Heavenbright LED Panels, breaking down the specs.

What is your problem with HB ? I can understand the anger against AP but his panel ? Is somebody get hurt by the device, is the panel fails on a regular basis, it can't grow weed at all ? If you don't own the panel, you don't know what the panel is really worth. What are you saying at the end ?

For the record, i do not own any commercial panel beside Hans panel.

Peace

1.21- so where do we draw the line on speculation? If nobody has a par meter for the HB and a watt meter to calculate efficiency what can we really discuss here? Other than opinions on the creator or opinions on the design. Oh wait.. If you can read a data sheet apparently you know exactly how the the "luminaire" performs...

Well anyone interested in the efficiency of his systems are welcome to comb through this thread. All the relevent info should be on the first 2 pages.

That being said, how many times are we going to have these dog pile threads on AP and the HB panels? Either buy his products or move on.
