How to Select a High Efficiency Emergency LED Driver

The emergency LED driver provides regulated backup power to light fixtures during a power outage.high efficiency emergency led driver These drivers monitor the power line for disruptions and, when they detect a loss of AC input, switch to battery power. They supply enough energy to illuminate the fixture for at least 90 minutes and comply with National Fire Protection Association (NFPA) life safety code requirements.

The best LED emergency drivers are designed to seamlessly integrate into light fixtures and operate with the same brightness as a regular power source.high efficiency emergency led driver They are available in a wide range of mounting options, including wall-mounted and ceiling-mounted test switches, as well as those integrated into the fixture itself. Most drivers are also UL-listed to comply with the NFPA 924 Standard for Emergency Lighting and Power Equipment.

When commercial lighting was dominated by fluorescent technologies, emergency lumen performance was dictated by the fixed electrical characteristics of the ballasts and bulbs they powered. In contrast, solid state light sources do not have any such constraints. As a result, light output from an LED emergency system is dictated by the power requirements of the fixture itself, along with its ambient temperature and dimming capabilities. For that reason, it is important to select an emergency driver with a wattage rating compatible with the fixture’s power rating, whether you are retrofitting fluorescent troffers or wall sconces in the field to LED or designing new LED fixtures from the start.

LED emergency drivers are available in a variety of power ratings to meet the needs of different light fixtures and applications. The most common ratings are 1-9W, 10-20W, and 21-30W. 1-9W drivers are ideal for smaller fixtures, such as downlights and exit signs. 10-20W drivers are suitable for most commercial fixtures, including recessed and troffer lights. 21-30W drivers provide a good balance of power efficiency and visibility in large facilities, such as warehouses and manufacturing spaces.

LED emergency drivers are typically equipped with manual test switches that can be easily accessed and used by facility staff. Wall-mounted switches are commonly found in stairwells and other areas with low access, while integrated tests buttons are popular in high-ceilinged spaces like industrial lighting fixtures and warehouses. Additionally, many of Bodine’s LED emergency drivers for high bays and other industrial fixtures come with remote-controlled test switches that are easier to use than traditional testers that require climbing a ladder or scissor lift.
