How to Use the Inverse Square Law to Calculate Light Levels

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.

If one only knows the lux of the light where they are at, and the distance to the source, how do you figure out the lux at the source?

Hi Joe. Love the videos - always clearly explained. Suppliers tend to specify lumen values for bulbs. Would you be able to explain how lumens relate to candelas and lux in a future lighting video?

Thanks for the kind comment. I've already got videos in the works for the lumen method so stay tuned! 👍

Thanks Joe, looking forward to calculating lux values at angles other than 90 degrees from the light source

Hello joe Love to see your lesson if I may please I have a question I have a sum and it says like this: a new similar lamp is to be installed on a pole having the same height the same meters away from the existing lamp so that the illumination under each lamp at the pole is 300lux calculate the distance between the two pole to achieve the required illumination can you help please thanks for your great work kind regards anthony I10 meter high 5m_____l______6m

Hi Anthony, I'm not sure I quite get the question, please could you send me a picture of it via social media?

Hey Stuart! How you doing? I can't believe you're still watching my videos, I'd have thought you were way past someone forcing you to do that! Or has lockdown life bored you that much? 😂

Ah, cheers bud. Yeah, I'm good thanks working from home now on various projects, adapting to this strange time. I'm sure it won't be too long before you're all wrapped up with college mate and onto whatever's next.
