Lenses of narrow to wide range are used on these fittings to spread light, he said.

A narrow beam lens has been used to highlight specific objects such as the lotus on the Jaipur Column and a wider beam lens to spread light on a larger area, he said.

Features that have been highlighted prominently in the lighting are the Jaipur Column, dome of the main building, chattris, fountains at terrace and ground level, as well as loggia columns, the official added.
