Many BLDC ceiling fans are promoted primarily on the basis of their power consumption. However, actual consumption is influenced by several factors such as fan size, airflow output, and operating speed. A figure that often comes up in marketing is “28W”, raising the question—can a BLDC fan really run on 28 watts or less?

The truth is, there are two possibilities. First, it could be a marketing tactic, where specifications are presented in a way that sounds impressive but doesn’t tell the full story. Second, the fan may indeed consume that little power—but only under specific test conditions, not in typical real-world usage.
