I purchased a desk lamp. The one I have has the ability to bend in three different places. The light bulb holder also rotates. I also switched out the light bulb to have an Ott Light Bulb, or full spectrum light bulb. Ott is a brand name.
Important thing to watch when using the Ott lights is using them late at night. If you find you're having trouble sleeping you may be light sensitive and need to test the light use with your system.
The good thing when using the Ott light or full spectrum bulbs is that they are true color. This can be important when trying to select or match fabric and their colors.
Another option is to use a pole light where the light is reflecting back from the ceiling rather than just focused downward. The light reflection could mean you need additional lighting. Can you change where the cutting surface is by moving the table?
Keep us updated with your problem and any solution you find.
