The long-life LED technology eliminates lamp replacement hassles while the self-diagnostic system ensures code compliance with automated testing functionality.
- Dual adjustable LED lamp heads for targeted emergency illumination coverage
- Energy-efficient LED technology with 10+ year operational lifespan
- Maintenance-free sealed lead-acid battery provides 90-minute emergency runtime
- Universal mounting bracket for wall or ceiling installation flexibility
- Self-diagnostic testing with push-to-test button and status indicator lights
LED Lamp Head Configuration & Mounting
The lithonia lighting elm4l features two fully adjustable LED lamp heads mounted on articulating pivots that rotate and tilt to direct emergency illumination exactly where it’s needed. Each lamp head houses multiple high-output LEDs that provide focused beams covering egress pathways, stairwells, and exit corridors.
Universal Installation Options
Our engineers designed the ELM4L with a universal mounting bracket that adapts to wall or ceiling surfaces using the included hardware. The unit installs above doorways, at corridor intersections, or in open areas requiring emergency coverage. The low-profile thermoplastic housing measures just 3.5 inches deep, allowing flush installation against most architectural surfaces without protruding into circulation paths.
Battery Backup System & Runtime Performance
A maintenance-free sealed lead-acid battery powers the lithonia lighting elm4l during utility outages, delivering reliable 90-minute emergency runtime that meets code requirements for safe egress. The battery charges automatically from normal AC power and maintains full capacity through our temperature-compensated charging circuitry.
The self-diagnostic system continuously monitors battery health and charging status, with LED indicators displaying operational readiness at a glance. A push-to-test button allows facility managers to verify emergency function without interrupting normal power, while the automatic monthly self-testing feature reduces manual inspection requirements.
Code Compliance & Testing Features
The ELM4L emergency light meets NFPA 101 Life Safety Code requirements, NEC Article 700 emergency system standards, and UL 924 listing for emergency lighting equipment. These certifications ensure the unit performs reliably during power failures and satisfies building code inspections across all 50 states.
The integrated self-diagnostic circuitry performs automatic 30-day function tests and annual 90-minute discharge tests, maintaining detailed logs of system performance. Status indicators alert facility managers to any battery, lamp, or charging issues requiring attention. The manual test button provides on-demand verification between automated test cycles.

ELM4L Emergency Light Questions
The ELM4L provides 90 minutes of emergency illumination on battery backup, meeting NFPA 101 Life Safety Code requirements for safe building egress. The maintenance-free sealed lead-acid battery recharges automatically from AC power and maintains full capacity through temperature-compensated charging circuitry.
The self-diagnostic system performs annual 90-minute discharge tests to verify the battery maintains adequate runtime throughout its 5-7 year service life.
Yes, the universal mounting bracket accommodates wall or ceiling installation using the included hardware. The unit installs above doorways, at corridor intersections, or in open areas requiring emergency coverage.
The adjustable LED lamp heads provide 180-degree horizontal rotation and 90-degree vertical tilt, ensuring optimal light distribution regardless of mounting location or height. Standard electrical knockout entries accept conduit from multiple directions for installation flexibility.
The LED lamp heads require no bulb replacements during the unit’s operational lifespan, typically 10+ years of service. LED technology eliminates the ongoing maintenance burden and replacement costs associated with incandescent emergency lights.
Quarterly visual inspections verify proper operation through status indicators, while the self-diagnostic system alerts you to any lamp failures. The sealed LED modules maintain consistent light output without degradation over time.
The integrated self-diagnostic circuitry performs automatic 30-day function tests and annual 90-minute discharge tests, maintaining operational readiness without manual intervention. LED status indicators display test results and alert facility managers to any battery, lamp, or charging issues.
A manual push-to-test button provides on-demand verification between automated cycles. The system maintains test logs that satisfy fire code inspection requirements and reduces the burden on facility maintenance staff.
The ELM4L meets NFPA 101 Life Safety Code requirements, NEC Article 700 emergency system standards, and carries UL 924 listing for emergency lighting equipment. These certifications ensure code compliance across all jurisdictions and satisfy building inspection requirements.
The unit also complies with California Title 24 energy standards and qualifies for installation in projects requiring energy-efficient emergency lighting solutions. Detailed specification sheets are available for submittal during permitting and plan review.
The sealed lead-acid battery typically provides 5-7 years of reliable service before replacement becomes necessary, depending on ambient temperature and discharge frequency. The self-diagnostic system monitors battery health continuously and alerts you when replacement is required.
Replacement batteries are available through authorized Lithonia Lighting distributors. The front-accessible battery compartment allows replacement without removing the entire unit from its mounting location, minimizing downtime during maintenance.
The ELM4L operates reliably in ambient temperatures from 32°F to 104°F (0°C to 40°C), suitable for most interior commercial environments including warehouses, offices, retail spaces, and institutional facilities.
The thermoplastic housing protects internal components from temperature fluctuations while the temperature-compensated charging circuitry adjusts battery charging rates to maintain optimal performance across the operating range. Units installed near exterior doors or in unconditioned spaces should verify local temperatures remain within specifications.
