How is the show window lighting calculated per linear foot?

• A. 100VA
• B. 150VA
• C. 200VA
• D. 250VA

Answer: (C)

The calculation of show window lighting per linear foot is based on the intensity required to effectively illuminate the contents and attract attention from passersby. The industry standard for this type of lighting typically recommends a value of 200 volt-amperes (VA) per linear foot. This figure ensures that the visual display is adequately lit, enhancing visibility and appeal, which is crucial for retail environments where showcasing products is essential for drawing in customers.

This standard of 200 VA accounts for the various lighting types that can be used in show windows, including incandescent, fluorescent, and LED fixtures. Each type has different power consumption characteristics, but the specification of 200 VA provides a good balance that meets the lighting needs while also maintaining energy efficiency. Hence, the answer indicating 200 VA is the most appropriate choice for calculating show window lighting per linear foot.
