IDK if this has been suggested yet, but I know how lame the stock incandescent lights are on the Oregon bench grinders [510-present], so I thought I would show a good replacement LED. They are a tight fit, but clear the rotating arbor with no issues. If it is too bright, you can stick some foil tape so it does not blind you as you use the grinder. Be safe!
