Let's discuss a couple more elements of this landing page.
Design and colors.
It would be a bit counterintuitive to design a landing page about red light therapy around any other color than red, right? So, red it is – omnipresent on this landing page. I especially like that red is combined with white. If it was black instead of white, the page would look like a nightclub ad. This way, it's much more of a medical thing.
Opening section.
It was a good idea to include a video of a lamp user. It shows that using the device is easy, that everyone can do it, and that the lamp does not take away much space in one's room.
