New LED Street Lamps coming to Abbey Ward , Derby
Originally published by Derby Liberal Democrats
The Council has started fitting new LED lights onto existing lamp posts.
The lights have a very directional beam compared to the previous lights. The brightness of the new lights can be lowered and raised during the hours of darkness.
This is the usual pattern: at switch-on until 8pm the lights are operating at 100%. Between 8pm and 11pm the lights are operating at 70%. Between 11pm and 6am the lights are operating at 40%. Between 6am and switch-off the lights are brought back up to 70%.
We have been told that the human eye cannot detect the difference between 70% and 100%.
If you notice any problems with any of the street lamps in the Abbey area, you can get in touch with local campaigner Ajit Atwal.
