The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".

      Service and delivery comments:

      I have used other companies in the past and have often encountered difficulty getting the specialty bulbs and other products we need. In fact we have a bulb specialty wharehouse two blocks from our facility that I no longer use because customer service was not their primary concern. So as a purchasing manager I searched for a company that provided quality customer service, competitive pricing, and a user friendly website. I found Bulbs.com to be above and beyond my expectations in every department. I would, do and will recommend them to anyone. Thank you for your excellent service and attentiveness to us your customers.
