I picked up two used Prime 16's about 7 months ago. A few months back I started to notice that one light gives off a more purple tone during ramp up/down. I confirmed by placing paper underneath. I understand that this may be something AI would help with if I purchased them under warranty. But I'm looking for replacement LED assemblies for both so I can just be done with it. I checked the AI website and they only offer the lenses and mine are fine. Are the LED's available anywhere?
