Led Lamp Calculation

The document compares the electricity costs of mercury lamps versus LED lamps for a new plant area and street lights. For the plant area, 12 mercury lamps using 3000W would cost Rs. 3467.10 per month while 8 LED lamps using 1200W would only cost Rs. 1386.84 per month, saving Rs. 2086.26 monthly. Over 12 months the total savings would be Rs. 24963.12. For the street lights, 10 mercury lamps using 1500W would cost Rs. 2971.80 monthly while 10 LED lamps using 500W would be Rs. 990.60, saving Rs. 1981.20 monthly. Over 12 months the total savings from the street lights would be Rs. 23774

New plant M/C area

Mercury lamp 12 nos X 250W = 3000 W (3 Kw)

1 Kw /1 hour = 1 unit

Working hours = 7 hours

3 Kw X 7 hour = 21 unit

1 unit E.B Rate = Rs-6.35

21 X 6.35 = Rs-133.65

26 days X133.65 = Rs-3467.10

LED Lamp – 8nos


8nos X 150 W = 1200 W (1.2Kw)

1.2 Kw X 7 Hours = 8.4 unit

8.4 unit X 6.35 = Rs-53.34

26 Days X Rs-53.34 = Rs-1386.84

12 nos Mercury lamp E.B unit price = Rs-3467.10

8nos Led lamp E.B price = Rs- 1386.84

Monthly savings = 2086.26

12 month X Rs-2086.26 = Rs-24963.12

1 LED Lamp Price – Rs -7500

8 nos Led X 7500 = Rs-60000


Side street light - 10 nos X 150 W =1500 W (1.5kw)

Working hours = 12 hours

1.5 KW X 12 hours = 18 unit

18 Unit X Rs-6.35 = Rs- 114.30

26 Days X Rs-114.30 = Rs-2971.80

LED Street light – 10 nos X 50 W = 500 W (0.5 kw)

0.5 Kw X 12 Hours = 6 unit

6unit X Rs-6.35 = Rs-38.10

26 Days X Rs-38.10 = Rs-990.60

Mercury street light E.B unit = Rs-2971.80

LED lamp E.B unit =Rs -990.60

Savings per month = Rs-1981.20

12 month X 1981.20 = Rs-23774.40

50 W LED Lamp = Rs-5000

10 nos X Rs-5000 = Rs-50000
