Luminous Efficiency

Part 1 – Luminous Efficiency and Why Its Important!

In this first video – Luminous Efficiency and Why Its Important, I explain what luminous efficiency is and how it answers these questions: Are led grow lights better than HPS?, How much led power do I really need for my grow space?, and Why do some people get good results with leds and other not? It also shows you ( I wire some up and compare them) the difference between good leds and bad leds!
