I got the diamond shoplight t8 2 tube fixtures from Home Depot for $32 or so. Is the light more specular because of the shiny reflector? perhaps I should get a white reflector? What do you think?
At 30$, why don't you get one, try it out and show us? After all this is a quite exotic solution we're talking here.
Though i never really get what "specular" is supposed to mean in photographic terms. In german we speak of hard and soft, so, if you shoot a product, say something with leather, i'd use silver to accentuate the surface / structure, while white will make the surface appear more even -> softer, wich would be unwanted in this case.
The same goes for rim and hairlight, wich is why having both is a good idea anyways.
I'd probably go for silver, because you can easily soften the light with transparent paper for example, but this won't work the other way around. Then again honestly, i have no idea of how visible the difference between white and silver will be when using fluorescent light-tubes, and or if it makes a difference if one shoots digital or analog.
If i look at portraits by David Bailey, who uses a single KinoFlo, i think "wow", but find Hurleys work and others current stuff rather "mushy" or "foggy".
And in general about shoplights vs gintasrs fantastic DIY-job ...
If you don't plan on lugging the lights around and only use them in your studio, the shoplights are much easier to modify. Then again, those edges and corners look verry verry sharp. If they fall down or someones bumps his or hers head things could go really ugly ...
