What to Look For Before Buying

Selecting an emergency lighting system requires checking safety standards and codes. Reliability is vital because these devices only run during failures. Consider these factors to find the best fit for your space.

Check Verify Compliance Standards

Ensure the product is UL 924 listed to meet safety rules. Check your local building codes for egress lighting requirements. Non-compliant lights can be a liability in commercial settings. Certification is your best guarantee of safety.

Value Assess Battery Runtime

Most commercial standards require at least 90 minutes of backup. Look for nickel-cadmium batteries for long-term reliability. Check if the unit has a test switch for easy maintenance. The battery is the most critical part of the fixture.

Rating Evaluate Light Output

Think about your space when choosing the number of heads. Dual-head fixtures are great for hallways and stairs. I suggest looking for adjustable heads to direct light. High-lumen LEDs work better in large, dark areas.

Verify Confirm Installation Needs

Decide if you need hardwired or plug-in units. Check your building voltage for 120V or 277V compatibility. Verify that the mounting plate fits your junction boxes. Proper installation keeps the unit secure and functional.

Frequently Asked Questions

How often should I test my emergency lights?

Most codes require a monthly functional test. You should also perform an annual 90-minute discharge test. These checks ensure your batteries and LEDs are healthy. Keep a log of these tests for inspections.

Can I use these lights outdoors?

Use them outdoors only if they are rated for damp or wet locations. Most standard lights are for indoor use. Always check the packaging for environmental ratings before you install them.

What happens if the battery fails?

You must replace the battery pack to stay compliant. Many brands offer specific replacement batteries for their units. Never ignore a failed battery indicator light on your fixture.

Are these lights compatible with all voltages?

Many commercial lights are dual-voltage. This means they support both 120V and 277V. Always check the specs before connecting to power. Using the wrong voltage can cause permanent damage.

How long do the LED heads last?

High-quality LED heads last for many years. They rarely need replacement under normal conditions. The battery will likely reach its end of life much sooner than the LEDs.
