"I am interested for change lighting in our plastic bag factory, we use now 400W high pressure mercury in low bay lighting fixture. Our room is 24x36meters, one high side we have 10 meters, installation height abour 6-7m." Customer said

Total 20pcs 400W HPS in current plastic bag factory. 150W LED high bay light replacement for 400Watt HPS low bay lighting fixture to achive 400lx on the working area. 

How to calculate the payback?

Customer from Germany, the cost for one kilowatt-hour is very high, about 0.2869 Euro, it is about US$0.31818.

 

How to calculate the power consumption for my lights?

This is simply the number of luminaries multiplied by the number of watts for your type of fixture. For example if you have 20pcs 400Watt HID high bay fixtures in your garage, you can simply multiply the following:

20 fixtures x 454kWh =9,080 Watts

How many kilowatts?

Now take your total watts and divide by 1000 to get your total kilowatts. Using the example from above:

9,080 Watts /1000= 9.08 Kilowatts

 

How many house are you lights on every year? We turn ON-OFF 250 times per year and need to use 2500 hours per year.

 2500hrs per year =10 hours per day

To find total kilowatt/hours (kWh) we multiply:

9.080 kilowatts x 2500hours per year = 22700 kWh

What is the cost of your Energy? The cost for one kilowatt-hour is very high, about 0.2869 Euro, it is about US$0.31818.

 22700 x 0.31818 = 7772.686 USD per year in annual energy costs

How to calculate the payback? The cost of each LED lamp plus shipping cost and import VAT.

Do you know how long you can get back your invest for new LED high bay lights? Usually within 1 year!
