What kind of code is it?

I need to write a short answer for each question for exam
STUDY GUIDE:
– 3 ways lighting can interact with a surface
– What does the ADA (Americans with Disabilities Act) says about wall sconces
– UL, and what NRTL stands for. Different UL Listing Types.
– Lamp Efficacy vs Fixture Efficiency
– Brightness vs Intensity
– Beam Angle vs Field Angle
– What is the NEC for? What kind of code is it?
– What are energy codes for and what do they limit specifically for us?
– Parts of the eye, with particular focus on Rods and Cones, photopic vs scotopic vision.
– The primary colors of light
– What does a Spectral Power Distribution Chart show us?
– The electromagnetic Spectrum and the range of visible light within it
– Halo/silhouette vs back-light
– Wash vs Graze
– Footcandle requirements for Food Prep and Emergency Egress
– IP ratings
– High contrast vs low contrast spaces, and how this relates to directional vs diffuse lighting
– The 2-5 rule
– What does LED “binning” refer to?
– Weight above which we need a structural engineer
– What is a Macadam Ellipse?
– What do the letters AHJ stand for?
– What is the difference between Codes and Standards?
– Color Temperature
o Units
o Low/high warm/cool
o How it connects to the Black Body Locus
o Where do we see the Black Body Locus?
o General usage of warm and cool color temps
– The Inverse Square Law
o Formula
o Practice using it!
2
– The Lumen Method
o What is it used for?
o What must generally be true about your lighting fixture layout in order for it to be useful
and valid?
– Lighting units
o Lumens (Total Lumens, Total Luminous Flux)
o Footcandles (Lux in the rest of the world)
o Candela (Normally found as Center Beam Candlepower or Maximum Beam Candlepower)
o Watts
– CRI
o What does it stand for
o What lighting types are 100 (perfect) CRI sources
o Even though 90 CRI is good, why is it maybe not good enough?
