Threshold meanings

Hi,

What is the reason behind the 300 lux-3000 lux threshold?  Does above 3000 lux refer to areas that glare occurs?  What are the references behind these thresholds?

 

Regards,

Nil

Read this, IES LM 83-12. It is the publication of the work done by the Daylighting Committee that established those thresholds and why. There is a lot in there to type here as to why and many the references and research i cannot remember off hand.
