Michael in Customer Service was Very Helpful
One of the two bulbs I received initially was defective, so I was concerned about inserting the second bulb. But I spoke with a young man in Customer Service, Michael, who was very reassuring. Bottom line: the second bulb is fine and Michael arranged to have the defective bulb replaced promptly. Michael is an excellent representative of your company. I hope he is recognized and rewarded appropriately. (I spent my career in HR and know how important it is to recognize and reward excellent job performance.)
