But what about in practice?\u00a0<strong>Is it easy to choose the right lamp with so many options and brands?<\/strong>\u00a0Those who, back in 2014, took the lead and invested in LED lamps, believing them to be the solution to save money on lighting, may already be having to change them and encountering the same problem again. But that doesn&#039;t mean the LED was a hoax!\u00a0<strong>It was just the developing market<\/strong>.<\/p>\n<p>The good news is that<strong>\u00a0LED lamps were regulated in Brazil<\/strong>\u00a0for the\u00a0<a href=\"http:\/\/www.inmetro.gov.br\/\" target=\"_blank\" rel=\"noopener noreferrer\"><em><strong>Inmetro<\/strong><\/em><\/a>\u00a0for\u00a0<strong>offer more security to the consumer<\/strong>. The federal government published Ordinances Nos. 143, 144 and 389, which address the technical aspects of quality and the regulation of product marketing and certification.<\/p>\n<p>Both imported LED lamps and those manufactured in Brazil that were not in\u00a0<strong>compliance with technical standards and displaying the Inmetro seal on their packaging were prohibited<\/strong>. The ban on the sale of lamps without the seal by wholesalers and retailers came into effect on July 17, 2017 and, for micro-entrepreneurs, it will be valid on January 17, 2018. Therefore,\u00a0<strong>the consumer has to pay attention<\/strong>.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/selo-inmetro-eficiencia-led.png\" class=\"size-full wp-image-9996 alignleft lazyload\" alt=\"selo-inmetro-eficiencia-led\" width=\"188\" height=\"282\"><noscript><img decoding=\"async\" class=\"size-full wp-image-9996 alignleft\" src=\"https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/selo-inmetro-eficiencia-led.png\" alt=\"selo-inmetro-eficiencia-led\" width=\"188\" height=\"282\"><\/noscript>Look for this Inmetro seal on the lamp packaging, compare the information and follow the two steps below:<\/p>\n<p><strong><em>1) First step: understand the Inmetro seal<\/em><\/strong><\/p>\n<ul>\n<li><strong>Power (W):<\/strong>\u00a0how much energy the lamp will consume.<\/li>\n<li><strong>Luminous flux (lm):<\/strong>\u00a0amount of light that the lamp will emit.<\/li>\n<li><strong>Luminous efficiency (lm\/W):<\/strong>\u00a0amount of light emitted for each watt of energy consumed. What is expected from an efficient lamp is that it emits a lot of light and consumes little energy, so the more lm\/W, the better.<\/li>\n<\/ul>\n<p>In addition to the information contained in the Inmetro seal, attention should be paid to other equally important information.<\/p>\n<p><strong><em>2) Second step: learn how to choose the right lamp for your environment<\/em><\/strong><\/p>\n<ul>\n<li><strong>Color temperature (K):<\/strong>\u00a0light color, indicated as warm, soft, cold, daylight, etc. It typically ranges from bluish white (6,000 K) to yellow (2,700 K). At this time, you must be careful, as the LED light tends to be whiter than that of other lamps, so here is a tip: if you are looking for a warmer, yellow light, to give a cozy atmosphere to the room , turn it on and compare different brands of LED, even if they are all classified as \u201chot\u201d.<\/li>\n<li><strong>Color rendering index \u2013 IRC (%):<\/strong>\u00a0indicates whether or not the lamp will be faithful in representing colors. If you look at an apple in sunlight, you will see red. To see the same red under the light of a lamp, it must have IRC 100% (sunlight is the reference for this index). The lower the CRI, the more devalued the redness of your apple will be, that is, a lamp with a low CRI above a fruit counter, for example, can give the impression that the fruits are not as fresh. Normally, 80% is already considered a good IRC level.<\/li>\n<li><strong>Useful life (h):<\/strong>\u00a0is the number of hours that the lamp must last until the amount of light emitted considerably decreases. The useful life of a lamp depends on several factors, such as the conditions of the electrical installation, temperature and humidity to which it is subjected, the number of times it is activated by the switch, etc.<\/li>\n<li><strong>Supply voltage (V):<\/strong>\u00a0Be careful if you are buying a 110V or 220V lamp.<\/li>\n<li><strong>Guarantee:<\/strong>\u00a0Observe the warranty period and keep the invoice and product packaging.<\/li>\n<\/ul>\n<p>Now that you know the basics about LED lamps, it\u2019s time to understand a little more about the technology:<\/p>\n<p><strong><em>\u2013 LED can also be dimmable \u2013 look for the indication on the packaging.<\/em><\/strong><\/p>\n<p>Many LED lamps are already dimmable, which means that you can regulate the amount of light, leaving it almost off, for example, according to your wishes. You just need to have a suitable dimmer switch.<\/p>\n<p><em><strong>\u2013 Can LED lamps be disposed of in regular trash?<\/strong><\/em><\/p>\n<p>Unlike fluorescent lamps, which contain mercury in their composition, LED lamps do not contain any heavy metals, therefore they do not harm the environment. They could even be disposed of in common trash, but, as they are recyclable electronic equipment, the right thing to do is to send them for recycling in the same way we do with computers, cell phones and chargers.<\/p>\n<p><strong><em>\u2013 After all, is it worth paying more?<\/em><\/strong><\/p>\n<p>The cost\/benefit ratio of LED lamps is more advantageous compared to other lamps. However, for a more careful assessment, we must take into account some factors:<\/p>\n<ul>\n<li><strong>Initial investment:<\/strong>\u00a0How much more expensive is LED?<\/li>\n<li><strong>Energy cost:<\/strong>\u00a0LED consumes less energy, generating monthly savings.<\/li>\n<li><strong>Maintenance cost:<\/strong>\u00a0LED lifespan is longer, so you won&#039;t need to change bulbs as often.<\/li>\n<\/ul>\n<p><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/custo-beneficio-led.png\" data-srcset=\"https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/custo-beneficio-led.png 541w, https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/custo-beneficio-led-300x118.png 300w\" class=\"aligncenter size-full wp-image-9997 lazyload\" sizes=\"(max-width: 541px) 100vw, 541px\" alt=\"custo-beneficio-led\" width=\"541\" height=\"213\"><noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-9997\" src=\"https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/custo-beneficio-led.png\" sizes=\"(max-width: 541px) 100vw, 541px\" srcset=\"https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/custo-beneficio-led.png 541w, https:\/\/cebds.org\/wp-content\/uploads\/2023\/06\/custo-beneficio-led-300x118.png 300w\" alt=\"custo-beneficio-led\" width=\"541\" height=\"213\"><\/noscript>But this is all just the beginning!
