In this video we continue to learn about lighting by applying the inverse square law to perform calculations. We'll see the effect that increasing the luminous intensity and the distance from the light to surface has on the illuminance or lux level.

This video is designed to help learners who are studying any electrical course and in particular the City and Guilds 2365, 5357 and 8202 as well as the EAL Diploma in Electrical Installation.
