Following factors to be considered while designing a lighting scheme

1. Design of illumination scheme should be very simple. 2. Area of the working plane. 3. Find out application of working plane 4. Decided lux level on working plane as per application.(Illumination level) 5. Find out total lumens required on working plane. 6. Decide the type and wattage of lamp which is to be used for that particular application 7. Quality of light 8. Assume waste light Factor 9. Assume utilization Factor 10. Assume deprecation Factor 11. The illumination scheme is designed in such a way that there should be fewer glares. 12. The illumination scheme is designed in such a way that there should be minimum shadows. 13. The control of light intensity is possible. 14. Assume the illumination efficiency of those specific lamps which are to be used. 15. Provide safety and prevent accident. 16. Take care to achieve desired energy saving. 17. Choose lamp with higher luminous efficiency, better color, and longer life 18. For any type of illumination scheme the maintenance & repairing should be less. 19. The cost of the designed illumination scheme should be low
