luxlover,
If it weren't for the switch on the L1, A2 and now L2, I never would have come up with the McE2S. I have also found in the last couple months when I have built lights planning on incorporating this switch, that I have gone to higher levels of output for the "high" since this is not the only *speed* that the light will be used at. In fact, realistically, with variable output, I think most folks when really using these lights will be using the low level most of the time and the high level will be the occasional "overdrive" so go ahead and set it at a level of overdrive. I am not sure I am explaining my thoughts properly here. /ubbthreads/images/graemlins/icon3.gif
I do seem to now have in my posession a reasonably intact driver from a L2 so I will fire it up on the bench and measure the current to the LED in high mode. As I recall, the KL4 is somewhere in the low to mid 600's (mA). If, as I expect, the L2 is closer to 700 mA, a reduction in run time would be expected and the performance of these L2's as some of the graphs are now showing, will be explained. I am guessing that as the effecacy(sp) of the 5W's improves, the L2 platform will come into its own and be appreciated that much more.
