I'm not an engineer, but looking at those things makes me wonder how efficient the heatsinking actually is. The LEDs in the middle of the array can't take advantage of the blade type symetry because heat has a much, much longer way to travel. Curious how they got around this. Vertical convection though is likely really good, and the cellular nature of the design makes it easy to just add more blades if you want more light. Most current lights have to use horizontal convection for cooling and this is prone to a lot of problems. Radial heat sinks with thick, blunt fins that gradually tape are the most efficient in the thermal models, and this looks like conceptually at least 1/2 of that idea.
This bugged me though:
"While everybody else was creating standard shoeboxes and other conventional designs, we were approached with a revolutionary technology that allowed us to throw out all preconceptions of how urban luminaires should appear,"
Yeah....Ok...I'm sure every City, County and Municipal planner has aethestics at the top of their list. But if you want your corporate parking lot to look like it was terraformed by the Decepticons this product is at the top of your list.
