Energy loss and efficiency
Thanks Long John for a nice example of simple efficiency. I have been put off wiring too many LEDs and in your example, 11.8 volts will only supply 2.95 v Not enough forward voltage on a low battery? Anyway, Occam's razor suggests that the simplest solution is usually the best one., so I will...- Richard21

Energy loss and efficiency
Having experimented a lot with LEDs for home lighting, Ive concluded that often more energy is lost in stepping down voltage and current than actually lighting the LEDs. Both resistor and constant current circuits have to 'dissipate power' in order not to overdrive the LEDs. Worst case...- Richard21
