Just read that there is this new UFO looking LED lights for the nano and pico tanks up to 1.5 feet. Other than the shimmering effect of LED lights, the most noticeable feature is dimming of its white and blue lights (30 levels) and intensity setting, which allows users to digitally set it from 6,000 to 25,000k and for sunrise and sunset effect. It boasts to include high PAR lighting to grow Acropora corals too. However, at 18W, I have my reservations on its ability to keep sps and suppose it is only suitable for less light demanding corals like lps and softies. But if it's true, it's something worth rejoicing for the pico community. Apparently, it has a small footprint and is easy to mount onto the tanks too. I understand the retail price is around $170 here.
Anyway, the website is shown below for your reference.
