no I am pretty current. LED especially regular emitters (as is typical with red led's) are just not very high power.

even a typical higher power led is around 1watt. your xenon maglight pulls 10-11watts. its just a pretty big difference in power requirements.

and its even worse than that. with the lower requirements comes a smaller voltage drop off so you can use even more of the available power in the batteries.

led's just flat out rock.
