors, stairwells, exit routes, and commercial spaces where dependable emergency lighting is required. We’ve designed it for straightforward installation and decades of reliable service with minimal maintenance.
- Dual adjustable LED lamp heads provide directional emergency illumination
- Maintenance-free sealed NiCd battery supplies 90 minutes runtime per code
- Energy-efficient LED technology reduces operating costs versus incandescent models
- Compact thermoplastic housing resists impact and mounting stress
- Universal 120/277V AC input works with standard commercial electrical systems
LED Technology & Battery Performance

The lithonia lighting elm2l utilizes energy-efficient LED lamp heads that consume significantly less power than traditional incandescent emergency lights while delivering superior lumen output. Each adjustable head directs light precisely where egress codes require, eliminating dark spots in exit paths.
Our maintenance-free nickel-cadmium battery charges automatically during normal AC operation and provides a full 90 minutes of emergency illumination when mains power fails. The sealed battery design eliminates the maintenance burden of checking water levels or cleaning terminals, reducing your facility’s long-term operating costs.
Installation & Mounting Specifications

We’ve designed the ELM2L M12 with a universal mounting plate that accommodates both wall and ceiling installations without requiring additional hardware. The compact 13.5″ width fits standard electrical box spacing, and the thermoplastic housing weighs just 4.2 pounds for easy single-person installation.
The unit accepts 120V or 277V AC input automatically, eliminating the need to specify voltage during ordering or configure field settings during installation. Standard ½” knockouts on the housing back plate simplify conduit connections, and the hinged door provides tool-free access to wiring terminals.
Housing Construction & Environmental Rating

The injection-molded thermoplastic housing resists impact, UV exposure, and the thermal cycling common in mechanical rooms and unheated spaces. Unlike metal housings that corrode in humid environments, our thermoplastic design maintains structural integrity and appearance for decades in warehouses, parking structures, and exterior canopies.
All electrical components mount to a steel chassis inside the housing, providing rigid support that prevents wire fatigue and connector loosening during building vibrations. The chassis also serves as a heat sink, extending LED and battery life by dissipating operating heat away from sensitive components.

Common Questions About the ELM2L M12
The sealed nickel-cadmium battery in the ELM2L M12 typically maintains full 90-minute capacity for 7 to 10 years under normal operating conditions with proper charging cycles. Battery life varies based on ambient temperature, charge/discharge frequency, and operating environment.
We recommend annual 90-minute duration tests to monitor battery performance over time. When test results show runtime dropping below code-required 90 minutes, the battery should be replaced with a genuine Lithonia replacement unit to maintain UL listing and warranty coverage.
The standard ELM2L M12 carries a dry location rating suitable for indoor commercial applications including corridors, stairwells, mechanical rooms, and covered loading docks. The thermoplastic housing resists humidity and temperature cycling but is not sealed against direct water exposure.
For outdoor installations, parking garages, or areas with moisture exposure, we recommend our Quantum series wet location emergency lights that feature sealed housings and weatherproof lamp head gaskets. Our technical support team can help specify the appropriate model for your specific environmental conditions.
Each adjustable LED lamp head on the ELM2L M12 delivers approximately 1.5 watts of LED power, providing sufficient illumination for egress path lighting as required by NFPA 101 Life Safety Code and IBC emergency lighting standards. The dual-head configuration allows directional coverage of corridors, stairwells, and exit routes.
Actual illumination levels at floor level depend on mounting height, head angle, and room geometry. For spaces requiring specific footcandle measurements or complex coverage analysis, we offer photometric layouts through our specification services to ensure code compliance before installation.
Yes, the lithonia lighting elm2l accepts both 120V and 277V AC input automatically without requiring voltage selection switches or field configuration. The universal voltage charging circuit detects input voltage and adjusts battery charging parameters accordingly, simplifying specification and installation.
This dual-voltage capability makes the ELM2L M12 ideal for commercial facilities where emergency lights connect to 277V lighting circuits rather than 120V receptacle circuits. Simply connect to your available voltage using appropriate wire gauge per NEC requirements and the unit operates correctly.
Monthly 30-second tests require simply pressing the test switch on the ELM2L housing to disconnect AC power and verify both LED heads illuminate. The green charge indicator LED extinguishes during the test and returns when you release the switch, confirming proper operation. Document the test date and results per your facility’s compliance procedures.
Annual 90-minute duration tests follow the same procedure but require holding the test switch in the test position for the full code-required period while timing the illumination. Most facilities use a test switch guard or screwdriver to maintain switch position during the extended test. Both heads should remain illuminated for at least 90 minutes before the battery depletes.
The ELM2L M12 supports up to two additional remote LED heads using our ECR series remote head kits, allowing you to extend emergency coverage up to 100 feet from the main unit without installing additional battery packs. Remote heads connect via low-voltage wiring and draw power from the ELM2L’s battery during emergencies.
For applications requiring more than four total LED heads or coverage beyond 100 feet, we recommend installing additional complete ELM2L or ELM4L units, or specifying a central inverter system that powers multiple standard fixtures from a centralized battery bank. Our specification team can design the optimal configuration for your facility layout and coverage requirements.
We provide a comprehensive 5-year warranty covering defects in materials and workmanship on the ELM2L M12 housing, LED lamp heads, charging circuit, and battery. The warranty begins from the date of purchase and covers replacement parts and technical support for manufacturing defects.
The warranty requires proper installation per NEC and manufacturer instructions, operation within specified voltage and temperature ranges, and routine testing per NFPA requirements. Physical damage, improper wiring, or use of non-genuine replacement parts void warranty coverage. Register your product within 60 days of installation to ensure full warranty protection and access to technical support resources.
