Interesting article. Good to have all on one page. However, it does not alter my previous conclusion: These terms are highly context dependent. One should always refer to the context/spec when using these terms technically. And, the article should be more precise about the terms power and energy :stuck_out_tongue_winking_eye:.

I became uninterested when multiple sections mentioned HSL. As @chris said, it could be more precise (accurate?), though it is great to have all that on one page. Elaboration and examples would have been nice too.
