The differences between xenon lamps d1s and d3s are as follows: 1. Numbers: The numbers 1 and 3 indicate the presence of a starter. 1 has a mercury design; 3 represents a mercury-free design. 2. Letters: S indicates suitability for lenses. D1 has a voltage of 85V, while D3 has a voltage of 45V. D1S comes with a built-in relay, while others do not. D3S is mercury-free due to environmental requirements. D1S can be used with the same ballast, and D3S can also be used with the same ballast. D1S has the same design, while D3S is an improved, eco-friendly version of D1S. D1S has higher brightness and a whiter color temperature compared to D3S.
