Steve and others:
I chose the unit I noted because it has a toroidal transformer which likely
makes it a switching unit and, according to the description, it will maintain a
constant output regardless of input voltage. Also it has nice screw terminals.

Rich,
On a second look I realized that the devices I ordered will not work for
you since the output voltage cannot be adjusted
lower than the input.
This unit might suit your application. It is a purpose built constant current
LED driver from the same guy, and even less
expensive.

Rich,
I ordered 4 similar devices from this guy a couple of days ago. The price
is a bit better directly from China. My intention
is to be able to run 24 volt equipment.

For those who may recall my little LED cabin lighting project (Fred for one), I
noticed that there is some light level flutter
when my Espar heater or refrigeration is running, an effect that is not noticed
on incandescent lights. I am also concerned about
the long term negative effect of high voltage levels during battery charging.
The only practical solution is to install a voltage
regulator in the lighting circuits.
After a day of unsuccessful local research, I stumbled on the URL below and
have ordered a couple to try out. The source dx.com is
an interesting one you may wish to explore a bit.
