TANLUX Red Exit Sign With Emergency Lights

This sign uses a thermoplastic housing with UL-94V-0 flame retardant material. It features bright red EXIT lettering and an LED emergency light visible from up to 100 feet. The built-in Ni-Cd 3.6V battery provides about 90 minutes of operation during power outages and supports safe charging. It operates on universal 120V-277V AC, suitable for many commercial settings and outdoor/indoor use. Best for: spaces that require a robust, all-in-one unit with a reliable emergency battery backup.
Best for businesses needing strong visibility and a straightforward installation. A potential limitation is the need to manage mounting hardware, as mounting parts are inside the housing and must be opened before installation. Consider this sign if you value a compact, battery-backed solution in standard commercial voltages.
Lithonia Lighting Single-Sided LED Exit Sign

This exit sign uses a white thermoplastic housing and a single face with an internal switch to choose red or green for direction. It includes a Ni-MH backup battery and an extra faceplate. It’s UL Listed and designed to meet NFPA 101, NEC, and OSHA standards, making it suitable for indoor damp locations. Best for: facilities that require flexible color indication and easy updating of directional chevrons.
Limitation to note: damp-location suitability is indoors only, and the unit’s mounting pattern fits most standard junction boxes. Choose this if you want adaptable color direction and standard-compliance in a compact form.
Amazon Basics LED Emergency Exit Sign

This model features a double-face exit sign housed in fire retardant, injection-molded thermoplastic ABS. It supports wall, ceiling, and end mounting with 120/277VAC input. It uses Epstar SMD LEDs with a test switch and a charge indicator, ensuring visibility from both sides. Best for: cost-conscious installations that require reliable dual-face visibility and common electrical compatibility.
One caveat: as a hardwired unit with battery backup, it will require proper electrical wiring during installation. Choose this for predictable performance and a familiar brand in standard office environments.
NightBright USA Photoluminescent Exit Sign

This option uses no electrical wiring and relies on photoluminescence charged by ambient light. It’s UL 924 listed and requires no battery or power source. Best for: spaces with limited electrical access or as a supplemental safety sign where electricity isn’t feasible. A limitation is that brightness depends on ambient light exposure, which may reduce visibility in dark areas.
TANLUX Red Exit Sign With 1.0 Meter Plug-In Cord

This plug-in variant offers a red exit sign with a 1.0-meter cord and battery backup. It provides up to 100 feet visibility and uses a Ni-Cd 3.6V battery for at least 90 minutes of operation during outages. It supports top, side, and back mounting, with canopy included for versatile installation. Best for: spaces where a plug-in design minimizes electrical work while still providing backup power. Limitation: corded setup may require accessible outlet placement and may impact installation aesthetics in some layouts.
TORCHSTAR LED Exit Sign With Battery Backup

This double-face sign is built for damp locations with a UL 924 rating and a 1.2V 900mAh rechargeable battery that sustains operation for up to 90 minutes during outages. It provides red lettering and is designed for easy three-way mounting (side, ceiling, back wall). Best for: areas exposed to humidity or moisture where dual-face visibility improves egress. Caution: ensure proper wiring and battery maintenance per local codes, as battery backup performance depends on charging status.
Buying Guide
What type of battery backup is best for my space?
Consider sealed lead-acid or Ni-Cd/Ni-MH batteries depending on back-up duration and climate. For most commercial interiors, a 90-minute backup is standard, but some applications may require longer. Check replacement availability and expected service life for the battery type.
Which mounting options should I prioritize?
Top, side, or back mounting options offer flexibility for different ceiling heights and wall layouts. If you need canopy support for recessed ceilings or outdoor setups, ensure the model includes suitable mounting hardware and can accommodate that configuration.
How important is universal voltage versus dedicated input?
Models supporting universal 120V-277V AC are versatile in many spaces, reducing the need for transformers or separate wiring. If your building has a fixed voltage, choose a model with a compatible input and reliable back-up behavior at that voltage.
What are the considerations for dual-face versus single-face signs?
Dual-face signs improve visibility from multiple directions, which is beneficial in hallways and open-plan areas. If your layout only requires visibility from one direction, a single-face sign may be sufficient and potentially more compact or cost-effective.
Is a photoluminescent option a good backup plan?
Photoluminescent signs do not rely on electricity or batteries and can be a good supplementary measure in well-lit areas. They should not replace battery-backed signage in spaces with limited ambient light or during extended outages.
FAQ
What is the typical backup duration for battery-backed exit signs?
Most models provide about 90 minutes of operation during a power outage, supported by a built-in rechargeable battery.
Can these signs be mounted on walls, ceilings, and corners?
Many models offer multiple mounting options, including top, side, and back mounting. Check the product’s included hardware and canopy compatibility.
Do all battery-backed signs require professional installation?
Hardwired units generally require electrical wiring and should be installed by a qualified electrician. Plug-in and lightweight battery-backed units may be installed by building staff with basic electrical safety knowledge.
Are there signs that require no electrical power at all?
Photoluminescent signs do not require power but rely on ambient light to recharge. They are best used as supplementary signs where electrical backup is not required.
What certifications should I look for?
UL 924 or NFPA 101 compliance is common for exit signs. Ensure the model meets local fire and building codes and is rated for indoor damp locations if applicable.
