LFI Lights Compact Green Exit Sign With Emergency Lights
This all-LED exit sign uses an light pipe and adjustable light bar for even illumination. It is UL 924 listed and damp-location rated, suitable for interior spaces that require NEC, OSHA, and NFPA 101 compliance. It runs on 120/277 VAC and consumes around 5 watts, providing more than 90 minutes of emergency light via two 4.8V 1000mAh NiCad batteries. The housing is 5VA flame-retardant thermoplastic. It is best for small retail spaces, offices, or lobbies where a compact, wall- or ceiling-mountable unit is needed. Caution: the unit’s light output is designed for standard egress paths; in unusually large or complex layouts, additional signage may be required for full visibility.
Best for: Small facilities that need a compact, energy-efficient, battery-backed exit sign with dependable emergency duration. Better for areas with damp locations and horizontal mounting constraints.
Accuform PSP221 Projection Sign 90D
The Accuform PSP221 provides a projection-style exit message with 90D visibility. Its 8″ x 12″ high-impact plastic panel features dual-sided lettering for improved view from multiple angles, making it ideal for corridors or intersection points where sightlines can vary. Pre-drilled mounting holes simplify installation. This sign does not specify an internal power backup, so ensure your system’s power design accommodates needed accessibility and compliance. Caution: verify mounting clearance and viewing distance for your specific corridor width.
Best for: Hallways or entry points where dual-side projection improves visibility for pedestrian traffic. Choose this if you need convincing legibility from multiple angles and straightforward mounting.
LFI Lights Thin Exit Sign With Battery Backup
This slim exit sign is designed for tight spaces and side or ceiling mounting. It runs on 120-277 VAC with only 1.6 watts of consumption and a 1.2V 1000mAh NiMH battery that ensures more than 90 minutes of emergency lighting. The white thermoplastic housing is UL 94 V-0 rated and damp-location suitable. It includes a push-to-test LED indicator for easy verification. Caution: watch for environments with extremely bright ambient lighting, which can impact perceived brightness in some installations.
Best for: Tight corridors or rooms with limited headroom where a very low-profile exit sign is preferred. Better for installations requiring a battery-backed option without bulk.
2 Pack Left Arrow Exit Sign (18″ x 18″)
These large, weatherproof aluminum exit signs feature a bold left-pointing arrow and the word EXIT in contrasting black. The reflective coating enhances visibility in low-light or nighttime conditions, making them suitable for parking lots, warehouses, and outdoor indoor transitions. The aluminum construction is rust-resistant, ensuring longevity in harsh weather conditions. Caution: outdoor durability is strong, but be mindful of reflectivity requirements in areas with direct vehicle glare or high-LED ambient lighting, which may affect readability at distance.
Best for: Parking lots, loading docks, and outdoor-adjacent interiors requiring highly visible, rust-free signs with directional clarity.
Lithonia Lighting Single-Sided LED Exit Sign
The Lithonia EXRG LED exit sign delivers a switchable red/green color option in a classic, durable thermoplastic housing. It includes a Ni-MH backup battery and an extra faceplate for flexible messaging. Mounting versatility is high, with top, side, or back mounting capabilities and compatibility with most standard junction boxes. It is intended for indoor damp locations and operates within a typical temperature range for many commercial spaces. Caution: switching colors requires proper wiring and adherence to local wayfinding color standards where applicable.
Best for: Spaces needing flexible color coding for wayfinding and easy retrofitting into existing junction boxes. Better for interiors with damp-location requirements and variable mounting orientations.
Buying Guide
What mounting option should I choose?
Side-mount or wall-mount signs are ideal for corridors, hallways, and rooms where visibility is best from a lateral perspective. If ceiling mounting is preferred, look for models that explicitly support ceiling and side mounting, or consider signs with adjustable light bars to optimize path illumination.
What about battery backup and run-time?
Consider how long the sign can provide illumination during an outage. Signs with >90 minutes of emergency light are common and adequate for many facilities. Battery chemistry (NiCad or Ni-MH) affects long-term performance and replacement schedules.
How important is UL 924 and life-safety compliance?
UL 924 listing ensures a signaling device meets essential safety standards for emergency lighting and exit signage. For facilities in regulated industries, verify compliance with NFPA 101, NFPA 70, NEC, and OSHA requirements as applicable to your locality.
What materials and durability matter?
Thermoplastic housings offer lightweight durability, while aluminum signs provide rugged, weather-resistant performance for outdoor or exterior-adjacent applications. For damp locations, ensure the device is rated accordingly.
Do I need dual-face or single-face messaging?
Dual-face signs are advantageous where both sides of a corridor require visibility. If space is constrained or wall space is limited, single-face with a clear line of sight to the main thoroughfares may suffice. Look for options offering optional faces or directional arrows as needed.
What installation considerations influence selection?
Check mounting patterns, canopy compatibility, and whether a sign supports top, side, or back mounting. Ensure the chosen unit matches your electrical supply (120V vs 277V) and that the installation complies with local electrical codes.

FAQ
- What does UL 924 certification mean for my exit signs?
UL 924 indicates the sign meets standard requirements for emergency lighting and signage used during power outages. It helps confirm reliability in life-safety scenarios.
- Can these signs be used in damp or humid locations?
Yes, most listed options offer damp-location ratings. Verify the product’s specific environmental rating before installation.
- Do these signs require batteries?
Several models include internal battery backup to maintain illumination during outages. Some may rely on external power with no battery backup.
- Is a dual-face exit sign always better than a single-face sign?
Dual-face signs improve visibility from multiple directions, especially in longer corridors or crossroads. In tight spaces, a well-placed single-face with clear sightlines can suffice.
- Are spare faces or replacement parts available?
Many manufacturers offer replacement faceplates or optional dual-face configurations. Check compatibility with your exact model when planning upgrades.
- What is the recommended mounting height for exit signs?
Recommended mounting height is typically around 7 to 8 feet above grade, depending on aisle width and sightlines, to ensure legibility from the required distance.
