LED Issue

[dcw1sfu]

Hey my Reef Radiance Dm155e LED now only works with the blue and violet channel. Seems the white and color channel died on it. As its going to cost to much to send it back to get fixed what would be a good replacement option for this light. Dont mind a used light and the budget would be around $500. I also run 4 T5 retrofits in the canopy with the current broken LED 2x ATI Blue Plus 1X ATI coral plus and 1X ATI Purple plus.

Lemme know I see a couple used AI Sol and AI Vegas for sale for a decent price as well as a Radion Gen 2 non pro, but i dont know if these are actually even an upgrade to my last light in terms of spectrum and par. Here is a link to my current light with the single channel working.
