Size of LED:
Subtle light – Ideal for most domestic situations for task or ambient lighting where observers are close. Such as ceiling coves, under-cabinets, on stairs and around windows
Bright light – Ideal for commercial or domestic use where the observer may be further away – Like high ceilings, used as a wall washer, outdoor lighting, ambient lighting for larger areas. 5050s can also be used for colour-changing RGB or RGBW LED tape.
Much more smaller and thinner than 5050, 5730 and 3528, you can view 2835 SMDs as a more efficient replacement for the 5050 – producing 20% more light in same power consumption.
Basically a stretched 5050 LED with a much wider viewing angle. The wider angle makes it easy to emit a brighter output with the same wattage
New innovation, much smaller and thinner than 3528 SMD LED, high density led available such as 300led/m or 420led/m, to achieve best even light without led dot.
