I have a Craftsman 12″ band saw, and the bulb in the worklight protrudes past the end of the lamp, and it was reflecting off my glasses. I took a screw-on lid from a plastic Kool-Aid container. It has a 2″ indention on top of the lid, which I cut out for air flow around the bulb. The lid fits perfectly on the lamp. It makes a defuser to stop the reflection.
