I do most of my reading on a Kindle at night, which has prevented me from reading paper books, which I have become nostalgic for. I bought this inexpensive Glocusent bookmark-style light, which has three color temperatures (I use amber), a tilt-swivel light, and five brightness levels. It's small and unobtrusive, and the USB-C rechargeable battery lasts weeks of nightly reading. — MF
