Buy a regular light and fit it with a 12 volt edison-base (standard base) bulb. These are available in various wattages at marine supply stores.

Even better, fit a 12 volt DC compact fluorescent. These are available from several renewable energy suppliers.

Did you ever find a 12v post light? I, too, am looking for an affordable low voltage post light -- not the deck style light, but a larger decorative style for brick columns in our front yard. The website you referenced appears to have been sold to another company -- the stock is not the same as before. Any info would be greatly appreciated.

Or, were you able to re-fit a regular light?

Thanks.
