Hello All,
I haven't read all of these posts (there are 56 pages now!), so I apologize in advance if someone has already posted something along these lines.
I do a fair bit of image processing for a living; while I know nothing of what falling meteors look like on digital film, I do know how to process images to show trends, etc. We are fortunate in this case, because we have virtually identical images, one with the 'oddity' and two without.
Below, I shall present images which are the result of OBJECTIVE mathematical operations performed on the set of three images (from the first post in this thread). These mathematical operations are performed on the entire image set, so there is no human hand that's tinkering in the works. Furthermore, anyone with Adobe Photoshop can reproduce most of these results with the 'apply image' feature (and using addition, subtraction, and difference blending modes); advanced image analysis was performed in MATLAB and C++.
First off, here are image enhancements from a basic difference analysis algorithm; this algorithm adds and subtracts the three provided images in such a way as to only show the differences common to the three. You can think of this as a process that uses information from the two 'clean' images (no 'oddity') to construct background information; the background information is then subtracted ina statistical fashion from the image with the 'oddity' to reveal underlying features that are not contained in the clean images.
Here's a low quality result of the entire image field:

and a higher quality result of the region of interest:

The features in the above images represent data that is not common to all three original images; thus, the 'oddity' is substantially enhanced because it is only in one image.
If this seems too abstract for some of you, here's an overlay of the enhancements with the original scene (low and high quality, as before):

I ran some other more esoteric filters on a smaller region of interest around the 'flash', and here's a side-by-side comparison of the results:

Given the general tone of the posts in this thread, I don't feel the need to elaborate on the math involved unless asked; just think of these enhancements as different methods of looking at the data contained in *all three* of the original images.

RESULTS OF ANALYSIS:
As you can see, the alleged 'flash' and 'smoke' halo have been greatly enhanced, in some cases by very basic mathematical processes (again, I want to stress that all math was applied to the *entire* image fields; there was **no** subjective hand-tweaking or localized treatment, a.k.a. 'photoshopping'). We are very fortunate that the 'before' and 'after' images were provided, because this degree of enhancement would not be [objectively] possible with only the one 'oddity' image. (the two extra images were similar enough to reinforce the overall signal-to-noise ratio of the features in question; enhancement was accomplished with no 'a priori' knowledge)
Of particular interest is the shape of the alleged smoke halo. It appears to be nicely symmetric about the tangent of the alleged 'contrail'. This is NOT consistent with shrapnel of an exploding lamp bulb for obvious reasons (explosions are rarely this symmetric), and the impulse, shape, and concavity of the alleged smoke is NOT consistent with an iris lens flare (what happens when you point a camera at a bright light); such lens flares always have original symmetry about the light source (well-known fact) and the alleged smoke halo clearly does not.
Also, I could claim with a moderate confidence level that the epicenter of the flash is not at the point where the lamp would normally project light; rather, it appears to be slightly to the right in these images, which could translate to be upwards of a two or three feet to the right of the lamp (in real space). If the flash was caused by a lamp explosion, I would expect the flash to be fairly centered on the lamp; also, I would expect extensive charring & damage to be visible on the lamp upon inspection, and not much damage was noted (? unclear about this from previous posts).
Given these results, I believe the 'flying insect' theory can be readily dismissed for several reasons:
-the odds of getting such a symmetric portrait of an insect amid flight are astoundingly small
-the alleged smoke halo was very well resolved by the camera (i.e. its edges were quite sharp in comparison to the SNR of the entire image field); this is not consistent with a flying insect traversing the image, which was taken with a 1/20th second exposure; experienced photographers would unanimously agree that 1/20 exposures aren't nearly short enough to resolve the major features or wing movement of a flying insect in motion
-the aforementioned focal issues, which I believe to be accurately stated...
Given the span of the 'smoke' halo in relation to surrounding features, I have conservatively estimated the halo to be 30 feet long (assuming it is roughly in the plane of the lamp). Given this, I believe that any 'lamp electrical discharge' theories are not valid, because such a streamer would require many millions of volts. Also, if the halo was a result of glowing ambers flying away from an electrical discharge of ~120/240V (or whatever the Aussies use in their lamps), then the symmetry of the halo would not be observed.

BOTTOM LINE
It is my informed opinion that the 'oddity' and associated 'contrail' **cannot** be attributed to an exploding lamp, a lense flare, an electrical discharge from the lamp (including the rather conspiratorial theories of directed energy weapons), or a flying insect.
I cannot determine if the 'oddity' is consistent with lighting or other environmental factors without speculation, because the observed symmetry of the 'smoke halo' would generally rule out lightning as a cause (improbabilistic).
Using an array of proprietary, in-house filters, I cannot rule out digital tampering of the image; there are some suspicious noise distributions that could be associated with either tampering or a poor CCD chip in the camera. Given the several visible dead pixels in all three images (one is readily visible in the water of the foreground), the abundance of inhomogenous color noise associated with such entry-level digital SLR CCD's, and the alleged trustworthiness of the photographer, I believe it is entirely reasonable that the camera would be the culprit here... not a human hand. But mathematically, I cannot make this assertion.
Given the scenery in all three images, I cannot find any endogenous content that could cause both the flash and the contrail simultaneously (w/i the 1/20th second of the exposure). If any such content exists, it is either unresolvable or escaping my thorough search.
It is my humble opinion that the contrail, flash, and smoke halo are consistent with a falling object of substantial mass and velocity. My reasoning is:
-the contrail is a confined, darkened region of marked linearity; this is consistent with a trail of partially-combusted debris from a very hot falling object
-the flash is not centered on the lamp, which is consistent with the falling object striking the lamp housing at some point and undergoing fragmentation; the fragmentation would substantially increase the oxidative processes at work for a brief instant after the strike (as the reactive surface area is increased along fracture surfaces by several orders of magnitude), creating a 'flash' originating at a very short distance from the strike
-after fragmentation, oxidation would rapidly extinguish as both the temperature and velocity of the falling object fragments rapidly decrease; this could create smoke trails consistent with the 'smoke halo'
-regarding the symmetry of the smoke halo, I believe it to be consistent with the well-established annular shape of ballistic fragmentation; this shape has been well-observed in the field of forensic ballistics, among others, where a ballistic object undergoes unconstrained disintegration upon a hard impact (usually done in ballistics gel with fragmentation rounds)
-assuming that the alleged smoke halo is indeed smoke, the wind in the scene (I've tracked it moving back and to the left, using the surface of the water in the foreground) would very quickly dissolve such a weak smoke concentration and rapidly disrupt any symmetry (in the timescale of the span between exposures); given this and the SNR of the images, I believe it is entirely reasonable that the events of the 'oddity' occurred entirely in the duration of time of the one exposure; if the oddity were indeed a falling object which traversed the contrail to strike the lamp, even the most conservative of relative distance measurements would clock the object's speed at well over the speed of sound, again consistent with a ballistic falling object
Nevertheless, I am still troubled by the contrail (darkened line). Something is strange about its variable density and SNR... I'm still thinking this one over. However, I do not believe that it is a ray shadow from an occluded light source; such shadows are only observed when the relative humidity is high enough for sufficient scattering of light in the air. Given the clarity of the foreground, this does not appear to be the case.

... this turned out to be a massive post; I apologize in retrospect, and as well for any typos. If anyone has read it all up to this point, I'd appreciate your feedback. My goal here was to uncover new evidence via the image enhancements... I'd enjoy hearing what the APOD crowd thinks about these.
I'd also be curious to hear the evidence supporting the rapid dismissal of the falling meteorite theory.
