Abstract
This paper discusses the current problems that lie with using luminous flux meters as a method of data measurement and why there must be a need for a replacement method. The meters are a common product on the market but they are surprising inefficient when in use. Currently, their only useful for finding the luminous flux of an area but it is impossible for the flux of an individual light to be found using the meter. With the presence of LED lights and drivers now it may be possible to find the flux of an individual piece of lighting using a new method. The new method involves the use of a potential correlation between heat, efficiency and lumen output within LED drivers. This journal acknowledges the current situation of lighting, including common lighting information, testing and testing equipment. Then an in-depth look will be provided about the current problems along with the potential solution. The solution will include a look into the theory, initial or possible equations and an experiment to test and prove the theory.
