Very interesting. LED's thermal concerns can make it quite complicated.

"With LED lights, the LED is the source of light and the heat generated by the LED is in direct contact the LED light bulb..." LED's are not "light bulbs", they are chips or dies. "The direct contact is a result of how the LEDs have to be attached to the driver circuit..." It has less to do with how the LED's have to connect (not attach) to the driver circuit and more with practical aspects of getting the heat out.

what is wrong with using a simple control loop to control the LED current so the LED is operating at a safe temp? No need for the red LED and measuring lumens, etc. your approach is too complicated.
