Tubelights are becoming ever more popular. The last player to join the game is IWATA (whom we remember for their excellent mini panel). Actually, the mini panel was so good and ubiquitous that “IWATA panel” became a generic name for those mini bi-color lights. It seems that that panel was retired, but we were thrilled to learn that IWATA is now making tube-style lights. They sent us two of their new light panels, the 32 cm Master-R light and the 23 cm Master-S light. TL;DR – we were impressed.
