Certified Professional Photographer (CPP) Practice Exam

What color temperature range do fluorescent lamps generally emit?

1. 4,000-5,000 K

2. 5,000-5,500 K

3. 6,500-8,000 K

4. 9,000-10,000 K

The correct answer is: 4,000-5,000 K

Fluorescent lamps typically emit light with a color temperature that falls within the range of approximately 4,000 to 5,000 Kelvin. This range is often described as a cool white light, which can vary slightly depending on the specific type of fluorescent bulb and its phosphor coating. The color temperature is an important aspect to consider when working with lighting in photography, as it influences the mood and tone of the captured image. Understanding this range allows photographers to make informed decisions about how to balance artificial lighting with natural light to achieve the desired effects and colors in their work. For instance, if mixed with warmer light sources, fluorescent light may create a color cast that can be undesirable without proper correction in post-processing or while setting up the shoot.
