Use this
Trigo Calculator
Key in this
Angle B = Downlight beam angle divide by 2 (if beam angle 110, then put 55)
Side a = Fan height from ceiling
You will get "Side b" which is the minimum gap from tip of the blade to the centre of the downlight.
Then you can size your fan.
Probably better to give extra 2-3" gap for "safety".
Great! A good guide line. I am also about to buy a 60" fan. And worry about disco light effect.Trigo Calculator
