I sent you the sample special order 12v MR16 lamp.  These bulbs were
specially made on a one time basis.  Some of the Lancair builders on this
forum will remember when I provided prototypes of these bulbs around 5 years
ago.  They are made with special filaments and reflectors with a resulting
pencil-like penetrating landing light beam.  Send me a private email and
I'll see that you get your order.
