This LED lighting with 60LED module was done for a 500 no.s apartment complex in the lower basement. Sunlight does not enter a major part of the the lower basement hence tubelights are 'ON' 24 hours a day. Moreover when the power failed it was very dark (safety issues) until the generator started.
The picture
1 - taken with the camera flash 'on'.
2 - taken with camera flash 'off ' & surrounding tube lights 'on'.
3 - taken with camera flash 'off' & surrounding tube lights 'off'.ie; Battery mode where LED's are lit at the brightest level.
