To determine the required rating in candela for the strobe lights in a room, it's important to understand how visual notification devices like strobe lights need to be configured to ensure that they can effectively alert occupants in an emergency situation.

In this case, for a room measuring 60 feet by 60 feet, the area is 3600 square feet. The typical requirement for strobe lights used for audible notifications is based on the area and its occupancy. According to standards set by the National Fire Protection Association (NFPA) and Underwriters Laboratories (UL), the intensity of the strobe light must be sufficient to ensure it can be seen and is effective in drawing attention. The recommendation is generally that strobe lights be rated at a minimum of 15 to 20 candela for ordinary areas, but more intensity might be required in larger or more complex spaces.

For a space this size, providing 30 candela for each strobe light ensures adequate visibility throughout the room. This value takes into consideration the potential obstructions, glare, and viewing angles that might affect how well the strobe lights are seen by everyone present.
