What photometry data formats are used in China, India, and Latin America?

I have a list of US and European formats which includes IESNA
LM-63-02, EULUMDAT, and CIBSE TM-14. There's CIE 102-1994, which Ian
Ashdown reports is not used by any lighting manufacturer. But I've no
idea what's done in China or India, or in, say, Brazil or even Mexico.

Anyone know?

As most of the measurement equipment was made in Europe or in the US,
also the files created with this equipment are those ones used in Europe
and the US. That means EULUMDAT or IES mainly.

Both formats are open and they can do what you need. So there is no need
for more standards.

The widely distributed -and in some cases free of charge- software for
doing lighting design can import this open formats. So again there is no
need for another format.

Of course, luminaires can do much more than it is described in the
standard formats. For example luminaires with multiple light outputs,
RGB luminaires (with different spectra for each channel), luminaires
with complex 3D shape and so on. Also marketing data is not included in
the standard photometric files. But these are photometric files and not
luminaire marketing files. If a lighting manufacturer wants to show the
full range of capabilities of luminaires he will choose for example a
DIALux PLugIn instead of a photometric file only. These PlugIns are
electronic catalogues including photometric data. Similar is the
Instabase of AGI32.

By the way: Ian Ashdown, Lighting Analysts and DIAL have published an
addendum to Eulumdat to enable it to transport absolute photometry data
as well. This has not been possible so far. Check the websites for details:
www.dialux.com (click on DIALux and than on useful information)

We are doing business with lighting companies from all over the world.
If you ask for photometric data you either get EULUMDAT or IES files.
Never heard about other standards in use.

Thank you!

Agreed - I'm based in Mexico and we typically receive IES files from
manufacturers, but a few European manufacturers also use Eulumdat. We
work with DIALux, so either works. Their Plugin format (basically the
optics plus richer models and greater subdivision of information with
differing lamps, etc, works ok, but needs to go a few more steps
before it is fully mature. Problem is that it isn't an open format.
