Quick answer: Probably either 2450 K or 2500 K.

Long answer: Read on.

Googling on

Philips 13713X filetype:pdf

leads to this page, which appears to be part of a Philips catalog, but
is hosted on a third-party site:

http://prolight.info/pdf_specs/irk-philips-industrial.pdf

Page 3 of that PDF has the following lines in the table for this lamp:

Type Base CCT K Ordering number
13713X 220-250V 1000W X 2450 9238 515 43900
13713X/98 220-250V 1000W X 2450 9238 960 44500

That PDF doesn't otherwise explain what the "/98" on the end of the
type number means.

The same search also leads to part of a different Philips catalog,
on a different third-party site:

http://www.k-a.co.il/sites/katsenshtein/_media/catalog_product2/4553_cp_file1_7ac75.pdf

This PDF only lists the "13713X/98" type, with the following info:

Type V W Base CCT K Ordering number
13713X/98 235V 1000W X 2450 9238 960 44500

Looking at some of the other lamps in the table in this PDF, no "/98"
seems to indicate a clear lamp, while "/98" indicates a lamp with
reflector.

Finally, the same search yields this PDF

http://www.dr-fischer-group.com/img_pool/file/DF%20IR%20Catalogue%20final%20small.pdf

which seems to say that "Dr. Fischer Group" bought out this part of
Philips' lamp line in 2008. Page 22 of that PDF has the following info:

Type no. V W Terminal CT K* Ordering number Tube
13713X 235 1000 X-clip 2500 9238 515 43916 clear
13713X/98 235 1000 X-clip 2400 9238 960 44516 with white reflector
* labeled as "colour temp. K"

NIR halogen lamps usually have a CCT of ~2200-2400°K (at least the
unfiltered 'Halogenheat' Thorn types I used to work with were such).
