4.2 Activating Lights (Pen Tip & Pen Clip)
The pen tip light and pen clip light are controlled by the tail switch. This design allows for easy access to illumination when needed.
- Pen Tip Light: This light illuminates your writing surface, ideal for nighttime reading or writing in low-light conditions.
- Pen Clip Light: This light can be adjusted from 5 to 120 lumens, providing versatile illumination for various tasks. It's useful for general lighting or hands-free operation when clipped to a pocket or surface.

The green beam is activated by sliding up and holding the bolt action mechanism. This feature is useful for presentations, pointing out objects, or even as an interactive toy for pets.
Safety Note: The output of the green beam is 0.39mW, classified as Class 1, and is within the safe range, posing no harm to humans or animals under normal use conditions.
