Back in August I bought this bracket arm
<http://www.amazon.com/dp/B00K7146S4/ref=pe_385040_121528360_TE_dp_1> to
be used with two of these LED lights here
<http://www.amazon.com/dp/B0098G9LHU/ref=pe_385040_121528360_TE_dp_2>
At the time there was a question of whether the lights would rotate. As
Moose suggested they should rotate by loosening the attaching screws
under the cold shoes. However, by design, they don't actually rotate
since the square base of the cold shoe rests inside a shallow channel
that is the same width as the base of the cold shoe. That channel
prevents rotation in other than 90 degree increments which is
essentially useless.
But that channel can be easily defeated by putting a 1/4" washer inside
the channel between the channel and cold shoe. The channel is approx.
20mm wide and about 1.5mm deep. A standard 1/4" washer has a clearance
hole for a 1/4" screw (approx 0.3" diameter or 7.6mm) a diameter of 3/4"
(19mm) and a thickness of about 1/16" (slightly more than 1.5mm). The
washer easily fits inside the channel and raises the square base of the
cold foot slightly higher than the depth of the channel and allows the
cold foot to rotate. None of these dimensions are very critical. I'm
sure there must be a similar size metric washer that will suffice. You
could also easily make your own from a piece of plastic or similar
material 1.5mm or thicker. It could also be 19mm square. It doesn't
have to be round. It's only a spacer and has no need of sliding or
rotating within the channel.
I haven't actually tried to use this contraption yet. The lights are
fairly bright. If you live in the US and have a "Harbor Freight" store
around you can see that the LED lights are very similar to this flash
light sold by Harbor Freight.

This light has 3 bulbs on the end and 24 bulbs in a 6x4 array on the
side. The Neewer light appears to use the same bulbs and has 36 bulbs
in a 6x6 array. The Neewer lights are also dimmable which should allow
the use of a "main and fill light" to better control shadows.
