> Isn't that precisely what the spec already says? The note is pretty explicit that lux is one component of the value, and that screen tech/etc are also important. True, informative note has very good points, however, normative prose is bit misleading. For example, e-book reader during sunny day might return 'normal' while mobile device with TFT may report 'washed', yet, ambient light level would be exactly the same for two cases. Thus, following statement _"The light-level media feature is used to query about the **ambient light-level** in which the device is used,"_ is misleading, since ambient light level is the same. I think it would be good to redefine 'ambient light level' term (similar to CSS pixels vs pixels) or create new term to avoid confusion. For example: `For the purpose of this specification, the <dfn>CSS ambient light level</dfn> represents conditions in which device is used, such as illuminance level of the environment, screen brightness, screen technology and other factors affecting the contrast of the device's screen.` Or: `The information about <dfn>condition</dfn> in which the device is used may be derived from the factors such as: illuminance level of the environment, screen brightness, screen technology and other factors affecting the contrast of the device's screen.` `The light-level media feature is used to query information about the <a>condition</a> in which the device is used, to allow the author to adjust style of the document in response. The following values are valid:` /CC @anssiko the current ALS spec editor. -- GitHub Notification of comment by alexshalamov Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/1727#issuecomment-323002704 using your GitHub account
