3-in-1 Versatility – Choose Your Version

The ST3 combines three functional lighting systems in a compact penlight design. The specialized third function depends on the selected version.

Spotlight

The front spotlight delivers up to 1450 lumens with a 14100 2000mAh rechargeable Li-ion battery.

Its focused beam is suitable for everyday illumination, equipment inspection, and outdoor use.

Adjustable White Floodlight

The integrated side floodlight provides broad, comfortable illumination with:

• Stepless brightness adjustment

• Adjustable color temperature from 2700K to 6500K

• Warm white for comfortable close-range lighting

• Neutral white for everyday tasks

UV fluorescence depends on the material being inspected. Not all substances will react visibly under 365nm illumination.

Please select the desired version when ordering. Red Laser and 365nm UV are alternative configurations, not simultaneous functions.
