There are two reasons: maintaining the power operation of 80% of the Led strip can greatly increase the service life of the led chips; in addition, in order to better improve the luminous efficiency, the thermal energy is converted into light energy to the greatest extent. When the flexible Led strips reaches 24W per meter, its heat dissipation problem must be considered. The usual way to dissipate heat is to stick blue adhesive on the back of the Led strips and stick it to the aluminum profiles to help dissipate heat.

When we calculate the theoretical power, we only need to know the power of a single led chip and then multiply it by the number of led chips.

Taking 5050 SMD 60pcs Led strip per meter as a example, the power per meter is 14.4W, 5050 SMD single chip power 0.24W x number of SMD, 60LEDs= 14.4W/M; conventional 3528 SMD power is 0.08W, 2835 SMD The power is 0.1W or 0.2W, and other led chip models are: 3014, 5630, etc.

In theory, the higher the wattage, the brighter the Led strip will be. But brightness isn’t just determined by wattage, and it can’t be determined by wattage alone. So what are the other factors that determine brightness? The brightness is also related to the number of led chips per meter, the display index, the size of the led chip, and the color temperature. Therefore, the wattage is not the only determinant of brightness. On the contrary, the wattage of the Led strip should not exceed the normal wattage. As mentioned earlier, the wattage is too high and the heat dissipation is not good, which will affect the service life of the Led strip.

Customers often ask us whether Led strip can achieve 39W or 48W. In fact, there are many ways to improve the brightness. In addition to environmental protection, the biggest advantage of LED is: energy saving. There is really no need for us to increase the wattage of products that were originally energy-saving and become inefficient. At present, our company has made a high-brightness Led strip. The luminous efficiency of the normal Led strip is: 100-110LM/W, our product can achieve 160-170LM/W. The following is his test report, its luminous efficiency The efficiency is 172.6LM/W :

That is to say, in a Led strip with a normal brightness of 100-110LM/W, the brightness of 28W is: 28W x 100LM = 2800LM, but if we use our high-brightness Led strip, 172LM/W, as long as 2800LM / 172LM = about 16W can be realized. It truly achieves high brightness, energy saving and long service life. If you need more information, please contact us.

In fact, the wattage alone is not enough to quote. Take the 7.2W Led strip as a comparison, customers generally have the following options:

3528SMD 120led per meter

2835SMD 60led per meter

5050SMD 30led per meter

It is not difficult to see from here that different led chip models and different quantities can make the same wattage. Among them, the highest price is: 3528SMD 120 leds per meter, the most cost-effective is: 2835SMD 60 leds per meter, and their brightness is similar, 2835SMD 60leds per meter will be a little brighter.

You can consult our professional sales team for assistance. Selecting the right LED driver depends on several factors:

1. Total Power of the LED Strips: Ensure the driver's capacity meets or exceeds the combined wattage of all connected LED strips.
2. Wiring Configuration: Consider the setup and layout of your project to determine the driver's voltage and connection type.
3. Application Environment: Determine whether the driver will be used indoors or outdoors, and if it requires waterproofing or other specific features.
