Referring to some LEDs as Chinese cheap knock-offs is amusing. Virtually all LEDs are made in China, as are most other electronic components. Being made in China means made in China - nothing else. The LED light I'm using now has made in China, unbranded, Ebay special LEDs, and it works fine. It has been in use about 18 months now.
Is there a link to more pictures? I want to see how the plants are doing I really like the way the lighting looks.
