I purchased this as a fun gift for my wife, knowing her love for stars and ceiling lights in the past from other items she has had. So also, her special"Dragon Love" this item was easy to pick and since she just really was pleased upon seeing him was cool because she nicknamed him "STARRY". Well this thing lights up an 8×10 room w/ the many combinations totally covering the ceiling and coming down a few feet on all 4 sides.
