Observations With the Vekkia Bookmark Light (And Discussing Book Lights in General.)
I recently purchased the [Vekkia Bookmark Light](https://www.amazon.com/LuminoLite-3000K-Bookmark-Adjustable-Brightness/dp/B08PTSZXG9/ref=sr_1_5?crid=WIVROEKRTSZP&keywords=vekkia%2Bbookmark%2Blight&qid=1677193545&sprefix=vekkia%2Bbookmark%2Blight%2Caps%2C211&sr=8-5&th=1). It's not a perfect device, but I think that the Supernote does like having an external book light and this is a relatively good one. It's basically a bookmark with an internal metal ribbon so it holds it's shape when you bend it. The box also includes a clip, which allows you to clamp it into place on a device or a book. Frankly, I think the clip is largely unnecessary, as there are ways to use it with the Supernote without a clip. Mine has three color modes (white, warm, orange). It appears to be the same model My Deep Guide (Youtube) covered when he covered it.
Glare is present, but only mildly annoying and entirely usable as-is. That said, I am looking at how to put a DIY diffuser on the light.
If you have a folio on your Supernote, you don't really need the clip. The bookmark part of the light has a U-shaped bendable plastic piece and an I-shaped tongue with the USB charging connector on it. If you split them, you can thread the USB charger between the folio and the back of the Supernote, slide the U-shaped section behind the folio, then fold the front of the folio around to the back to sandwich the light in place. Technically, this requires tension--you have to actively pin the folio to the book light--but unless you're on an airliner flying through a hurricane the tension requirement is trivial and you get plenty of tension holding the Supernote with one hand. (Using this technique a lot may fray your folio, however.)
