Abstract
This study evaluated LED color temperature preference and effectiveness in a task light setting for older adults with a comparison to younger adults. Test subjects included visually active adults, male and female, from 19 years to 96 years of age. The researcher tested one hundred participants from several test sites. The researcher ascertained conclusions based on the correlations of age, gender, visual acuity, time of day, and visual medical conditions to LED preference. A tunable lamp with four correlated color temperatures (CCT/K), 2700K, 3500K, 4100K, and 5000K was analyzed using timed and graded, reading and number comparison tasks. Lumen output between the correlated color temperatures was adjusted for consistency to prevent illuminance (lumens) from effecting the outcome. Test subjects choose a preferred correlated color temperature and completed a subjective survey accessing the preferred comfort level. Results indicated the test subjects performed better with the 4100K correlated color temperature. Regarding personal preference of correlated color temperature by test subjects on average: the 4100K correlated color temperature was preferred first (36%), the 3500K correlated color temperature was preferred second (28%), the 5000K was preferred third (24%), and the 2700K was preferred least (12%). A significant difference was discovered between men and women with men, on average, taking longer to complete the reading and number matching tasks than women.
