Notes
- BR40: Ø125.4 mm, 160.3 mm maximum overall length, E26 base — figures from the Philips 8.8BR40/PER/927-22/P/E26/WG datasheet.
- The shape code gives the diameter in eighths of an inch (BR40); the ANSI C78 envelope limits are paywalled, so a typical current product is quoted. Other brands differ by a few mm in length.
- The file is a cylinder envelope Ø × MOL (the bulb fits inside it).
