Pair of Eco Tech Radion XR15 Gen 4 - Purchased new and used on my Reef tank

I replaced the Radions with new lighting with the intent to sell them. They are currently set up on the Mobius app. When I checked them prior to listing, one light came on but just flashes in a strobe like manner. The other light does not come on at all. Both power supplies appear to be fine. It appears that they are repairable according to the inter web. 

Comes with original boxes and packaging.
