Final answer:
For a factory floor, fluorescent bulbs (CFLs) are recommended due to their efficiency and brightness, while halogen bulbs may be suitable for a break room where comfort is crucial. However, LEDs are the most efficient and long-lasting option, despite their higher upfront cost.
Step-by-step explanation:
When choosing between bulb A (incandescent), bulb B (fluorescent), and bulb C (halogen) for factory lighting, it's important to consider the efficiency, cost, longevity, and the specific use case within the factory environment. Fluorescent lights, or more specifically compact fluorescent lights (CFLs), are about four times more efficient than incandescent lights and can be a good choice for the factory floor due to their efficiency and brightness. They have a significantly longer life span compared to incandescent bulbs, which not only reduces replacement costs but also environmental impact.
For the break room, which may require a more relaxed and comfortable ambience, and likely less intensive lighting compared to the factory floor, bulb C (halogen) could be a better option. Halogen bulbs provide a warm light and have better color rendering, making them suitable for areas where comfort is a priority. However, LED lights, not mentioned as an option in the original question but prevalent in modern lighting solutions, are even more efficient than CFLs, and their long-lasting nature makes them an attractive investment despite their higher initial cost.
Considering luminous flux, measured in lumens, is crucial when comparing the brightness of different types of bulbs. Moreover, factors such as initial investment, lifespan, heat emission, and environmental impact (like mercury content in CFLs) should play a role in the decision-making process. Considering these factors will guide you to choose the most appropriate lighting options for a new factory.
