Notes
- PAR38: Ø122.2 mm, 134.9 mm maximum overall length, E26 base — figures from the Philips 14PAR38/LED/840/F40/DIM/ULW datasheet.
- The shape code gives the diameter in eighths of an inch (PAR38); 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).
