Ellie from RCM has been kind enough to email back and forth with me. She said that the LED lights should be lasting 3 years. If that's not happening then she said she would help with a replacement. She's also looking into the little 36 printed on the label (I was curious as to the official explanation). Apparently, she's not aware of what it means and contacted her boss for clarification. It'll be hysterical if the DIYer's knew the product better than the company!!
