An emergency lighting inverter (or IPS) allows you to turn your standard interior lights into code-compliant emergency egress lighting. Unlike emergency drivers, which must be installed inside each individual fixture, an inverter sits "upstream" on the circuit. When the power goes out, it automatically kicks in, sending 120V or 277V power to a connected load of fixtures. This is the preferred solution for high-end architectural spaces, lobbies, and restaurants where you want to maintain a clean aesthetic without installing ugly "bug eye" units or accessing the internal wiring of expensive designer pendants.

Mini Inverters vs. Central Systems

We offer solutions ranging from single-room support to whole-building power:

  • Mini Inverters: Compact units (typically 125W to 400W) designed to be mounted in a ceiling grid or on a wall. These are perfect for powering a single row of hallway lights or a specific group of recessed cans.
  • Central Inverter Systems: Large, cabinet-style units (1000W+) capable of powering entire circuits or floors. These are ideal for schools, hospitals, and large commercial buildings.
  • Surface & Recessed Mount: Mini inverters are available in T-Grid mount options to hide completely out of sight above the drop ceiling.

Pure Sine Wave Inverters for LED Fixtures

Not all backup power is created equal. Standard battery backups often produce "modified sine wave" power, which can cause flickering or damage to sensitive electronics. Our UL 924 listed inverters utilize Pure Sine Wave technology. This ensures the output electricity matches the clean power from the utility grid, guaranteeing that your LED drivers run smoothly, silently, and without flickering during the entire 90-minute emergency discharge.

Frequently Asked Questions

What is the difference between an inverter and an emergency driver?

An emergency driver is installed inside a specific light fixture and powers only that one fixture. An inverter is installed outside the fixtures (usually on the wall or ceiling) and can power multiple fixtures at once via the existing wiring.

Can I use a standard computer UPS?

No. A computer UPS (Uninterruptible Power Supply) is typically not UL 924 Listed for life safety. It does not meet the strict runtime (90 minutes) or reliability standards required by fire codes for emergency lighting. You must use a specifically rated lighting inverter.

What does "Pure Sine Wave" mean?

"Pure Sine Wave" means the electrical output is smooth and identical to the power you get from a wall outlet. This is critical for LED fixtures. Cheaper "modified sine wave" inverters produce "choppy" power that can cause LEDs to buzz, overheat, or fail to turn on.

How many fixtures can I connect?

This depends on the wattage capacity of the inverter. If you have a 400W inverter, you can connect any combination of lights that adds up to 400 watts (e.g., ten 40W panels). You should always leave a roughly 10% safety margin.

Do the lights stay on all the time?

Inverters can usually handle "Normally On" (always lit), "Normally Off" (only lit during emergency), or "Switched" fixtures. In a "Switched" setup, the inverter includes a bypass relay that forces the lights to turn on at full brightness during an outage, even if the wall switch was turned off.
