I imagine you could work with something like this.
VAVOFO Rechargeable Reading Light, 7 LEDs with 9 Color Temperature 9 Brightness Levels Clip On Book Lights for Reading in Bed with Power Indicator for Bookworms (Black) https://www.amazon.com/dp/B07S79Z7Z5/ref=cm_sw_r_apan_glt_fabc_8NR4DFF1NT0X8B7C9SJZ?_encoding=UTF8&psc=1
I’m not sure to be honest, there is no name on it. What works for me is a light that clips onto the book, the light is on a adjustable arm, and you can manipulate the brightness.
The adjustable arm is important to aim it away from my wife or the tv (because the glare bothers her).
something like this (I’m not recommending this particular brand)
A book light or two might also be an option to consider.
The problem is that pens with gimmicks like that tend to be bad at being a pen. Not exactly what you asked, but I would just put a dim book light on the journal.
