![]() ![]() They are the least bright and least power-intensive of the three chips we use at HitLights, and are most commonly used for accent lighting, such as above kitchen cabinets and around the crown molding below the ceiling.ģ528 chips used to be featured in our Luma5 strips, but those now primarily use lower output 2835 chips which offer the same brightness of 3528 chips but with greatly improved efficiency and lifespan. SMD 3528 Chips are perhaps the most common of all LED light strip chips. Note that size is not proportional to output or performance, and it is not the only difference between LED chip types. Take SMD 3528 for example, they are 3.5mm wide and 2.8mm long. The numbers after the SMD simply refer to the physical size of the LED Chip. This surface mounting technology is indeed what makes LED Light Strips possible. That means this is an LED Chip (device) mounted directly to a light strip, without using wires. The abbreviation SMD refers to a 'Surface Mounted Device'. These numbers are less mysterious than you might think.įirst off, you might have seen the letters "SMD" preceding these enigmatic numbers. Changing from 4000K to 5000K will typically only increase brightness by 20-60lm, in the same fixture, of course.Have you ever been looking for LED light strips and ran across the numbers 2835, 3825, or 5050? While a 2700K bulb will cast a cozy, orange glow and a 6000K bulb will emit a crisp, blue light, the brightness will nearly be the same. Good question! Lighting color, or light temperature, is measured in Kelvin (K). The average LED light temperatures range from 2700K (warmest) to 6000K (coolest). How does color temperature affect brightness? ![]() ![]() So as a rule of thumb, high output LEDs have an efficacy of 100lm/w or more while some commercial LED lights, such as LED Tubes, can feature efficacies of over 130lm/w. As an example, a LED Flood Light with 10,000lm and 100W has an efficacy of 100lm/w. This can easily be calculated by dividing the lumens/watt. Efficacy is essentially, how you could measure the “bang for your buck” when it comes to the brightness you are looking to achieve. For a mental image, a standard 16W A21 LED Bulb is an ideal replacement to an 100W incandescent bulb, and will be as bright, If not brighter!Īnother common measurement you might notice on specification sheets for LED lights is efficacy! And no, this is not the same as efficiency, which refers to the amount of energy used. Also, when you provide power to an LED light, more energy is converted to light rather than heat which is why you will often see wattage equivalency listed on the specifications for LED lights. Created by design, the LED light has a minimal heat output, which would place them as less hazardous and allow construction of the bulbs to include shatterproof materials. Without a good knowledge of lumens, it could be safe to assume that an LED having fewer watts would be less bright than a traditional bulb that has higher wattages however, that is most certainly not the case! As previously mentioned above, a LED light requires way less energy to operate and produce the same, if not more light than a traditional bulb. Why are LEDs brighter with less wattage you ask? To put this into perspective, a standard household LED Bulb has an average lumen 800lm, while a large commercial fixture, such LED Shoe Boxes or Stadium Lights, can reach 160,000lm per fixture! What are lumens? Glad you asked! Lumens (lm) are a measurement of light output! This would mean that the higher the lumens, the higher the brightness of LED lights is going to appear. Although we all know LED lights are a brighter replacement for fluorescent, incandescent, and halogen bulbs, and they require far fewer watts to produce that brighter light, we measure the brightness of LED lights in lumens. In traditional lighting knowledge, wattage is the standard measure of brightness for most, with higher wattage portraying a brighter bulb.
