I guess I'm confused... is a Smat Farm or Noopsyche still considered a black box light? Because they have just as good if not better spread than most high end lights on the market... no disco ball, plenty of shimmer, correct spectrum and plenty of PAR, etc... Inexpensive chinese lights have improved a lot in recent years.
At this point, I guess I consider a black box a light that only has 2 channels; blue and white, and only turns ON/OFF. But that isn't all that is available to us now... Now there are better options than the old black boxes.
Today you can get inexpensive lights with much better lenses, that put out great spread, 6 channels, ramping, moon lighting, plenty of PAR, etc... that I don't really consider black boxes anymore. They are much closer to the high end lights than the black boxes of a few years ago, other than their low prices.
I started out with Viparspectra lights, which I consider a black box, and Viparspectra is probably the best of the black boxes as far as those go. I recently replaced them with Smat Farm lights, which I've found to be a big improvement all around. The Viparspectra's grew coral just fine, but I like the Smat Farm lights much better visually, and they allow more control with ramping and their 6 channels. I did go with
@telegraham's recommendation and also added a 470nm LED bar from Aliexpress to my setup too, for only $40. I have the LED bar on a smart strip programmed to only run during my peak lighting hours each day, since it doesn't dim.
