- Using the Sturdy Clip: The base of the light features an integrated clip. Open the clip and attach it to the edge of a tabletop, book, or other suitable surface. Ensure the clip has a firm grip.
- Using the Adhesive Mount: For a more permanent attachment, particularly to a sewing machine, use the provided adhesive strips.
- Clean the desired mounting surface thoroughly to ensure it is free of dust and grease.
- Peel the backing from one side of an adhesive strip and apply it firmly to the flat surface on the back of the light's base.
- Peel the remaining backing from the adhesive strip and press the light's base firmly onto the cleaned surface of your sewing machine or workstation. Hold for 30 seconds to ensure adhesion.
- Allow the adhesive to cure for several hours before applying significant stress to the mount.

- Adjusting Position: Use the flexible neck to position the light head as desired. The neck can be bent and rotated to direct illumination precisely where needed.

- Using the Book Light: When the book light head is attached, position it to illuminate your reading material. The low-glare light is designed for comfortable reading.
Maintenance
