LM-79 was published by IESNA, which is Illuminating Engineering Society of North America. It is a recognised standard for industries to test their LED Products. This method of testing is performed to measure the electrical and optical properties of SSL products, also known as solid-state lighting products.
It is essential to get electrical products certified by LM-79 testing lab such as KC India Laboratories for several reasons. Firstly it helps to ensure the most important aspect, which is checking that the LED products meet with the required set of specifications. Secondly, it renders consumers the accurate information regarding the performance of the LED product. This helps them in making informed decision before they purchase the product. Thirdly, most of the government agencies as well as energy efficient programs require LM-79 testing.
Any accredited laboratory can perform LM-79 testing but one should note that all laboratories are not accredited. Thus before getting your products tested, check that the Laboratory is accredited or not. Laboratories should be accredited by a reputable organisation. NATA , National Association of Testing Authorities is one such well-known organisation. KC India Laboratories LLP is an LM-79 accredited laboratory.

Parameters Tested in LM-79 Testing
Mentioned below are some of the key parameters which are tested during LM-79 testing:
1. Luminous Flex: This is the measurement of the total light emitted by the product.
2. Luminous Efficacy: This is the ratio of luminous flux to the power of input.
3. Light intensity distribution: It is the spatial distribution of the light emitted by the product.
4. Colour Temperature: This is not a temperature but the perceived colour of the light emitted by the SSL.
5. Colour Rendering Index: CRI is the accuracy of the light emitted by the product in providing the colour of different objects.
6. The measurement of the input voltage and current
7. Power Factor
Any device that can process, store or transmit information is an IT product. Some examples of IT products are computers, laptops, tablets, smartphones, software and networking equipment.
IT Product Testing
IT product testing lab performs the procedure of evaluating performance, functionality as well as the security of the product. It is essential for a number of reasons. Firstly it helps to ensure that the product meets the performance specifications. Secondly, it is greatly beneficial for identifying and fixing any defect or bug before the product is released in the market. Thirdly, it also helps to ensure that IT products are secure from cyber-attacks.
