Depending on the tank size and how many you have,I would just sell them and get a budget t5 fixture and save yourself the hassel or something different.
Mint's are nice,but with those diodes,the spectrum of those more than likely isn't right and will probably fall off within a short time.
This is why I always tell people to use quality diodes. They are worth the money. But cyan will help with color rendition,and uv/violet will help with color,health,growth but within a moderate amount and proper spectrum.
