running the leds at 13.3 to 14 volts which is more then 10% above the leds rating.
Your right. From our experience it's the voltage that kills the LEDs first. A lot of LED's are not regulated. When you buy them look to see what the voltage range is. We have had good luck with LED's that are regulated for voltages between 11-15 VDC or 10-30 VDC. Dr LED and GBL LED's sell regulated lights and you'll also find them on eBay.
