The maximum power for an internally illuminated exit sign is indeed set at 5 watts per side. This specification is established as part of safety regulations aimed at ensuring that exit signs are adequately illuminated without consuming excessive power.

The rationale behind this limit is to maintain visibility in emergency situations while also promoting energy efficiency. An exit sign that uses no more than 5 watts is effective enough to clearly convey the exit route in a darkened environment, thus reducing the risk of confusion during evacuations.

This regulation is crucial for compliance with safety standards, as it balances the need for clear exit visibility with the goal of minimizing power consumption and supporting sustainability.
