XinTD X3. It's a 3*AA light. Not as bright as a D40A. At stock, throws as far as a D40A. I have both (NW versions), so I can compare. Comparison is also done by eye, rather than raw numbers.
However, the XinTD can be easily modded to throw further. A simple de-dome on an XM-L2 U2 1A will result in a tint shift towards neutral with hints of yellow/green in tint, along with greater throw.
I have a Big Head K8 which has a similar sized reflector to the XinTD X3 and both have 2.8A going to the LED. I modded the Big Head K8 with a de-domed XM-L2 U2 1A, and powered with one cell, it out throws the XinTD X3 and D40A quite easily. Brightness also seems comparable to the D40A when doing a light bounce test in the bedroom. Note that the K8 was powered by an 18650 and the XinTD and D40A with AA's.
