What percentage of consumers are familiar with it?
What are the specifications and features of the best and highest quality LED light or panel, 60*60 or any other size?
1- A quality 60X60 lamp or 60X60 LED panel that can last for at least 5 and at most 10 years with a daily operating time of 8 to 12 hours must be made of an aluminum or metal body that can dissipate the heat of the SMDs. And if the panel is small, it must have a suitable heat sink in addition to a metal body.
Because in small lights and panels that are usually used for local lighting. For this reason, due to the high density of LEDs, more heat is generated, as a result of which the work of the heat sink in these types of panels is to transfer the heat as best as possible to the outside of the interior of the light. Therefore, a stronger heat sink should have more and longer fins so that firstly, the temperature in the SMDs increases less and the heat of the aluminum module, which is created due to the high density of SMDs, accelerates the transfer of the temperature inside the panel to the outside environment.
2 - The wattage of a lamp or LED panel does not alone indicate the desired light. For example, it can never be said that a 10-watt lamp is brighter than a 7-watt lamp. We need to know what the lumen per watt (its light output) is.
Unless the product has a standard mark and its lumens per watt per watt of consumption is claimed by the manufacturer to be at the highest level of similar products and these claims are reliable for you. This trust can only be recognized based on the past records of a manufacturing company, or both products are manufactured by the same company with the same conditions and form of manufacture and the same raw materials are used, and its lumens per watt or luminous flux is also specified. Unfortunately, some brands have abused public trust and sometimes what is registered as specifications on the product is completely inconsistent, to the extent that in a 660 product model with Milad Noor, there is an 80% excess consumption only in its consumption section.
For example: Miladnor Industrial and Manufacturing Company produces 50-watt LED panels or lights in dimensions of 60*60 with 6000 lumens of output luminous flux and proudly sells them with the Iranian National Standard mark on the product. But most of the panels available in the market either do not mention the lumen amount and only mention the wattage or use the word "excellent light". And if the lumen amount is mentioned, respected consumers should pay attention to its standard mark and then compare the lumen output and wattage.
The modules used in the 60*60 lamps and all products of Milad Noor Lighting Industries are selected from the highest quality LEDs (SMD) with the latest technology, which is why its high-quality type has a long lifespan. It is necessary to inform you that Milad Noor Lighting Industries Company, with a history of more than 44 years of activity, cannot question its reputation and use low-quality raw materials because of some people like builders and sellers who only pay attention to the price of the product and do not care about quality at all.
3- A quality LED light or panel, if it is in an environment below 35 degrees Celsius, should have a lifespan of 50,000 hours, or 5 years, of continuous lighting, and after 3 years, it should be 90% of its original brightness. And if it is lit for 8 to 12 hours a day, this light should have a lifespan of more than 10 years, while most products on the market have a warranty of between one and two years.
4-Flicker, in simple terms, refers to rapid changes in the blinking of a lighting system source that can be detected visually or non-visually, depending on its frequency and the nervous system of individuals. Flicker that is perceptible to the human eye can create an uncomfortable sensation for the viewer.
5- Total Harmonic Distortion or THDI-V:
One of the quality parameters in electrical equipment is that consumers or loads in the power grid unintentionally generate these harmonics due to certain reasons. Here we mean total harmonic distortion (THDI). High current harmonic distortions cause the following negative effects in electrical equipment:
5-1-Heat generation
5-2-Destruction of insulation
5-3-Negative effect on circuit connections
5-4-Improper performance of power network equipment and energy loss Electronic distortion is shown as a percentage, and the lower this parameter is, the better the quality of the product. The National Standards Organization of Iran has considered the presence of different percentages of this quality parameter in lighting products as a special requirement for obtaining a quality and performance standard for the product.
5-5- The THDI percentage in quality lighting products is best in the range of 5 to 20. Using PFC harmonic filters in the product driver circuit can help improve this parameter. In Milad Noor products, for lighting of 50 watts and above, this number is less than 10. The maximum acceptable harmonic distortion for an LED product is 200.
1- The lumen output is greater than 110, and the higher this number, the more desirable, provided that the decrease in its value after one year is less than 10%.
2- The power factor (PF) should be close to one. For example, Milad Noor products for 50-watt and more than 50-watt 60*60 lamps are more than 98%.
3- THD in a quality lamp should be less than 20. For example, in Milad Noor products, in 60*60 lamps and all lamps over 50 watts, and even many 16, 24 and 32 watt lamps, this number is less than 10. And unfortunately, in poor quality lamps, it is about 130. For the differences explained, be sure to refer to the table below.
