Quick correction, I worked out that roughly 18V is being dropped across the linear regulator. Not 18mA like I said. The combined voltage of the LEDs is so high that very little more has to be dropped across the regulator. That keeps its temperature down. If it did get too hot it would probably self regulate the current down further.
