We measured light levels (in footcandles) inside a 8' x 9' x 53' trailer with a wooden floor and ceiling and white fiberglass walls.
A matrix of nine measurements were taken at five work plains inside the trailer. Averages were figured along the center work
plane of the trailer.
These charts measure the overall quality of truck trailer illumination from a selection of light sources. Many other factors such
as: cost of energy, safety, availability of fixtures, cost of labor and replacement lamps should figure into your final decision.
