There is no damage from that, an internal temperature sensor prevents the lamp head from overheating. If you have an activity like cave photography in Indonesia, where it is warm and you have little or no movement, you can improve cooling using the add-on heatsink.
This is a precision CNC machined part which fits on the back side of the caving head. You can order the lamp head with this option or do the upgrade yourself - if you have a newer lamp head with the four mounting threads.
