That's unfortunate, but seeing as they were costly it would likely be an idea to try & find out what the problem is. Each stick features two banks of 3 watt LEDs, correct? Are they dimmable. In all likelihood it's a driver/power supply problem. Could also be one LED gone open circuit & taking out the remainder, depending on how they're hooked up to the driver. I'm guessing each bank of six LEDs has one driver. Since it's out of warranty, no harm in opening these puppys up to have a look see. Could be relatively simple, even cheap fix. It would be a shame to let these things start gathering dust.
