Clearly, with the 4000 LW started a new line of rugged-appearing lights. The 2000 was widely (and justifiably) praised as an excellent general utility light. Next, they took on the high brightness market niche with the 3xD 4000, competing indirectly with the Trek Expedition (7 LED x 3C), 1400 and 1900 while introducing their rugged look. The 3000 is a direct competitor to the Expedition and the 1400. The next logical step was to retro-convert the 2000 to the new look, thus establishing a three member family of excellent, tough lights.
I would expect the 2100 to equal or slightly surpass the brightness of the 2000. Until LED efficiency markedly improves I am not eager to sacrifice runtime for brightness, especially in the big "survival" type LED lights. So far,the brighter the LED the more voracious its energy appetite and the shorter the runtime. Sure, it's great to have Luxeons and 5 watters, but the real revolution will come in the efficiency sweepstakes. then we can work on super bright LED's that will burn forever on a couple of AA's.
Lambda, Daniel Ramsey and others (please forgive any omitted names) are genuine innovators. Do they have the imagination and technical know how to put their creative energies to work in helping to develop a truly efficient LED? Or are such achievements usually associated with major labs with large resources backed by a corporation, as is Paul Kim with Surefire?
Forgive my off-topic wanderings, but recently the non-LED world sems to be progressing more rapidly in this dirction with the development of HID, Tunsten Lattice,
and other technologies. In addition, as DestructiveLight laments: "not regulated AGAIN?".... Unless regulation really is counterproductive in most instances, why aren't we seeing more of it, at least in higher end lights?
End of rant, stepping off soapbox.
