An optical data communication method with tracking lumen generation and payment for lumen generation from at least one LED light fixture used by a customer, the method comprising: paying to a provider of at least one LED light fixture a predetermined monetary amount as compensation for photons generated by the at least one LED light fixture for a period of time; providing at least one LED light fixture, generating photons of light for a period of time, said photons of light comprising information or data; using a first meter to measure the electricity entering the at least one LED light fixture over a period of time and storing the measured amount of electricity entering the at least one LED light fixture over the period of time in memory on at least one processor; measuring the photons of light exiting the at least one LED light fixture over the period of time with a second meter and storing in said memory the measured photons of light exiting the at least one LED light fixture over the period of time on the at least one processor; automatically comparing at the at least one processor the measured amount of photons of light at each of the at least one LED light fixture for the period of time to data representative of a desired lumen emission level, wherein the at least one processor automatically adjusts the electricity to be provided to each of the at least one LED light fixture to achieve the desired lumen emission level; storing in said memory the adjusted electricity provided to each of the at least one LED light fixture for the period of time to achieve the desired lumen emission level; assigning a LED light fixture identifier to the LED light fixture; communicating the measured electricity and the adjusted electricity provided to each of the at least one LED light fixture for the period of time to a computing device for summation and storage according to a communication schedule; determining at the computing device the summed total amount of compensation to be paid to the customer's supplier of electricity for the summed total amount of electricity entering the at least one LED light fixture for the period of time; and wherein the at least one LED light fixture transmits observable light, the observable light including pulsed light embedded communication or data signals, the embedded communication or data signals not being detectable by ordinary observation by an individual; submitting payment from the provider of the at least one LED light fixture to the customer's electricity supplier for the summed total amount of electricity entering the at least one LED light fixture for the period of time. paying to a provider of at least one LED light fixture a predetermined monetary amount as compensation for photons generated by the at least one LED light fixture for a period of time;
