Notes
- MR16: Ø51 mm, 55 mm maximum overall length, GU5.3 base — figures from the Philips 8.5MRX16/LED/F25 2700 DIM AF datasheet.
- The shape code gives the diameter in eighths of an inch (MR16); 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).
