[QUOTE="DaveKamp, post: 213356, member: 5122"] Yep, I think your chart here is very thorough, and if not spot on accurate, certainly close enough. As for brightness, yes, the LEDs do a wonderful job of it, as the energy they consume is in a very narrow bandwidth at the design color, as opposed to an incandescent or halogen, which develops large amounts of UV and IR emmission useless to night vision (in normal humans, anyway). The advantage to LEDs on a motorcycle or boat with permanent magnet alternator, is that there's more power available for auxiliary loads and battery charging. The bad part, is that no matter WHAT you do with your loads, a 500w permanent magnet alternator will ALWAYS be generating the greatest amount of output that it can, regardless of demand... no matter what, if your load is only 108 watts, you'll be generating the full 500w, it just means that the remaining 392w will have to be shunted off as heat. That being the case, one of the first things a guy can do to increase his crankshaft horsepower is to find a way DECREASE his PM alternator's mechanical load. The engineers had this figured out... as you spin that rotor faster, eventually, you get to a speed where the inductance of the stator's windings does NOT allow the magnetic field to change fast enough to 'keep up' with the phase angle of the rotor, and as a result, the mechanical load, and commensurate electrical output... drop off radically.
