What Should You Consider When Choosing an LED Emergency Exit Sign Light Blade?

When choosing an LED emergency exit sign light blade for a UK building, consider viewing distance, sign visibility, mounting position, maintained or non-maintained operation, emergency duration and power supply. Check that the product is suitable for the intended escape route and meets the applicable emergency lighting and signage requirements.

What Is the Difference Between Maintained and Non-Maintained Exit Sign Blades?

A maintained LED emergency exit sign blade remains illuminated during normal operation and continues operating during a mains power failure using its emergency supply. A non-maintained model generally illuminates when the normal lighting supply fails. The appropriate type depends on the building's emergency lighting design.

How Do You Choose the Correct Viewing Distance for an Exit Sign Blade?

Choose a sign blade with a manufacturer-specified viewing distance suitable for the distance from which occupants need to identify the exit. Consider corridor length, ceiling height, obstructions and viewing angles. The sign must remain clearly visible along the escape route and comply with applicable UK requirements.
