How to read these metrics
editorial- BEE star label
- More stars on a ceiling fan mean higher service value (air delivery per watt) in the BEE test — more comfort per unit of electricity.
- Service value
- BEE metric for airflow efficiency. Use it together with blade span and room size; a high star count on a mismatched fan size may not feel better in your room.
- Rated watts
- Nameplate power from the registry. Lower watts at similar airflow can mean lower running cost, but always match fan size to the room.
Tips to compare within DUKE
editorial- Within DUKE, compare models with the same tank size or duty cycle first — star labels are most meaningful when capacity is similar.
- Higher BEE stars mean better efficiency for the same equipment type; check the per-model credit line for when that row was last synced.
- Use CompareStars compare (pick any two or three) to line up star rating, capacity, and standing loss side by side.
