Check out the command called ies2rad.

Hi George,
You want to check out the manpage for "ies2rad", which is the Radiance
utility for converting an ies photometry file to a Radiance light source.
There are a bunch of options so read it over carefully, but it works very
well. ies2rad will read in the ies file and create a luminous source based
on the dimensions it finds in the ies file. The output is two files: a
.rad file that describes the luminaire and a .dat file that describes the
distribution. Using replmarks, another utility in Radiance, you can place
"markers" in your model that can be replaced with the luminaires you
create with the ies2rad utility.

Depends how fancy you want to get with it. ies2rad does a basic import, but it takes some additional effort to combine the photometry with luminaire geometry. I'm working on a program which (I hope) will simplify the job, but it is not quite alpha yet.
Ooops! Hit the wrong button & a partial reply went out.

What's your situation? What are you trying to do?

Be especially careful with the units and lamp color look-up, most people
normalize to white as long as there are no different lamp types involved
in a project. It may be a good idea to place some measurement points and
get the illuminance from rtrace to verify everything is fine - IES file
handling is rather messy in my experience.
Cheers, Lars.
My ltview utility is also useful for checking distribution, and that
orientation was translated the way you expected. It wraps your luminaire in
a 4' square box, places your eye looking along the +y and sets -ds .15 -ab 1
to get a decent view of the light. If working in different units, you can
use the -bs option to scale the "box size" so it's reigned in appropriately.
You can download a copy here:

...and there's a short, stupid post on it here:
