2. Executive Summary
LED technology: More than 30 years, LEDs have been used in a variety of
areas including industrial systems, car lights, advertising, and Street lights.
Long life expectancy: 20 to 25 years for LED v 3 - 6 years for conventional
lighting, means reduced maintenance costs, fewer lamp renewals and less
inspection and physical monitoring.
Demonstrable health and safety benefits: More focused light improves night-
time visibility which can reduce vehicle accidents and crime, with less
spillage onto residential properties. (The UK Green Investment Bank, 2014)
Main Target is Birmingham City Council, once this trial is successful this will
allow us to roll out this project to other counties.

3. Costings
Product Price INCL VAT Price for 6.66 M
LED 20 watt £ 112.80 £ 751.248 M
LED 60 watt £ 138.80 £ 924.408 M
PIR sensor £ 2.00 £ 13.32 M
Pi Zero £ 15.00 £ 99.9 M
Pi camera V2 £ 21.00
20 Watts lamp
One day cost in pounds
20 W X 10 h X 0.12/1000 = 0.024
One year cost in pounds
0.024 X 365 = 8.76
Number of streetlights in UK
7.4 million
7.4 million LEDS cost per year
7.4 X 8.76 = 64.824 millions
60 Watts lamp
64.824 X 3 = 194.472 million
Difference between 20W and 60 W LEDs
194.472 – 64.824 = 129.648
If we use 20 w LED we could save £ 129.648
million per year
According to GIB research, less than 10 % are
currently using low energy LEDs in UK,
Therefore 90% of street lights need to be changed
90/100 X 7.4 million = 6.66 million street lights
• Lights used on average 10 hours per day
• 1kW h cost £ 0.12

4. Phase 1 and 2
Phase 1 convert all 6.6 million public street lamps to
LED this will provide energy cost savings for Phase 2
funding.
Phase 2 will be to add the PI cameras onto the
lamppost which will allow for smart parking increased
safety and reduce energy usage further.
