The size of the heat sinks don't determine the life expectancy of the LEDs, however the heat generated at the junction point does. Despite it's small stature, our fixture is capable of maintaining temperatures below the manufacturer's maximum rated specifications for the LED's in up to a 100deg environment. However we only claim up to 90deg in order to include a margin for safety. This means that so long as your room stays below 90deg your LED's will continue to operate at max capacity.
Further, the LED temperatures are actively monitored by our driver and in the event that the conditions become too hot for the LED's, the Radion will automatically dim the LED's to a safe level (reducing the current), preserving your LED's and alerting you that your light may need attention. In the extreme case it will shut down the LED's and blink red letting you know an error occurred.
Also realize that this test data collected by us was with all LED's at 100% max power, which equates to approximately 10k color temperature. If you run the fixture at cooler temps the red and green will be dimmed slightly and the total heat produced will be less.
