We are looking for advice on the size and spacing of recessed
LED lighting for our new custom home:

1. Living room: 20 ft by 20 ft with 20 ft high ceiling

2. Family room: 20 ft by 30 ft with 15 ft high ceiling

Could you please suggest, what size, wattage and spacing
shall we use for above rooms?

Thanks much,

Ash & Sonia
