This little article comes from the Opelousas Courier of April 22, 1893. It lists the cost to light a home in Monroe:
The Monroe Electric Light Company shows up quite favorably in its charges, and as a consequence will prove a great public benefit. For 16-candle power all-night incandescent lamps at residences, the charge ranges from $3.50 for five lights per month to $10 for thirty lights. For offices and business establishments where constant use may be required, they cost $1 per month for each lam. – N.O. Daily Item.
