8/12/2023 0 Comments Led black light strips wired up dc![]() Luminosity doesn’t always tell the full story. ![]() If you oversize your LEDs a bit from the beginning, you will have some extra brightness to make up the difference as they age. Using a dimmer will lower the operating temperature of the LEDs which will lengthen their lifespan.įurthermore, as LEDs age, they do lose some of their luminosity. Then, get a dimmer to reduce the brightness to the desired level. It’s a good idea to buy strips with extra brightness for your application. Here are some guidelines for choosing a brightness level depending on the situation. For LED strips, the question you are interested in is, how bright is my strip per unit length? So rather than a total lumen amount, you should be looking for lumens/foot or lumens/meter. What are the differences between cheap and expensive? And, what is best for your project? Brightnessīrightness or luminosity is usually measured in lumens. There are seemingly endless variations of LED strips that are being sold in a wide price range. ![]() In practice, the bigger gap can make the light less uniform. The distance between each similarly colored LED is greater on the RGB+CCT strip compared to the RGBCCT strip. One creates colors and one creates whites. Each chip can create colors and whites.Ĭompare that with an RGB+CCT strip. The same chip is used continuously throughout the strip. This can allow for a better spacing for multi-purpose (color-changing) strips.įor example, an RGBCCT chip has 5 total diodes on one chip. A large chip can potentially fit multiple diodes on the same chip. A narrow chip can be mounted to the strip more closely together creating a more uniform light.Ģ. Size does play a role in determining how many LEDs can be mounted on a strip:ġ. Also, it manages to put out more light while still using the same amount of power (more efficient). ![]() Notice how the 5630 puts out more light than the 5054 even though it has less surface area. Ultimately, several factors determine the overall brightness including the chip circuit design, power consumed, and materials used.įor example, below is a table with basic specifications for three different chips made by Epistar (a popular LED manufacturer). Generally a larger chip is brighter, but not necessarily. Therefore, there’s no guarantee that chips of the same size from different manufacturers have similar performance. Source Common addressable LED controllers:Īlthough most equal sized chips have similar characteristics, not all chip manufacturers are created equal. Instead, the number is the name of the integrated LED controller chip. But in this case, it has nothing to do with chip size. If you are looking at a digitally addressable strip, you will likely see a four digit number (for example, WS2812B or SK6812). Similarly, a 2835 chip measures 2.8 mm wide by 3.5 mm tall. The number usually describes the size of the chip.įor example, a 5050 LED chip measures 5.0 mm wide by 5.0 mm tall. One 3 channel chip with RGB LEDs and a separate 2 channel chip with cold white and warm white LEDsĪ single 5 channel chip with RGB, CW, and WW LEDsĪn LED strip description often includes a 4-digit number such as 5050 or 2835. One 3 channel chip with RGB LEDs and a separate single channel chip with white LED Examples of common LED chip configurations: LabelĪ single 4 channel chip with RGB and white LEDs The CCT LEDs can either be both on the same chip or on separate chips. By adjusting the power delivered to each white channel, the strip can produce any white light equal to or in between the two LEDs. One is a warm white and the other is a cool white. Warm white is usually 2700K, similar to the color of an incandescent bulb.Ĭold white is in the 6500K range, but check to be sure.ĬCT usually means that the strip includes two channels of white. There’s no set standard so make sure to double check. Typically a single “W” refers to a pure white (6500K). By adjusting the power delivered to each color (using a controller), any combination of colors can be created. When the LEDs are on separate chips, fewer lights can be packed into the same length strip.Īn RGB LED contains three diodes (LED stands for Light Emitting Diode) on the same chip: one for each color. If there is no space, it usually means they are all integrated into one chip. If the letters are separated by a “+” or a space, it usually means that they are separate chips. The letters in the description refer to the output color(s) of the LED chips on the strip. If you’re shopping for LED light strips, you’re likely to come across all kinds of letter and number combinations that are supposed to describe the strip you’re looking at.
