From what I know and have heard, those two are the best 2x AAA torches available. The Streamlight Stylus Pro has the advantages of being simple to operate and affordable to purchase. The Preon II offers the versatility and power of having multiple modes and a high maximum brightness level for its size. I'm not sure what to recommend outside of these two lights. Maybe others can chime in with some ideas.

A light pen is an optical device that detects light emitted by a computer screen to determine the position of the pen on the screen. It is used as an input device to interact with computers by pointing, clicking, and drawing on the screen.
A light pen works by detecting light emitted by a computer monitor or screen when the pen's tip touches the surface. The pen has a light-sensitive photodiode at the tip, which detects the light and sends a signal back to the computer to identify the pen's position on the screen. This allows users to interact with software by pointing and selecting on the screen.
A light pen operates by detecting the light emitted from a computer screen when activated by a user pressing the pen against the screen. The screen emits electron beams that are picked up by the light pen, allowing the computer to determine the location on the screen that the pen is pointing at.
