I begin with this last Saturday because the "senior meet" was hosted at our Tennis court. It says that the meet went from 10 A.M. - 2 P.M.

It can be seen that the outside light affected the lighting levels. At its peak, it reaches 500lux at around 12:30 P.M. We can see that the inside light was turned on from around 8-9 P.M. with levels that reach 200lux.

We can see that the energy levels correspond with the previous graph. Although it is interesting to see that each bulb emits different amounts of energy, this may be contributed to the life of the bulb (i.e. the newer bulb will have the higher amount of energy uptake)
