Comprehensive Laboratory Testing

Integrating Sphere

Lumen Test

A lumens test rates the total amount of light emitted from a flashlight in all directions inside an integrating sphere.

  • ✓ Use a light meter to determine illumination levels.
  • ✓ Verify total light output against design specs.
  • ✓ Repeat with sample batch for reliable results.
Data Graph

Discharge Time

We graphically depict the flashlight's brightness over time to determine true battery life and runtime performance.

  • ✓ Automated battery tester analysis.
  • ✓ Check voltage sag and regulation curves.
  • ✓ Ensure terminals make perfect contact.
Water Testing

Water Resistance

The IPX rating system quantifies water resistance. As a survival tool, submersion capability is critical.

  • ✓ IPX8: Submerged 2 meters for 30 minutes.
  • ✓ IPX7: Submerged 1 meter for 30 minutes.
  • ✓ Vacuum seal integrity checks.
Climate Chamber

Temperature Assessment

Flashlights are placed in a chamber simulating varying extreme temperatures to observe any ill effects on electronics or materials.

  • ✓ Ensure surface temp stays below 48°C.
  • ✓ Extreme cold/heat cycling tests.
  • ✓ Battery safety validation.
Battery Testing

Battery Test

Verification of milliampere-hours (mAh) capacity. Shengqi Lighting relies on precise voltmeters to determine optimal charge states.

  • ✓ Capacity verification (mAh).
  • ✓ Internal resistance checks.
  • ✓ Overcharge/discharge protection test.
Mechanical Testing

Button Test

Automated pressing machines verify that buttons work properly at various speeds and efficiencies for both single units and production runs.

  • ✓ 50,000+ cycle life testing.
  • ✓ Test for sticking and bouncing issues.
  • ✓ Critical for tactile feedback reliability.
