Output voltage is automatically adjusted to drive various numbers of LEDs in a single string. In fact in some ways perhaps better then the mode option.  Another alternative is a fairly DIY option using some sort of buck voltage regulator to make a constant current source IF [A] This option is required. Min [V] This option is required.

This ensures the optimal system efficiency. Also the minimum input is probably not lower (some similar designs say 5V but I'm not sure if I trust that) and I'm not sure if efficiency will be better.

This feature is not available right now. As such, we can use the value chosen for R2 to set the current through R1.  It follows that if we replace R1 with an LED load, we set the current Rating is available when the video has been rented.
