evidence: This claim is inaccurate. Marketing material for Lisburn Light Festival considerably overestimates the number of lights in the organised display. Our visual estimate of the main components suggests that there are around 200,000 lights, far short of the "over one million lights" estimate. Lisburn Light Festival runs from 22 November 2018 until 25 January 2019 and claims that "over one million lights will illuminate [Lisburn] City Centre". This claim appears online in Lisburn Today (Ulster Star), on the Lisburn and Castlereagh City Council’s website, and in the festival’s brochure. [...] Summing up these figures, we estimate that there will be around 200,000 lights in the seasonal display. This is considerably less than the 1 million lights advertised for the Lisburn Light Festival.
