Which of the following is NOT considered a commercial wattage for fluorescent lighting?

In the context of fluorescent lighting, commercial wattages refer to the commonly used power ratings for fluorescent lamps in various applications. The wattages listed, such as 20W, 40W, and 36W, are standard sizes that are widely utilized in commercial settings.

Specifically, 40W fluorescent tubes are particularly common and are typically used in a variety of fixtures for general lighting in offices and similar environments. The 36W option is also representative of energy-efficient fluorescent lights designed to provide similar light output to 40W tubes while using less energy.

On the other hand, 100W is not a standard wattage for fluorescent lighting. It falls outside the typical range for fluorescent lamps, which usually do not exceed that level for standard tube lighting. Instead, 100W is more associated with incandescent bulbs or specialized lighting fixtures but is not relevant to the standard commercial fluorescent lamps used in everyday use. This is the reason why 100W is categorized as NOT a commercial wattage for fluorescent lighting.
