150W LED High Bay Light vs 400W High Pressure Sodium
2017-03-17 18:41:54

I want to replacement for existing 20 400W High pressure sodium high bay lighting fixtures by LED lights. But there are so many fixtures on options, T5, T8 fluorescent and LED high bay light, what is the best lighting source for replacing current old 400W HPS?  It’s a furniture factory where workers make montage and other jobs, not just warehouse.

HID vs. LED

Our room is 24x36meters, total height 8m, what your recommend to use if our lights are 6 meters high ? We turn ON-OFF 250 times per year and need to use 2500hours per year.

Old 400W HPS fixtures

The only way to determine what is the best lighting source for replacing your existing old lighting fixture is to do a lighting layout. Simply make a analyzing layouts, could help you save money to try different samples.

According to industrial standards of furniture lighting level, working area 300-500lx, assembly area 300lx. Check with lighting simulation software, after calculation, you can use 150Watt LED high bay light to replacement 400W HPS high bay lighting fixtures. Simply one-for-one swap of your old fixture. You do not need to upgrading your circuit, simply one-for-one swap of your old lighting fixture by LED high bay light. Easy for installation.  

Existing 150W LED High Bay Light Create Better Light

How to calculate the energy cost of lights?

1.       Wattage:

A typical 400W High Pressure Sodium fixture uses 458 Watts

A typical 400W HPS replacement LED lamp uses 150 Watts

2.       Existing fixture quantity

In this project, customer use total 20 400W HPS lighting fixtures in his facility. Simply point-to-point replacement for existing lighting fixture.

400W HPS = 20 EA

150W LED = 20 EA

3.       Total Power consumption

HPS: 458 Watts x 20 fixtures = 9160 Watts

LED: 150 Watts x 20 fixtures = 3000 Watts

4.       Kilowatts

Watts divide by 1000 to get kilowatts

HPS: 9160 Watts ÷ 1000 = 9.16 Kilowatts

LED: 3000 Watts ÷ 1000 = 3 Kilowatts

5.       Operating hours per year.

In this project, our customer run 10 hours per day, and around 2500 hours per year.

6.       Total Kwh per year

Simply use Kilowatt-hours multiply operation hours:

HPS: 9.16 Kilowatts x 2500 hours = 22900 Kwh per year

LED: 3 Kilowatts x 2500 hours = 7500 Kwh per year

7.       Operation cost per year

HPS : 22900 Kwh x $0.1 = $2290

LED : 7500 Kwh x $0.1 = $750

8.       Total LED savings per year

$2290 - $750 = $1540 (Total LED savings monthly: US$128.33)

9.       Month to reach return on investment:

LED cost multiply LED quantity divide by monthly LED monthly savings, for example: LED high bay cost plus shipping cost and Tax, US$120 per fixture

U$120 X 20 Fixtures ÷ $128.33 = 18.75 Months

10.   Total LED Saving Percentage:

(458 Watts – 150 Watts) ÷458 Watts x 100%= 67%

Cut your Annual energy by 67% with LED high bay lights.

The return on investment is quite quickly, usually under 19months, less than 2 year. TEKLED high bay light provide 5 year full performance warranty, it is very cheap to maintain and run. LED lifespan consider to 54000 hours. Pair that with much longer life and your can continue to reap the benefits year after year.I want to replacement for existing 20 400W High pressure sodium high bay lighting fixtures by LED lights.
