Hi Glen
"What makes you think you need to heat sink this light? Surely not the 1.3
amps it's drawing?"
Exactly it's the 1300mA draw!
I didn't purchase yet.
I did just today talk to the Mfg. and he said he recommends it be sunk to
at least 60 square inches of aluminium. He said if it is in airstream it
would probably sink enough, but if you left on in a hangar for 5 to 10
minutes you would damage.
He said he has been working on a design for 3 years, his CNC aluminium
housing works well to extract heat from the LEDs, but ya gotta get the
heat out of the housing.

I am thinking to mount on one of my outrigger fairing, just make at least
the front out of aluminium with a 1/16" polycarbinate cover. As far as I
am concerned, aluminium and fiberglass is a composite!

Yikes,
Thanks Ron, it sounds like mounting it in the cowling inlet would be one
way to go. With the Legacy you can't have little things sticking out or
people talk funny about your airplane  You could probably mount it in
the cowl if you did a scat tube into the housing and protected the tube
mount on cowling itself.
I'll have to come up with a creative way to protect the mounting base
such that excess heat does not pass through the housing mount to the
fiberglass. I normally use the Click-Bond stud mounts for stuff like
this. If I can find a way to insulate the stud from the housing mount,
that should do it. Somewhere in industry there should exist insulated
mounts for stuff like this.
