Normal ceiling fan is 80W

You can buy dc fan at 30W.

100 hour is 8 unit vs 3 unit
1 unit is around 22 sen/per unit
1 day 12 hour
RM7.02 vs RM2.64
1 month differential is just around RM4.38
u buy a rm200 fan vs rm 400 fan, u need 50 month to save back the differential

Now this is quite informative, thanks. So if we have for fan running 12 hours++ a day, in a month we can save about RM5 x 4 = RM20. In a year RM240. Let's say we use the fan for 10 years, we can save RM2400... I thank that's a pretty good roi no?

yap, best ROI in the best perfect world!!!

in a perfect world, the electronic component will stay in perfect working condition for a perfect optimum 10yrs, it will never go faulty for the next 10 perfect years.... whistling.gif  whistling.gif  whistling.gif

but in reality mostly after 5 yrs above, once goes bad on the control board, they will chg to a new fan again, and again

save 2400??!! more like a marketing gimmick to lure those who always live in a perfect world...!!!

Hmm I don't know about fans nowadays, but the ceiling fan at my parent's house are almost 15 years old already and it's still working perfectly well without us changing/replacing/repairing any single thing. The only thing we need to replace is the remote, which I bought RM10 universal fan remote

see fellow with experience answer above!!!
and I bet your parent's house fan is the old fashion AC+Capacitor type which will run con't for another 15yrs if no major power surge.
