How SwingShift UV Energy Index Is Calculated
During the continuous-output test, the Linshang LS128 measures cumulative UV energy density. The instrument reports accumulated energy in millijoules per square centimeter (mJ/cm²).
Dividing by 1,000 converts the cumulative energy density from mJ/cm² to J/cm². The resulting numerical value is rounded to the nearest whole number and reported as the SwingShift UV Energy Index.
Calculation for this tested flashlight
329776 mJ/cm² ÷ 1,000 = 329.776 J/cm²
SwingShift UV Energy Index = 330
The SwingShift UV Energy Index is a derived comparison metric, not an industry-standard unit of measurement. It should not be confused with instantaneous UV irradiance measurements such as µW/cm².
Testing was conducted by SwingShift using consistent, documented procedures and factory-calibrated measurement equipment. Published results and derived metrics reflect the specific units tested, the recorded measurements, and SwingShift’s interpretation of those data.
