The Crystal Dome stands at a commanding height of 42’ from the top of the Temple Gopuram, embedded with 2500 Nos. of 1’ diameter crystals. During day time, when direct Sun Light falls on the crystals, the same is converted into a beautiful “Rainbow” pattern. In the evening, the crystals are illuminated by 27 Watt LED lights, each crystal disseminating 16 colour combination lights, forming 138 patterns. The total output works out to 67,500 Watts. The luminous capacity of the Crystal Dome ranges from 36,000 Lumina (at a minimum value of 18 per unit) to 3, 70,000 Lumina (at a maximum value of 186 per unit) and the power consumption ranges from 2KW to 54 KW.
