If your ceiling to floor height is approx. 8- 9' , and there is sufficient light from the windows, we suggest 5 w for ambience light, 10 w for general light and 15w for task light. Living room should be a combination of yellow and natural light. if it will be used as work area for study , then white light should be included. Generally school projects are made on dining table so white light should be used along with yellow. Kitchen task light should be white. Passage and bedroom could be yellow. Ambient light is generally warm white and yellow. For watching TV, indirect and ambient light is advisable.

Without false ceiling you can use a good quality Silent decorative fan with LED directly - either as 3 lamps below or a single lamp shade. Select fan size & light as per the room area. Also using one or more big colorful pendant lamps (suiting your interiors) can light up the mood!
