Catalogue listing — not a hands-on review
We have not tested this unit. The specifications below are parsed from the manufacturer's own listing, the features are their wording, and the score is calculated from those specifications rather than assigned by an editor. For models we have examined in depth, see our ranked ceiling fans guides.
About this model
The RR Signature Dhoom BLDC is a 1200 mm BLDC ceiling fan selling for ₹3,119 on Amazon.in (MRP ₹4,390, so 29% off on the day we checked). That is close to the ₹3,699 a typical BLDC ceiling fan costs in this catalogue.
Power draw is listed as 35 W. Running 12 hours a day through a 210-day summer, that comes to about ₹706 a year at ₹8 a unit, against roughly ₹1,512 for a 75 W induction fan.
Where these figures come from: the Amazon.in listing for this fan (ASIN B09X2TPSG5), read on 12 October 2026. We have not tested it ourselves, and Amazon prices move daily, so check the live price before you buy.
Manufacturer's stated features
- Rated at 35 W, roughly ₹706 a year to run at 12 hours a day

Worth noting
- Air delivery (CMM) is not on the listing, which is the one number that compares fans fairly
- No remote in the box, so speed control is at the wall
- No BEE star rating on the listing — check the label on the box
When this is not a good choice
Every condition below is derived from this product's published specifications and from how it compares with the ceiling fans we track — so you can check each one against your own room, supply or budget rather than take our word for it.
You live outside a metro or a major service town
RR Signature's service network is rated good rather than excellent. Spare parts and callout times decide how a ceiling fan holds up over the years, so check service for your pin code before you buy.
