Simple answer: You always get what you pay for!
This is not just true with Fancy Ceiling Fans but for any of your home decor products. In India, ceiling fans can vary in quality. Most of them are cheap, with little durability & most people throw them away after a few years. This causes a lot of carbon footprint as there’s a wastage mentality.
Silent AC motor Fans typically use less energy than the 5* rated ones, save atleast 10% when using the reverse fn, and can save up to 65% by using green tech ceiling fans. The best way is to choose biggest fan you can fit into the room, leaving clearances, and run it on the lowest speed that keeps you comfortable.
Also light efficiency is important, that’s why Luxaire has a lot of Decorative Fans with LED Light that is energy efficient & Ceiling Fans with mood light using halogen where soft lighting is important eg. Entertainment room or small kids rooms who don’t like it dark.
