Ecotech Xr30 Gen2. I had to redo the auction. I apologize for the people that was watching this item before. Good news the light does work and is functional. It must have unsync on my programming. I got on my computer and realized it was no longer linked and once I linked it back on the lights work just fine. So after i ordered new lights, I will auction this one off. Since I no longer need them. As you can see in the pictures there are 2 screws missing on the fan. The fan was replaced about 4 months ago. The light will come with the power supply. Also the sides of the light is sticky must be a flaw in the lights since all the ones i have are like that.
