What do the numbers of LED mean? such as 2835, 3528, 5630, 5050, and so on.

If you've ever bought or read about LED strip lights, you've probably been impressed by these numbers (models), 2835, 3825, 5630, 5050, etc. Actually, the meaning of these numbers is very simple.

Fundamentally, all of these numbers are the models of SMD (Surface Mounted Diode) LEDs, representing their sizes. Take SMD 2835 LED as an example, 2835 means its length and the width of the LED is 2.8mm and 3.5mm. SMD LED is a kind of semiconductor light source that directly mounted on the LED light strip, having characteristics of high brightness, low power consumption, and good workability.

Normally, the larger the sizes of the SMD LED, the higher the lumens and the better the heat dissipation. But, there also have exceptions. Let's compare the RU5050 LED strip and RU5630 LED strip these two LED flexible strip lights. Obviously, the RU5050's SMD 5050 LED light source is larger than the SMD 5630 LED of RU5630. However, in fact, the RU5630's brightness is higher than that of the RU5050, that is caused by the 5630's chip size is relatively bigger. But SMD 5050 LED has more excellent heat dissipation performance, which makes the LED light strip working more stable. Even the brightness of the same model of SMD LEDs may not be the same, which involves the materials, processes, and rated power.

You should know the meaning of these number of LED strip lights and their main differences by now. MLDR® is a professional LED light strip manufacturer in China, aiming to provide reliable LED lighting products to customers all over the world.

The difference between rope light vs strip light

In today's market, due to the product names haven't been standardized, the names of various LED light strips are a bit confusing. According to the input voltage, LED strip lights can be classified into high voltage LED strip lights and low voltage strip lights. Due to the high-volt LED strip are commonly sealed by protection tube, which makes it look like a rope so that LED Rope Light is its another well-known name. Therefore, in this post, we are actually talking about the difference between high and low voltage LED strip lights.

IP65 waterproof LED rope light

LED rope light i.e. high voltage LED light strip is a flexible LED light fixture directly driven by high voltage alternating current without the adaptor. The rope light is completely wrapped in the insulating sleeve, for its high working voltage is dangerous. Although it will result in the light strips' sizes increasing, it also improves their dust and water protection rating. In addition, the high voltage AC direct driving mode can save a lot of cost of power supplies, and let the LED strip can be connected longer length in series. In order to control the heat production, high voltage strips' power cannot be high as the low voltage strips, resulting in the relatively low brightness.

Low voltage LED strips are commonly driven by direct currents, such as 5V, 12V, 24V, etc, having really high safety and stability. The regular low-volt lights have no waterproof processing, their PCB direct expose in the air, which makes them have a good heat dissipation performance. Of course, they can also be manufactured to IP65, IP67, IP68 waterproof for outdoor use. Thanks to the excellent heat dissipating efficiency, low voltage LED strips can use higher power of SMD light sources and achieve higher brightness.

These are the main differences between the rope light and LED strip. MLDR ® is a LED lighting manufacturer, producing and selling all kinds of LED light strips.
