These are representative market ranges, not guaranteed limits. Availability varies by manufacturer, voltage, base, beam, region and product generation.
Measure the globe and total lamp length, then confirm base, voltage, finish, dimming, colour temperature and fixture clearance.
Globe designations are not applied identically in every market. Confirm the manufacturer’s stated diameter rather than selecting by the G-number alone.
Important: The library describes a lamp format, not a particular product. A shared shape does not guarantee matching voltage, base, dimensions, light distribution or control-gear requirements. Confirm the fixture label and product datasheet, or ask a Bulb World lighting specialist.
