LED Strip - Frequently Asked Questions ( The below information some comes from the Internet and professional websites.) *** What does different LED means? Like 5050, 3528, 2835, 5730 .... The abbreviation SMD refers to a 'Surface Mounted Device'. That means this is an LED Chip (device) mounted directly to a light strip, without using wires. The Numbers mean the dimension in unit milimeter. The LEDs are named by the dimension. For example, 5050 means the width and length be 50x50 mircometer. Different LED their spec. like brightness are different. Even the same code LED, their spec. are varied a lot. The LED maker and provide the same code LED in different levels. You cannot tell and compare the strip spec. by the same LED code, but need to look into the real data. Usually Supplier will specify the LED strip spec. accordingly. *** What LED chip are we use? The LEDs on our LED Strip are from by an established (1996) Manufacturer in Taiwan called Epistar. The LEDs have proved themselves to have a long lifetime and are of very high quality, a lifetime of at least 50,000 hours can be expected. Many of the cheaper LED Strips and Strips use LEDs which from the outside look identical to the Epistar LEDs but they are cheap copies with poor internal materials which give rise to a short lifespan. The LEDs on these cheap strips are usually mounted to a very thin circuit board with copper tracks which do not adequately dissipate the heat away from the LEDs further shortening the lifetime of the product. Most of these LED Strips are designed for short term use such as festival and holidays. The cheap LED Strips can also have LEDs which are poorly graded for color consistency so the color along the length of the same strip can look very uneven, for example some LEDs may appear a different white color to others which can look blue or warm white in color. For long term use and professional installation our LED Strip is a much wiser choice. *** What does CRI mean and why is CRI impor
