Lithonia LQM LED Exit Sign
Our LQM LED exit sign provides code-compliant emergency egress marking with advanced LED technology that delivers decades of maintenance-free operation. Designed for commercial, institutional, and multi-family applications, this exit sign combines universal mounting versatility with crisp, high-visibility lettering that remains clearly legible from required viewing distances.
The lithonia lighting lqm series features a thermoplastic housing that resists impact and UV degradation while maintaining its appearance in high-traffic environments. Energy-efficient LED arrays eliminate the lamp replacement cycles and heat output associated with incandescent models, reducing both operating costs and facility maintenance requirements over the life of the fixture.
- Energy-efficient LED technology with 25+ year rated life eliminates bulb replacements
- Universal knockout mounting pattern fits standard single-gang, double-gang, and 4-inch octagonal electrical boxes
- Thermoplastic housing resists impact, moisture, and UV degradation in demanding commercial environments
- Red or green LED exit legends available with crisp, high-contrast visibility from code-required viewing distances
- 120/277V dual-voltage input accommodates most commercial electrical systems without additional transformers
LED Technology & Energy Performance

The lithonia lighting lqm utilizes long-life LED arrays that draw less than 5 watts during normal operation, delivering significant energy savings compared to traditional incandescent exit signs that consume 15-40 watts. This reduction in power consumption translates to lower utility costs and reduced HVAC load, as LEDs generate minimal heat during operation.
Rated for 25+ years of continuous use, the LED light source eliminates the recurring expense and labor associated with lamp replacement programs. The solid-state design withstands vibration and shock better than filament-based alternatives, making it ideal for environments with mechanical equipment or high foot traffic.
Installation & Mounting Flexibility

Universal Electrical Box Compatibility
Our LQM features a rear-panel knockout pattern that aligns with standard single-gang, double-gang, and 4-inch octagonal electrical boxes, eliminating the need for specialized mounting hardware or adapter plates. The universal design allows electricians to install the sign using existing junction box infrastructure, reducing installation time and material costs.
Dual-Voltage Input
The 120/277V input accepts the most common commercial voltage configurations without requiring external transformers or step-down devices. This dual-voltage capability simplifies specification and inventory management for facilities with mixed electrical systems, while reducing points of potential failure in the circuit.
Housing Construction & Durability

The thermoplastic housing resists impact from carts, equipment, and accidental contact in busy corridors and loading areas. Unlike painted metal enclosures that chip and rust, the injection-molded construction maintains its appearance without refinishing, even after years of exposure to cleaning chemicals and UV light from adjacent windows.
The material formulation meets UL94 flammability ratings and does not emit harmful off-gassing, making it suitable for healthcare facilities, schools, and other environments with stringent indoor air quality requirements. Sealed lens panels prevent dust and insects from entering the housing and obscuring the exit legend.

What people are saying









Questions About the Lithonia LQM LED Exit Sign
The LED arrays in the lithonia lighting lqm are rated for over 25 years of continuous operation under normal ambient conditions. This eliminates the recurring lamp replacement cycles required by incandescent and fluorescent exit signs, reducing long-term maintenance costs and labor.
The solid-state LED design maintains consistent brightness throughout its service life, unlike gas-discharge lamps that gradually dim as they age.
Yes, the LQM features a universal knockout pattern on the rear panel that aligns with standard single-gang, double-gang, and 4-inch octagonal electrical boxes. This versatility eliminates the need for specialized adapter plates and allows installation using existing junction box infrastructure in most commercial buildings.
The mounting design accommodates both new construction and retrofit applications without requiring modifications to the wall or ceiling substrate.
Battery-equipped LQM models provide a minimum of 90 minutes of emergency illumination during AC power loss, meeting or exceeding the duration specified in NFPA 101 Life Safety Code Section 7.9 and International Building Code requirements for exit sign emergency operation.
The battery automatically recharges when utility power is restored, ensuring the sign remains ready for subsequent outages. Self-diagnostic models test the battery capacity monthly and annually to verify ongoing compliance.
The lithonia lighting lqm accepts both 120V and 277V AC input without requiring external transformers or voltage conversion devices. This dual-voltage capability allows installation on either standard 120V branch circuits or 277V high-leg delta systems common in larger commercial facilities.
Electricians can wire the sign to whichever voltage is most convenient at the installation location, simplifying multi-building projects where electrical system voltages may vary between structures.
Self-diagnostic LQM models automatically perform a 30-second function test monthly and a full 90-minute discharge test annually, as required by NFPA 101 Section 7.9.3. Front-panel LED indicators display pass/fail status, eliminating the need for manual testing by facility staff.
When the system detects a fault—such as battery degradation, LED circuit failure, or charging system malfunction—the diagnostic indicator changes color or blinks to alert maintenance personnel that service is needed.
The LQM measures approximately 12.5 inches wide, 8.5 inches high, and 2 inches deep, providing a low-profile installation that minimizes protrusion from walls and ceilings. The compact depth is especially valuable in tight plenum spaces and historic buildings with shallow wall cavities.
The housing dimensions accommodate standard exit letter height requirements while maintaining a clean, unobtrusive appearance suitable for finished architectural environments.
Yes, we offer the lithonia lighting lqm with either red or green LED exit legends to accommodate local jurisdiction preferences and international building code variations. Both colors provide high-contrast visibility from code-required viewing distances and maintain consistent brightness over the LED’s rated service life.
Red legends are standard in most U.S. jurisdictions, while green options are increasingly specified in facilities pursuing international building certifications or aligning with global safety standards.
