Until relatively recently there was no such thing as a commercially available ultraviolet (UV) LED light. But as LED technology continues to develop and power densities increase, UV LED lights are expanding into the market and replacing more traditional alternatives. Ultraviolet (UV) light is an invisible form of electromagnetic energy (light energy) that travels at a higher frequency and carries more energy than visible light. UV lightwaves were originally called “chemical rays” when first discovered in the 19th century because of their ability to cause certain substances to change at the molecular level. Here are a few examples of the many applications for UV LED lighting:   Industrial and Cosmetic Curing UV curing is a process that uses UV light to instantly cure (or “dry”) inks, coating and adhesives through cross-polymerization of photosensitive materials. UV LED technology is emerging as an ozone gas- and mercury-free option for chemical curing with both industrial and cosmetic applications. Nail polish cures have traditionally been done using unregulated UV lamps, but controversy arose earlier this year over a study published in the Journal of the American Academy of Dermatology which reported a potential danger of skin cancer. The study found that LED lamps were much safer for this application, due to the lower frequency of UV light they emit. Analytic Tools Due to UV lighting’s ability to make certain materials visible to the human eye, it has been used for quite some time as an analytic tool. One common use for ultraviolet light sources is checking UV watermarks to validate currency, or identifying bodily fluids in forensic crime scenes. Scientific and Biological A 2012 study published in Applied Entomology and Zoology showed that UV LED lights were an effective method for dealing with the West Indian sweet potato weevil. This disagreeable insect...

When shopping for LED strip lights, you’ll regularly come across numbered terms such as 3020, 3528, and 5050. So what do these numbers mean, and why are they important in your buying process? This simple explanation will help you in understanding the different numbers used in LED strip lights. First, a basic understanding of how the strips themselves are constructed. The LED chips are mounted onto a thin, flexible metal strip that acts as a heat sink, drawing heat from the light chips and allowing them to remain cool during operation. This construction accounts for the “SMD” you’ll often see in strip light specifications, which stands for Surface Mount Device. The four-digit designation refers to the dimensions of the chip itself, in millimeters. A 3528 chip, for example, measures 3.5mm by 2.8mm, while a 5050 chip is 5.0mm by 5.0mm square. These different sizes dictate how many chips can be placed on a strip, which in turn determines its particular light qualities. Each has its benefits, so let’s break them down one at a time. The 5050 chips that Flexfire LEDs uses are actually composed of 3 light diodes, a construction sometimes referred to as a tri-chip. With 3 diodes, a 5050 chip will be brighter than other chips with one individual diode. But while a tri-chip is theoretically three times brighter, their larger size means fewer of them will fit onto a strip’s PCB (Printed Circuit Board). It also means they will generate more heat, requiring a thicker PCB to act as a heat sink. Finally, a tri-chip can be constructed with different types of diodes in the same chip, generating unique visual results. The three diodes can be combined to create millions of different color combinations, making them an excellent choice for...

Under cabinet lighting is one of the most common applications of LED strip lights. This relatively easy installation is a fantastic addition to any kitchen, office, or work bench area that would benefit from high quality direct task lighting. To illustrate this installation, we’ve put together this step-by-step tutorial on how to install under cabinet LED strip lighting. For this tutorial, we reached out to a customer named Owen in Toronto, Canada. Owen was seeking bright, usable light in his kitchen that could be hard-wired to a standard wall dimmer, and told us he had been, “scouring the web off and on for three years” in search of the perfect solution. In the end, he chose Flexfire LEDs UltraBright LED strip lights in natural white after viewing some of our online installation videos and feeling comfortable with our product quality. It’s important to note that for this installation, Owen enlisted the help of a licensed professional electrician. This is something we recommend for all installations, as it ensures code compliance and avoids potential injuries due to improper handling. Here is a “before” photo of his kitchen, using only the existing overhead lighting. And now, onto the installation! In order to achieve proper brightness and even light distribution, he used our solderless connectors to run two parallel sections of LED strip lights under each of three cabinet sections. In the end, he felt that one single strip would have been more than enough, and this parallel run wasn’t actually necessary. Also, note that the strip lights are very thin and low profile – the strips themselves are only actually visible when viewed from below as photographed here. As Owen says, “The low profile design means I don’t even have to rush to add a valence.”...

CRI, or Color Rendering Index, is the latest buzzword in consumer lighting circles. With the current phasing out of traditional incandescent bulbs, many consumers are scrambling to understand their remaining choices. Savvy lighting manufacturers understand this, and have invested a great deal in educating customers about things like color temperature, lumens, and now CRI. So how does CRI work? Basically, take a light bulb and shine it onto a few bright, colorful items. How natural do their colors look? Color Rendering Index is a mathematical measure of this, where a light source is tested and given a score from 0-100. Any light bulb, tube, or strip that measures greater than 90 is typically considered “High CRI”, and thus very effective at rendering natural-looking color at a given color temperature. As a point of reference, many of the fluorescent or other types of lighting that people consider “harsh” or “artificial” measure in the 50-70 CRI range.   Take a look at the two photos above. In the first photo, under lights rated at CRI 57, the orange bell pepper has lost much of its natural color, appearing almost yellow. Similarly, the green apple, red bell pepper, and yellow marker appear dull and lifeless. In the second photo, under CRI 93 lighting, the colors are much more alive in comparison, down to the white board on which everything is placed. Testing for CRI requires special machinery designed specifically for this purpose. During this test, a lamp is shone onto eight different colors (or “R values”), termed R1 through R8. The lamp receives a score from 0-100 for each color, based on how natural the color is rendered in comparison with how the color looks under a “perfect” or “reference” light source at the same color temperature...
