**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- A19: Ø61 mm, 107.4 mm maximum overall length, E26 base — figures from the Philips 14A19/LED/850 ND datasheet.
- The shape code gives the diameter in eighths of an inch (A19); 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).
