Yes. I'm aware. I have one. It's just a bit cumbersome despite being one of the smallest you can find. I'm thinking of something smaller and integrated into the case, not clip on. Most of the space and weight in a booklight is taken up with the housing and the clip, not the bulb or the electrics. You could integrate the lighting into the case without much added weight and you wouldn't have a second item to carry around with you.
