LED lighting installed in London road tunnel
Projections show that the cost of lighting the Upper Thames Street tunnel could fall from around GBP 50,000 each year to less than GBP 10,000. The LED lights are expected to last for 20 years, as opposed to the existing system's two-year life span, significantly reducing the need for maintenance closures. Also, the tunnel lights will cut CO2 emissions by more than 60 per cent.
