cheap led build

I find this in Amazon, I start to use two of them in my tank, how do you feel about this LED?

Prototype LED/T5 If your like me LED’s now days are way to expensive. What I wanted was to get T5 fixture with 2 radeons but instead I built my own. Excuse poor cable management as is only a prototype. Parts 2 48” T5 retrofit 7$ each without ballast 1 dual t5 ballast 60$ 4 50w Blue 455nm...
