Do you have the full code that describes what kind of LED it has? (In the specs, on some receit, or packaging or whatever...) Given enough digits in the code, you may or may not find enough details to dig out color temp for that particular diode. Google is your friend here...

Example: A led of type "Cree XR-E" doesn't really tell you anything, those come in all kinds of color temperatures. But if there's additional digits you may have enough information.

Another source of information could be reviews for LD15, written about the same time as your purchase. They may have written something about color temp.

Fenix -- like most LED lights -- tend to be somewhere in the "colder part of the range "cold" to "neutral".
