objective: design and construct a highly utilitarian lighting device
For my Senior Implementation Project, I decided to create a closet light where the beauty of the form results from a sensitive interplay of explicit function, materials, structure, and context.

vision: elegance, function, convenience, and affordability available for all

opportunity in closet lighting: inadequately lit closets, lighting not on the clothes, and current closet lighting solutions are a hassle

current closet lighting options are not adequate (first three lighting options)
user perspective
“I could always use light in the closet!”
“Nothing worse than fumbling around in a dark closet!”
“Hassle installing enough light into current closets on your own.”
“If it worked well, looked good, and was cheap, I’d buy it.”
“I care about how I present myself professionally, but every morning I have to choose my outfit in the dark.”
