Hahaha. There a bit more to it than that but yea. Ok.There is no question in my mind that LEDs will continue to evolve while other technologies remain stagnate thus in 5 years or so LED will completely dominate the market and MH/T5s will start to die. Both T5s and MH have reached the peak of their technology and will not gain additional efficiency and effectiveness. There is no known ceiling to LEDs, ever two years they get much better than before.
Film still has more resolution than digital.
It cheap and convienient. Easily acesable and a tiny bit more eco friendly.
The current cap on led is why you get less par per lumen compared to t5 and metal halide
The biggest advance kessil could do is admit you can use a par meter on it and post thier approximate specs like Everyone else in the industry.
