[Inolux](https://www.digikey.com/en/supplier-centers/inolux) is a focused supplier offering a variety of LED solutions in many different form factors. We’ve had some questions recently concerning the MSL value for these products, all of which are higher (worse) than they were a few months ago. Is this an error? What gives?

Inolux has recently changed how they handle MSL for their devices, as laid out in [this PCN](https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/8888/PCN_IN-260213-01.pdf). All parts are considered MSL 3 by default unless specifically called out otherwise in their datasheets, and Inolux has doubled the recommended bake time for products that require baking. These changes aren’t considered a significant change, and are more a clarification of how Inolux’s products already worked.
