Hello,
If you replaced 16000k LED pads with the new 15000k pads but still have the older 90 degree lenses, you will need to replace those with the 120 degree reflectors. The 90 degree lenses are not compatible with the 15000k pads.
As far as your second fixture having problems, is it the same problem you experienced with your other Razor? Since you've had this problem twice now, I would like to offer you, as a courtesy, we can send you the LED pads and 120 degree reflectors for $15 per set. I will also include the reflectors for the first fixture free of charge since nobody informed you that you would need to switch those out if you're changing to the 15000k pads.
I would also like to see pictures of the driver board in the second fixture to make sure there is no issue with that before we send replacement parts.
Let me know if this works for you, and rest assured, you should not have any problems like this in the future.
Sincerely,
Lindsey
