It provides not less than 90 minutes of power to up to a 25W total load. It supports normally on, normally off, or dimmed modes without impairing lamp operation during a power failure.
Who it’s best for: small offices, apartments, or residential basements needing a discreet, low-wattage emergency solution. Why selected: high compatibility with common lamp types and simple integration for limited spaces. Caution: limited to 25W load, so avoid expecting higher brightness during outages.
Fulham FireHorse FHUPS1-UNV-12L-SD Emergency Micro Inverter
Best for versatile voltage environments and dimming control. This 12W emergency micro inverter auto-selects 120/220/260VAC and delivers a sine-wave output. It supports 0–10V dimming and TRIAC dimming, with remote mounting up to 150 ft. It’s suitable for projects requiring flexible electrical configurations and dimming during outages.
Who it’s best for: commercial or institutional installations with mixed fixture types and dimming needs. Why selected: broad compatibility and dimming capabilities enhance post-outage safety lighting control. Caution: longer remote wiring may require careful installation and compliance checks.
Bodine Emerg. Lighting Inverter,25W,120/277VAC
Best for US-based emergency lighting systems with standard 120/277V supply. This Bodine unit is designed for emergency lighting and exit signs, offering a 25W output suitable for many conventional fixtures. It is a straightforward choice for facilities prioritizing a U.S.-made option and simple integration.
Who it’s best for: facilities needing a straightforward, American-made emergency inverter. Why selected: simplicity and compatibility with common emergency lighting layouts. Caution: limited to specific load types; verify fixture compatibility before replacement.
Bodine BSL36 Cold-Pak Emergency LED Driver
Best for extreme cold conditions and LED emergency lighting. The BSL36 is designed for operation in very cold environments and provides robust emergency performance. It is UL listed and supports a wide temperature range from -20°C to 55°C. It is a strong choice where temperature extends beyond typical indoor ranges.
Who it’s best for: facilities in refrigerated spaces, unheated basements, or arctic-like climates. Why selected: reliable cold-weather operation. Caution: not a universal retrofit; check compatibility with existing fixtures and control gear.
Iota I42 A Emergency Lighting Battery Pack
Best for ballast-compatible emergency lighting with higher initial lumens. The I42 A provides an initial 650 lumens in emergency mode and a 90-minute runtime, with temperature and compatibility features enabling end-of-lamp-life considerations. It supports 120/277 VAC dual inputs, expanding fixture options.
Who it’s best for: projects needing substantial emergency brightness and ballast integration. Why selected: strong lumen output and adaptable voltage. Caution: ensure ballast compatibility with existing fixtures to avoid non-operational contingencies.
Iota ETS-20-DR Emergency Transfer Device
Best for auxiliary power support via generator or inverter during outages. The ETS-20-DR provides 120/277V input with LED driver support (8A at 120/277V) for NEMA 410 compliance. It ensures auxiliary power can back switched fixtures during power failures.
Who it’s best for: facilities needing reliable transfer to alternate power sources for switched fixtures. Why selected: explicit design for emergency transfer and compatibility with generator/inverter back-up. Caution: integration complexity may require professional installation.
RAB DRI-25-EMGR-DC 25W Emergency LED Inverter
Best for use with select RAB commercial downlights and to meet UL924 requirements. It provides a 25W output with a rechargeable or direct-in operation model. Recharge time is listed as 36 hours, with a compact footprint suitable for tight ceiling spaces.
Who it’s best for: commercial environments using RAB fixtures that require UL924-compliant emergency power. Why selected: vendor-specific compatibility and compliance focus. Caution: verify fixture compatibility within the RAB line before selecting.
Buying Guide: Key Considerations For Emergency Lighting Inverters
- Load rating and runtime: Match the inverter’s wattage capacity to the connected emergency load and desired runtime (90 minutes is common in many models).
- Voltage compatibility:check input/output voltage ranges (120V, 277V, universal 100–277V, etc.) to fit existing electrical systems.
- Fixture compatibility: Ensure the unit supports your lamp type (LED, fluorescent, incandescent) and whether dimming features are needed.
- Form factor and installation: Consider remote mounting distance, cable runs, and whether a compact unit fits in existing enclosures.
- Regulatory compliance: UL924 or equivalent listings indicate suitability for emergency lighting applications.
- Dimming and control: If post-outage lighting control matters, prefer models with 0–10V or TRIAC dimming support.
- Temperature range: For cold environments, select units rated for low temperatures to prevent performance loss.
- Reliability and maintenance: Look for rugged construction and straightforward replacement parts or modules.
Frequently Asked Questions
- What is an emergency lighting inverter used for?
– It supplies power to emergency lighting fixtures during a power outage, ensuring safety lighting remains active for a set duration. - What wattage is typical for emergency inverters?
– Many units provide 12–25W for standard small to medium lighting loads; larger systems may require higher wattage. - Do these inverters work with all lamp types?
– Most are designed to work with LED, fluorescent, and incandescent fixtures, but always verify fixture compatibility. - Is UL924 a common requirement?
– Yes, UL924 is a common standard for emergency lighting control systems and is often required for commercial applications. - Can dimming be used during a power outage?
– Some models support 0–10V or TRIAC dimming, allowing control of lighting levels even in emergencies. - Should I buy a universal voltage inverter?
