I want to know the answer to the following question:
When was the first electric light installed in the Eastern Market?
All the background I'm provided with is that "In 1880 a telephone exchange was established and in the same year the foundations of St Paul's, were laid; in 1881 electric light was installed in the Eastern Market, and in the following year a generating station capable of supplying 2,000 incandescent lamps was in operation.". Is that enough to answer the question?
