What T10 tells you
- Shape
- wide tubular lamp
- Nominal diameter
- 1.25 in (32 mm)
- Typical bases
- E26, G13

The diameter is part of the naming system, not a full dimension drawing. Individual models can differ in overall length, neck profile, optics, and manufacturing tolerance. Use the maker's drawing when the fit is close.
At the fixture
Four other details to record
- Read the base code and voltage on the old lamp or fixture label.
- Compare the published maximum diameter and overall length with the available space.
- Record lumens, beam angle where relevant, color temperature, and dimming behavior.
- Look for the enclosure, location, temperature, or vibration rating required by the fixture.
