ADL performance

All validation groups address the following ten ADL tasks in 9 different combinations of light temperature (in Kelvins - K) and light intensity (in foot candles - fc) in order possible differences to be revealed among the validation groups and light combinations: 1\. Phone Book Search (PBS), 2. Supermarket receipt (SupRe), 3. Book reading (BR), 4. Cellular message (CM), 5. Cellular entry search (CES), 6. Reading computer screen (RCS), 7. Drops bottle reading (DR), 8. Subtitles reading (SubRe), 9. Open door test (ODT), and, 10. Screwdriver test (ST). The 9 light combinations are the following: 3000 K - 25 fc, 3000 K - 50 fc, 3000 K - 75 fc 4000 K - 25 fc, 4000 K - 50 fc, 4000 K - 75 fc 6000 K - 25 fc, 6000 K - 50 fc, 6000 K - 75 fc
