have been pondering something similar. I went with a £30 hygger unit off amazon for my 45cm wide cube. It has fairly basic dimming and timing functions. I've considered adding a second, to give a little more light towards the front of the tank, with the option of running both of them at a lower level or on different timer settings. In retrospect, have wondered if paying more for a light with better control, but in general am pleased with the hygger, for the money. They've now launched a version with much better controls, the 957 which looks great value compared with the big name brands, but seems at the mo to be only available in the US. There are reviews on several US youtube channels, but this one was what I watched.
I'd say, if you do add a second light, there's no obligation to use the same unit as your existing one if you find something, say, at a lower wattage, or with better controls.
