EISA Energy Efficient Lighting Standards
Warehouse in Mchenry converts to LED High Bay, saves 21k per year
You get out, What you put in….
I read this Tweet from retired NFL Player Brian Urlacher at
@LouieVito talking to that Little voice in his stomach.
As a native of Chicago, Brian Urlacher is someone I follow on Twitter, and his Tweets are entertaining sometimes. The saying above kinda rang true for us at M Lite Solutions.
We feel that building owners get out what they put into it. You see building owners that want to save money, and upgrade to LED fixtures will save 60 to 80% in energy reduction just by doing the right thing and investing in themselves with energy efficient lighting by M-Lites.com.
100 LED High Bays can save in many ways…
Upgrading 100 400 watt Metal Halide fixtures to 150 watt LED High Bays will save our client in Mchenry, IL. in many ways. Let’s begin with the “Cost of Waiting”.
As you can see from the chart above the cost of waiting per year is $21,000 in annual savings. For every month they do not change out their lighting, it would end up costing them $1700 per month. The cost of the goods without labor is almost $38,000, which means our warehouse client in McHenry, IL. will hit a rate on return of investment within 2 years time. This is the type of cost effective savings a business owner can get out what they put in.
Warehouse Watt Summary
In addition to creating a better working environment with brighter lighting, our warehouse in Mchenry will reduce their energy consumption by 67%. Again, our warehouse owner is getting out, what they put in and more…
McHenry Warehouse Environmental Impact
Although the world’s climate changes happen naturally. We contribute to the pollution of the environment more than any other living thing on our planet. So many people are finally wondering how they can help reduce the emission of greenhouse gases into the atmosphere and changing your lighting to LED can reduce plenty (see the chart above). Since change will not happen overnight, lighting is a definite step that we can take in this fight against global warming.
Going Green with LED Lighting makes sense for all of us. Let M-Lite show you how you can do your part and start saving the world one light at a time. For more information visit us on-line at M-Lites.com
LED Terminology – Kelvin, CRI, and Luminous Flux
LED Lighting Terminology
Color Temperature and Color Rendering (Kelvin and CRI): There are two standard measurements for the color characteristics of light: “color rendering index” (CRI), a term used to describe the extent to which an artificial light source is able to render the true color of objects as seen by natural outdoor sunlight which has a CRI of 100, and “color temperature”, which expresses the color appearance of the light itself.
Color Rendering Index (CRI): Incandescent is used as the base reference of 100 CRI. Compact fluorescent lamps are graded at 82-86 CRI, which is considered high quality color rendering. CRI is a more important consideration for retail lighting design than it is for office lighting. Any CRI rating of 80 or above is considered high and indicates that the source has good color properties. Incandescent lamps and daylight have a CRI of 100, the highest possible CRI. The higher the CRI of the light source, the “truer” it renders color. At M-Lite we strive to manufacture our LED lighting at 80 CRI or better.
Color Temperature (Kelvin): Refers to the way color groups are perceived – the psychological impact of lighting. Color temperature is how cool or warm the light source appears. The color temperature of a light source is a numerical measurement of its color appearance. This temperature is based on the principle that any object will emit light if it is heated to a high enough temperature and that the color of that light will shift in a predictable manner as the temperature is increased. This system is based on the color changes of a black metal as it is heated from a cold black to a white hot state. As the temperature increases, the color would shift gradually from red to orange to yellow to white and finally to a blue white. Color temperature is measured in degrees Kelvin (K). Colors and light sources from the red/orange/yellow side of the spectrum are described as warm (incandescents) and those toward the blue end are referred to as cool (natural daylight). The sun, for example, rises at approximately 1800 Kelvin and changes from red to orange to yellow and to white as it rises to over 5000 Kelvin at high noon. It then goes back down the scale as it sets.

Luminous Flux – the flow of light measured in lumens. With light bulbs, it provides an estimate of the apparent amount of light the bulb will produce. Depending on the application, much of an incandescent’s light is wasted because it’s emitted in every direction. LEDs on the other hand, put out directional light, sending all of the light exactly where it’s needed. This is why an LED producing 500 lumens might be equivalent to an incandescent producing 900 lumens.
Lumens measure how much light you are getting from a bulb. The more lumens means it’s a brighter light; fewer lumens means it’s a dimmer light.
Lumens produced is just one factor of the performance of a light, and sometimes it is misleading. To understand how to fully evaluate the LED product, we need to look the overall system efficiency, optical control, thermal management of the LEDs.
Another factor that can also be very misleading is the life of an LED lights, the life time is defined by how long will the light last before the fixture reaches 20 percent lumen depreciation.
For example, most of the time an LED Light has a life time of 50,000 hours, it does not mean that after 50,000 hours, the LED lighting product will not work at all. It will still be working, but the Lumens it emitts is factored at 20% less than when it was first used.
