 However, with over 520 gas jets the chandelier was very expensive to light and in 1886 the chandelier was using electricity installed by Magnus Volk alongside gas.In 1888 the central chandelier was taken down, thought because of the expensive running costs; however customers reported the room was now too dim and so parts of the chandelier were rehung.In 1900 the chandelier was rehung in the Concert Hall as it was thought to strengthen the roof but its return was short-lived.
