Outstanding bang for the buck and very bright light strip. I have some other 3 k lighting and this strip seems appreciably hotter (color wise), i'd guess 4k, even though the box claims 3k (docking 1 star for the hotter temp). I checked it with an iPhone app and it too was saying around 4.1 k, although I have no way of officially confirming the temp. Other than being a bit hotter color wise, I am very pleased with the quality of the kit. Would definitely recommend and buy again if needed. Not sure if the controller mentions it in the manual, but I can confirm that the a reduced brightness or operating mode is saved and restored with the removal and restoration of power, which is a good thing for my application (under cabinet counter lighting)
