Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-66ada69e3440c924 quantitative
Tallinn has been converting its street lighting to LEDs since 2014
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The city's own article states the LED rollout began in 2014: 'The widespread uptake of LED lamps in Tallinn started in 2014.'
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. City of Tallinn — Tallinn deploys LED lights, saves hundreds of thousands yearly
Claim 2 clm-516a00e92e7da361 quantitative
by March 2026 about 64% of its roughly 72,700 luminaires were LED
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The Estonian trade-press article (18 March 2026) states: 'Linnas on kokku 72 681 tanavavalgusti, millest 46 272 ehk umbes 64% on juba leedvalgustid' (there are 72,681 streetlights in the city, of which 46,272, or about 64%, are already LED).
Caveat
This figure is reported by an Estonian trade-press outlet (Elektriala, partly paywalled), not by a City of Tallinn publication. The entry's parenthetical '(city figures)' at the end of the sentence implies a more direct city source than what is actually cited for this number.

Sources carrying this claim

  1. Elektriala — Tallinn renews street lighting and builds a smart lighting management system
Claim 3 clm-10ca1b4874a05bc1 quantitative
the city put the saving at over 4,000 MWh a year versus 2019
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The city's own article (26 January 2022) states: 'The energy consumption has been reduced by more than 4,000 MWh compared to 2019.'
Caveat
This savings figure is from the City of Tallinn's January 2022 article, which describes the city's 2021 status: 66,993 total luminaires, 25,386 LED (37.9% LED share) — far below the 64% figure the entry pairs it with for 2026. No source in this entry gives an updated MWh-savings figure for the higher 2026 LED share; Elektriala's 2026 article, which is the only source for the 64%/72,700 figures, reports no energy-savings number at all.

Sources carrying this claim

  1. City of Tallinn — Tallinn deploys LED lights, saves hundreds of thousands yearly
Claim 4 clm-d329ce5edf7b0267 descriptive
adaptive Cityntel/Lumoflex controllers dim lights by weather and traffic
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Invest Foresight (2 November 2017) quotes Cityntel's founder describing Old Town lights that are 'automatically adjusted depending on weather conditions and street traffic density.' Lumoflex's own case-study material (accessed via cached search results after the live page returned HTTP 503) states Cityntel has installed about 600 Lumoflex smart controllers in the Old Town/City Centre of Tallinn, running the Lumoflex City platform as the management system — confirming the vendor identity and location, though Lumoflex's own text describes dimming by 'ambient light conditions' rather than explicitly 'weather'.
Caveat
This adaptive layer covers only about 600 of the city's roughly 72,700 luminaires (well under 1%) — a small Old Town/City Centre pilot, not a citywide system. 'Invest Foresight' is an investment/business-marketing publication, not independent journalism: the article is built around an interview with Cityntel's own founder, so it is effectively the vendor's self-description rather than a neutral evaluation.

  2. Lumoflex / Cityntel — Tallinn case
Claim 5 clm-987085c7e2c5d968 descriptive
with remote fault detection
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Invest Foresight states the system 'monitors the health of lamp and reports back failures and statistics.'
Caveat
Sourced only to Invest Foresight, an investment/business-marketing publication interviewing the vendor (Cityntel), not an independent evaluation.

Claim 6 clm-88ebda53db4fe848 quantitative
A full citywide smart lighting management system is planned for the 2026-2030 period
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The article (18 March 2026) describes plans to implement a 'sustainable and multifunctional urban lighting management system' during the 2026-2030 strategic period: 'rakendada jatkusuutlikku ja multifunktsionaalset linnavalgustuse juhtimissusteemi.' It is explicitly described as planned, not yet operational.
Caveat
As of this source's publication (18 March 2026) and the entry's verification date (25 July 2026), the system remains at the planning stage; no source in this entry establishes whether implementation had begun by either date.

Sources carrying this claim

  1. Elektriala — Tallinn renews street lighting and builds a smart lighting management system
Claim 7 clm-0c01bdfbf24b1a0d quantitative
about 64% of roughly 72,700 luminaires converted by March 2026
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The Estonian trade-press article (18 March 2026) reports 72,681 streetlights citywide, of which 46,272 (about 64%) are already LED.
Caveat
This figure is from Elektriala trade press, not from a City of Tallinn publication, though the sentence attributes it to 'city figures.'

  1. Elektriala — Tallinn renews street lighting and builds a smart lighting management system
Claim 8 clm-f1a1f6a139650366 quantitative
over 4,000 MWh a year versus 2019
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The city's own article (26 January 2022) reports energy consumption reduced by more than 4,000 MWh compared with 2019.
Caveat
This figure describes the city's 2021 status (37.9% LED share), not the 64% LED share this sentence attaches it to for 2026. No source gives an updated savings figure for the higher 2026 LED share.
