I started the move to Chinese panels and got the snot kicked out of me on this forum early on. Time has passed and more people have taken the plung, so yes, there is more support using these panels. Tautronics is just a importer that sells on EBay and Amazon. Their panels seem to work fine. I got mine directly from the factory in China as I import things in my business sometimes. They all look identical even though built by several plants. When I distributed them, I also got spare parts so I could fix them as well. But the Internet price was so cheap, I abandoned the resale of these to build my own light. Besides the forum moderators gave me heck every time I mentioned I sold them. I sold panels from 60 watts to 400 watts.
The panels you showed use the same emitters powered at 3 watts each. The first of these used 120 emitters powered at only 1 watt each, then they went with 2 watts, now at 3 watts. Same parts generally. If the factory has done a good job of heat sinking these parts, all will be well. I have 840 watts of LEDs split between the display tank and the algae turf scrubber system. Running for 4 years, I have had one panel fail. 1/3 of the panel went dark. It was a early panel, so the LED
was not replaceable. Since then, the panels have been upgraded (some of it at my insistence) and should not have this issue anymore. My tank is shown in pictures and videos that LED
can and will grow about any kind of coral you want.
