Color rendering and color appearance are the most crucial aspects of lighting quality for LED luminaires. Below is more information about each of them.

Color appearance

This is communicated by use of correlated color temperature commonly shortened as CCT on the Kelvin scale. For the interior lighting applications, the warm white should range 2700 to 3000 kelvins and in some cases the neutral white is about 3500 to 4000 kelvins. The cool white LEDs have high CCT and thus tend to give higher efficacy at a lower cost. It is bluish in color. However, expectations of the user may not be met. Of late the number of the high efficacy LED luminaires has been increasing and thus they are available in both neutral white and warm white colors. Two light sources having identical CCTs may render the object colors differently due to differences in spectra. CCT provides a good indication of whether the light source will appear yellowish or bluish. Duv is an additional metric which can assist in identifying sources with pinkish or greenish hues.

Color rendering

It is also referred to as color rendering index or CRI. It is used to measure the ability of light source to render colors compared to other incandescent reference sources. The manufacturers of the LEDs claim a CRO of 75 of higher for the phosphor converted and warm white devices in the LED industrial lighting market. Generally, a minimum CRI of 75 is needed for interior lighting.

CRI of 85 or higher shows excellent color rendering. CRI has been found not to be accurate for the RGB (red, green and blue) LED system due to the poor prediction of appearance quality of the saturated color objects. This may as well fail to correspond well to the human perception of color quality. Both CCT and CRI can only get you in the ballpark for matching and selecting lamp colors. There are several color rendering metrics which have been proposed over the last few years. For now, the color rendering of the LED luminaires are being evaluated for more information.

What is the difference between Efficacy and Efficiency 2017-05-11T11:50:31+00:00

Most people are not aware of the difference between efficacy and efficiency. The truth is that this two are not similar and here is the difference between the two.

Efficacy is usually expressed in lumens per watt while efficiency is expressed in terms of percentage of the LED efficiency. The efficiency of the light fixture is the ratio of the total lumens exiting to the total number of lumens that were initially produced by the light source. An example is that if a bare 100 watts incandescent bulb produced 1,000 lumens. If it is put into a fixture that gives 700 lumens, then its efficiency would be 70 percent.

Another difference is that efficacy is a term that is used where the input and output units differ. When it comes to lighting, one is interested with the amount of light in lumens produced by a particular amount of electricity in watts. Thus, efficacy is equal to the lumens per watt. Therefore, efficacy and efficiency are not similar.

 

GWC CORPORATION is Partnered with one of the largest manufacturing companies in LED lighting . By partnering with one of the largest LED companies in the world,  allows us to produce up to 16000 pcs per month, allowing us to take on any size project in Australia. On the same token this does not mean the standard drops. It allows as to create more revenue to put back into innovation and thousands of hours for testing, providing one of the highest standards in LED lighting.  We are not front runners  in the LED Lighting   YET , although the produces we sell are. We stand by the produces we sell 100%.We only want to create revenue if our quality is of the highest standard – reputation is our number one  Business goal. Partnering with  20 years experience will help uphold our number one goal.
