LED Light Bulbs Save Energy on Mysore Palace Board


As the first step towards the conservation of energy, The Mysore Palace Board began working with the replacement of equipment outside the halls of the palace (along the tracks and walk to the door) with Eco-LED (light emitting diode of light). 12 volt led lights will be enough.

As part of the first stage of labor, 685 units were replaced with LED lights to a golden color, as desired by the Council of the palace.

The contract was awarded to a man named S. Mysore Nagaraj, CEO of green light Trishul, Bangalore.

Star of Mysore Nagaraj said the Rs 77 lakh contract for the replacement of more than 3,000 lights on the Palace Square, which will be implemented in five phases. "Each LED unit is guaranteed for 50,000 hours," said Nagaraj and added, "the unit cost of Rs 30 watts. 14 000 and 60 watt unit cost of Rs 28000th service and replacement guarantee has been issued for five years. "

Nagaraj said the LED lights with LED other contractors that submitted bids were reviewed by representatives of the Board of Directors of NIE engineers and technicians Palace before awarding the contract. They insisted on using a light outside the Palace of Golden Hue.

".. The main advantage of energy saving LED lamps produce more light on the production of electricity used for LED bulbs are a great power, consumes less electricity," said Nagaraj, adding LED lights have the stabilizer circuit voltage , which takes the voltage range of 90 to 270 volts. They are also recyclable, he said.
