The history of electric light is well documented, [11] and with the developments in lighting technology the profession of lighting developed alongside it. The development of high-efficiency, low-cost fluorescent lamps led to a reliance on electric light and a uniform blanket approach to lighting, but the energy crisis of the 1970s required more design consideration and reinvigorated the use of ...
The reflection-based daylight redirecting film, stuck to the inside of top part of the windows, is reflecting light sharply up onto the ceiling. This is a suboptimal use of prism lighting. While the ceiling does diffuse the reflected light, it still mostly lights the area nearest the window, where it is superfluous.
Daylighting can cut lighting energy use in some buildings by up to 80%. [6] Toplighting (skylights) works well with sidelighting (windows) to maximize daylighting: toplighting is able to bring light into centralized areas of a building; daylight is available throughout the day from both ambient lighting from the sky and direct exposure to the sun.
