I suppose there was a period of time that this fact was accepted. Take a look at [1], and then [2]. There is a difference of two years between the articles. There might be some out of date articles still on the web promoting that this is a true statement.

Given that the main idea behind the product is to produce light without any standard energy sources, and not "a new bug repelling lamp!", I would give them the benefit of doubt. Also, the people behind the lamp are regular designers, not a big company which had all the time and energy to verify everything in the article.

Note: I respect your catch. I'm not promoting such misstatements in promotion videos, but the word "lie" is farfetched. Too harsh. Especially with all the other bashing going on here.
