What is a key requirement for lighting outlets in serviceable attic spaces?

The key requirement for lighting outlets in serviceable attic spaces is that they must be installed at or near the equipment serviced. This requirement ensures that individuals working in the attic have adequate lighting to safely access and maintain equipment, reducing the likelihood of accidents or errors during service activities. Proper placement of lighting also enhances visibility and allows for effective use of space, making it easier for technicians to perform their tasks without the additional risk of injury from working in poorly lit conditions.

The other options do not align with the specific functional and safety needs of an attic workspace. Solar energy may not be feasible or reliable in all conditions, dimmable lighting might not be necessary for the specific tasks in an attic, and a standard height requirement like being five feet off the ground does not address the critical need for location relative to the equipment being serviced. Therefore, positioning lighting near equipment is essential for ensuring safety and efficiency.
