How many emergency lights do I need? Count the identifiable exits, stairs, turns and risk locations in a commercial building, then use the result alongside the emergency product range and the requirements calculator before the final design is fixed. It is a straightforward way to separate coverage points from the final luminaire schedule.
Count final exits, stairs, route changes, firefighting points, windowless rooms, open areas and high-risk tasks that are already identifiable from the project information. Those points usually become the first items in the emergency lighting schedule.
Product spacing, maintained illuminance, mounting height and actual escape geometry still need a compliant design. Keep the test method coordinated with the project’s lighting controls so the control gear and test arrangement are clear from the outset.
Mounting, exposure, testing and sign type determine which emergency lighting ranges appear after calculation, including where emergency conversion forms part of the normal luminaire schedule or where a sign-only route is enough.
No. It identifies likely coverage points from the information entered. Final quantities and positions still require the actual escape geometry, mounting heights, product photometry and maintained illuminance to be checked.
The schedule may include exit signs, surface or recessed emergency luminaires, bulkheads, twin spots or emergency conversion within selected commercial luminaires. Mounting, environment and testing method determine the relevant range.
Include the building and area types, estimated coverage points, mounting positions, exit-sign quantities, maintained or non-maintained operation, required duration and the preferred testing arrangement.
