Let’s all calm down, and behave like grown-ups. Flashlights using incandescent bulbs are still with us. Those of us who are pack-rats could stock up on bulbs for our flashlights. In addition, 50-100-150 incandescents will still be available. (I did stock up on those.) While we’re on the subject– what about LED’s. What effect do they have on gemstone color? Has anyone done any hands-on research on this?
