LED Tip 18: Cost Savings when Replacing 1000w HID with LED




This is the second tip we dedicated to cost savings. The first was associated with the savings in replacing 400W HID with an energy efficient LED Solution. In this tip we talk about the cost savings associated with converting a 1000W HID fixture over to LED, and the savings are even more stunning.



The Savings when you convert from 1000W HID to LED

Many fixtures in commercial and industrial applications use a 1000W HID bulb, including interior high bays as well as outdoor flood lights, parking lot fixtures, high mast lights, stadium lights and shoe box lights, to name a few.

We know that a 1000W HID bulb used 1150 watts when you also include ballast draw (the energy the ballast consumes).

But what does that mean when you convert to LED? How much money can you expect to save, per fixture, per year when you convert?

Well that depends on what the wattage of the LED solution is. Here are 3 examples.

Always remember, do a photometric first to determine the best option, and then use this guide to determine your savings.

In all 3 cases, we assume a run time of 12 hours a day, 365 days a year.

Case 1: 280W LED

Case 3: 450W LED Solution

450 LED Watts replacing 1000 Watts for 12 hrs/day 365 days/yr saving 3066 kw/year *

As you can see, the savings is significant. Multiply this by the number of fixtures you have, and if you want, multiply by 10 to calculate 10 years worth of savings.
