| USE | KS Standards Performance Measurement | Total flux, Color temperature, Color Rendering index, Luminance efficiency, Power consumption, Power factor, Harmonics distortion |
|---|---|---|
| Q&C | Quality control | |
| R&D | Measurement for improving product performance | |
| Feature | Integrated | Measurement both KS standard and performance items as one equipment |
| Convenience | Easy to mount equipment to measure and save the data | |
| Compact | Sufficient space required 2m x 2m, provides its own darkroom | |
| Reliability | Accurate measurement optical and electrical properties by spectrometer and power analyzer | |
| Diversity | Possible to measure various DUT (flat displays, straight fluorescent lights, bulbs, MR, PAR, street lights, security lights and so on) | |
| Economic | Great price less than one spectrometer price |
