I live in Toronto Canada and I'm thinking of installing potlights in the L/D of a bungalo with insulater ceiling 23.84 x 25.09 ft. I would like to know the cost per light and the req amount of lights for that area

Unable to speculate what the cost would be, since we do not know labor and material cost in your area.

Cost will depending how many lights are needed. Quantity of lights will depending on how much light is needed and the size of each light.
