(Summary description)BUG is simply an acronym coined by the Illuminating Engineering Society (IES) and the International Dark Sky Association to better explain how light trespass can be measured. The BUG rating of a luminaire determines how much light trespass that a light fixture produces. The BUG rating replaced the old measuring system known as the “cutoff system” around 2005 and is more comprehensive, taking Backlight, Uplight, and Glare into account (the B, U, and G, of BUG).

Let LONGSUN LED give you a quick guide to NEMA vs IP ratings.
IP – the International Protection Mark (IEC 529)/Ingress Protection system – is more commonly used in Europe. NEMA (National Electrical Manufacturers Association) ratings are for the United States, although IP ratings are gaining ground there too.
Tests are different for the two systems but it is possible to make broad comparisons:
