In my brief search through the links you extremely fine OverGrow folks provided me I did see that some of the systems included glasses. Understand, I have been aware of the experimentation with LEDs in the early stages, but I have not delved into it deeply or even followed the advances in the field knowing that great advances had been made. I wasn’t aware there was an entire industry devoted to LED glasses until I just did a search for “Method Sevens”. Which, btw, LED glasses is not even it the first few DuckDuckGo results 
Thanks again, @PadawanWarrior
