Subtle light, ideal for task or ambient lighting in small areas, such as ceiling coves, under cabinets, on stairs, and around windows.
Bright light, ideal for commercial or domestic use over larger areas or longer distances, like high ceilings, outdoor lighting, and wall washes. These also work for color-changing RGB or RGBW LED strips.
Much smaller and thinner than 5050s, consider 2835 SMDs an efficient replacement for the 5050, producing 20% more light with the same power consumption.
Basically a stretched 5050 with a wider viewing angle. The wider angle makes it easier to emit a brighter output with the same wattage.
Smaller and thinner than 3528s, you can get these in 300 LED/m or 420 LED/m, to achieve the best even light without LED dots.
