It has a smaller Luminous Cavity, so it's lower power but high cost-effective, also has a smaller Focal Spot.

Optical Power: 1,000-1,600mW

Voltage: 5-6V

Electric Current: 1.1-1.35A

Wavelength: 445±5NM

It has a longer Focal Length, so it has a longer Depth of Field, but a bigger Focal Spot.

Optical Power: 4,500-5,500mW

Voltage: 4.2-5.0V

Electric Current: 3.4-3.6A

Wavelength: 445±5NM

It has a shorter Focal Length, so it has a smaller Focal Spot, but shorter Depth of Field.
