This is how you add redundant non-information to a sentence: "semiconductor-based, solid-state LED lighting".

Someone who doesn't know what a LED is surely won't understand that "clarification". Marketing mindset!

Someone who doesn't know much about LEDs might come away thinking that these are extra special LEDs, much better than the normal LEDs they're used to, without the marketing team having to say anything that can possibly be challenged. Marketing mindset!
