Not non-existent at all. Eneloop D cells exist (in Japan), but Sanyo refuses to sell them stateside; however, there are at least 3 brands of LSD D cells available, and word among flashaholics is that the Tenergy Centuras seem to be the best quality. (They're better than the previously reigning Accuevolution cells, and recent manufacture Accuevos have a marked decrease in performance.)

Unless this flashlight has a voltage regulator (I am doubtful, given the price), the NiMH cells will keep it brighter than equally-sized alkaline would until running down. You can get a feel for AA battery life by looking at the 1A discharge curves on this page: http://www.powerstream.com/AA-tests.htm
Eneloops are 2Ah, not 1.5, and they'll deliver >1.8Ah at these currents, although inefficiencies in the driver may eat that back up.
It surely does have a regulator, because direct-driving an XR-E from 2 D cells will get you a very feeble glow. It's 3-cell lights (especially 3xAAAs) where they often cheap out and go direct-drive or resistor.
Big Ogre Cudgels!

This happened at the precise instant that the original Texas based company was purchased by Amazon (which is based in WA).
Never attribute to malice that which can be adequately explained by stupidity.
