Which statement describes a typical reason MBIs are suitable for high bay industrial installations?

• A. Glow greenish white and have good CR
• B. Glow blue and have poor CR
• C. Glow red and have excellent CR
• D. Glow yellow with moderate CR

Answer: (C)

High bay lighting needs to show colors faithfully so workers can read signs, distinguish hazards, and identify objects clearly from a distance. The Color Rendering Index (CR) measures how accurately a light source renders colors compared with natural light. A lamp with excellent CR provides true color perception across the spectrum, which is essential in large industrial spaces where color cues (like warning labels, indicators, and equipment) matter for safety and accuracy. So the statement that describes a red glow with excellent CR aligns with the idea that high color fidelity is the key reason MBIs are suitable for high bay installations. The emphasis is on excellent color rendering, which makes colors appear correctly; the exact glow color is less critical than the ability to render colors well. Choices claiming poor or moderate CR would not support the color distinction needed in these environments.
