BLDC vs induction: the decision that matters most
A conventional induction-motor fan draws 70–80 W at full speed. A BLDC (brushless DC) fan like the Atomberg Renesa 1200 mm does the same job at around 28–35 W. For a fan that runs 12–15 hours a day — normal in most Indian homes for eight months a year — that's roughly ₹1,000–1,500 saved per fan every year at typical tariffs. A BLDC fan usually pays back its price premium in two to three summers.
Two more BLDC advantages people underrate:
- Inverter friendliness. Low wattage means your battery backup runs fans far longer during power cuts.
- True speed control. The remote gives you precise speeds instead of the humming resistance regulator.
Induction fans still make sense where budget rules, or for rarely-used rooms — a well-built one like the Bajaj ceiling fan will run for a decade with zero fuss.
Sweep size: match the fan to the room
| Room size | Sweep |
|---|---|
| Up to 8×10 ft (bathroom, small kitchen) | 900 mm |
| 10×10 to 12×12 ft (bedrooms) | 1200 mm |
| Larger than 12×14 ft | 1400 mm, or two fans |
1200 mm is the Indian standard for a reason — it fits almost every bedroom. Mounting height matters too: blades should sit about 8–9 ft from the floor and at least 1 ft below the ceiling.
Smart controls
If you want voice and app control, the Atomberg Renesa Smart+ adds Alexa/Google support over the standard Renesa for a small premium — handy for scheduling ("switch off at 6 am") and for homes already running smart switches.

Keep it running like new
Wipe blades monthly (dust cuts air delivery noticeably), and once a year check the canopy screws and the condition of the mounting hook. BLDC fans need no oiling or capacitor changes — that's the point.
