There are actually several iterations of the Q-tron: regular, +, mini, micro, and micro +. There are no white "original size" Q-trons
AFAIK, so it was probably just camera flash.
I don't have the specs handy, but if you search on "EHX dimensions" using the Google Talkbass search, it should turn up a thread we had on that very subject. Also, for discussion comparing the various Q-trons, search on "qtron" without the hyphen, as well as the words "mini" and "micro".
The old original ones are the size of a chrome Q'uran.
