Surefire’s various E-series models are getting brighter. They are also getting slightly larger (again), and the last time that happened (going from the old incandescent heads to the LED heads), some subset of Surefire fans maintained a desire for the smaller, older style which lasts even to today despite Xenon bulbs being horribly inefficient. If you happen to be the sort of flashlight nut who will later wish you had bought the older model, the old ones are currently still available at most dealers even as the new ones are rolling in. Amazon has both the older E1L and the newer/larger/brighter E1L available. The new one also has a much higher MSRP, in case the old one wasn’t high enough for you.
