Supplemental light or new lighting?

[Nano]

Any suggestions guys? I looked at aqua illumination and am not seeing the par values or spread of them for the price point and after watching some videos of the par being tested in tanks I'm unimpressed to say the least. I do like the idea of the wifi control that's pretty slick but I feel I can do better as the led market seems to have expanded a lot in the last 4-5 years. Radions are definitely nice units but I'm not looking for something quite that expensive. I'd like to stay under $350 for my size tank or less. Which I feel should be plenty for and 18inch cube
