I recently purchased a Neutral White version of the D40A, and thought you might be interested in how it compares to the Cool White version tested here.
First, there has been a change to spring design in the head:
This new sample has a larger and more pronounced spring. It is also perfectly straight. This should presumably help prevent the issues some people have apparently experienced of poor contact or potential shorting (from a bent spring).
As for tint of the new Neutral White, that is hard to describe or compare in pictures. Sunwayman doesn't report the tint bin. I have seen speculation here that it is 3B, which is reasonable (i.e., it is a bit on the green-side of "creamy yellow", and I would personally have guestimated 3B, or maybe a 2C at worse). FYI, see the flashlight wiki site for a tint chart.
In any case, to give you an idea, I have done a series of comparisons using the two best-match white balances that I could find on my camera (i.e., the two that most closely matched what I saw by eye). Note that neither of these is "perfect", but together should give you a pretty good idea of what to expect in a comparison. FYI, I find my Cool White sample to have a very "premium" cool white.
Again, I find my D40A Neutral to be a bit on the green-end of "creamy yellow" - although that may not be captured above, due to white balance differences. And I have no way to predict how that will show up on your graphics card/monitor - those are just the two best white balances on my camera, to my eyes. :shrug:
FYI, I personally prefer a slight rose-tint to my Neutrals (i.e., something more like a 4A/4B). I don't know what my Eagletac G25C2 XM-L Neutral white is, but it is closer to my preferred neutral. Again, here's a couple of the best white balances I could find:
Again, no single white balance will exactly capture the difference you see by eye. But the two examples above should give you a rough idea of how things compare.
UPDATE: I've just tested the output of the D40A Neutral White compared to my earlier Cool White sample. Here are the results from my ceiling bounce and lightbox:
D40A Cool White: 211 ceiling bounce, 940 estimated lightbox lumens
D40A Neutral White: 192 ceiling bounce, 840 estimated lightbox lumens.
That works out to a 11% drop by lightbox lumens, and 9% drop by ceiling bounce. As a result, I'd feel pretty comfortable saying there was a ~10% drop in output on my Neutral version. :wave:
