quantitative
In September 2014 the City of Milan and the utility A2A announced that all 141,000 city-managed street lights would carry LEDs by August 2015, with 80% of them done by the opening of the Milan Expo that May
clm-ef72a0cebe6cec20
descriptive
the first large Italian city to be lit entirely by LED, as the announcement put it
clm-f6c2616354ee0b40
quantitative
A2A's own project page reports the retrofit as 136,000 luminaires, at a colour temperature of 4000K, a rated life of 50,000 hours and 100 lumens per watt, with no light emitted upwards
clm-7530ac5fbdba1abb
quantitative
A2A, the utility that carried out the retrofit and the only party to have published a result, reports that it cut electricity consumption for public lighting by more than 50%, equivalent to more than 11,000 tonnes of oil equivalent saved a year, and avoided more than 23,000 tonnes of CO2
clm-9131873ff4cb347a
descriptive
No baseline year, measurement method or independent check is given with those figures
clm-05780029bc7a9a85
quantitative
The per-capita consumption falling from 87 to 42 kilowatt hours, the €10 million the city stood to save in the first year, the €38 million A2A would invest over two years: all of it was said in September 2014, before a single lamp was counted, and all of it is written in the future tense in the report it comes from
clm-dd45365272210ac0
quantitative
the two accounts do not even agree on how many lights there are: 141,000 planned, 136,000 reported
clm-70422ffb86c9e64e
descriptive
It sets out the lamp, its colour temperature, its life and its efficiency, and the energy that saves; there is nothing about dimming, scheduling or fault detection
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.

src-8f0164d26d1bb741Press, read in full. Every figure is stated as a plan: 141,000 city-managed lights 'scheduled' for LED by August 2015 with 80% done by the Expo opening in May, per-capita consumption 'expected' to fall from 87 to 42 kWh, the city 'stands to save' 10 million euros in the first year, A2A to invest 38 million over two years.
src-f74bafd55738ee7aOperator/official, read in full: '136.000 apparecchi installati nel territorio cittadino', 4000°K, 50.000h, 100lm/watt, 'nessuna emissione verso l'alto', 'ridotto di oltre il 50% il consumo di energia elettrica corrispondente a più di 11.000 tonnellate equivalenti di petrolio risparmiate all'anno' and 'evitata l'emissione di oltre 23.000 tonnellate di CO2'. The page carries no publication or update date, hence date: null. It says nothing about remote control, control boards, dimming, scheduling or fault detection.
