Bit by bit we are working toward larger LED lights but we want to stay with a plastic construction since we have our own molding capacity, as the LED's get more efficient and as we work with plastic composites to find those with more capacity to dissipate heat we get a higher and higher intensity. For now they are limited to smaller tanks as primary lighting, 30 and below, and for supplemental on larger tanks.
We still have a concept for a full function controller, but we go back and forth on this idea always remembering what Norbert Tunze had said, never make such a product. The primary concern is all of your eggs are in one basket, if that one controller fails, you will have a catastrophe. With that said, electronics have improved and more often then not the same catastrophe would have wiped out all individual controllers as well, such as a flood or spill when all controllers are next to each other. I wouldn't say this is imminent but it gets closer with every development cycle.
