How to extend the lifespan of white color led gasoline price signs?

Here "18.7mA" is the maximum current the white DIP546 led lamp can work and the brightness is also the highest: 22000nits;

If you always let the white led lamps work under 18.7mA/12VDC, they will deteriorate fast and look terribly since the consistence is very bad;

 Here "18.7mA" is the maximum current and we leave space for you to adjust the electric current and the brightness of the leds. If we had set a related low point for running current, you will lose the chance to adjust the current and the brightness.

In order to increase the lifespan of the white DIP546 led lamps, there are two methods recommended:

(1) Most switching power supply has "adjustable" button inside, you can turn the 12VDC to 11.8VDC or 11.5VDC. Please experience it by yourself. When the inputting voltage of the power supply reduces, the electric current will reduce, too. As Voltage and Current all cut down, the led lamp lifespan will increase;

(2) Turn the High brightness into general brightness with your controlling software. This one is the main method to adjust the brightness. 10mA - 15mA is the ideal current for the white leds to work. For instance, at day time, the gas station needs the Led price sign show high brightness. It is OK. No problems. However, at night, since the environmental brightness is low, so the we can reduce the brightness of gas price sign can to extend the lifetime of  it and to save energy at the same time.

Now we can see the facts:

The led chips suppliers promise that their led chips can work 100000 hours(11 years) under half brightness( here it mean 12DC with 9-11mA electric current). Here your question and concept "continuous use" also depends on how you will make use of them. If you reduce "SOME" brightness that the gas station owner can bear, the white DIP546 led lamp can work for 2-5 years or more time without obvious deterioration. Our promise is TWO YEARS that the white led will not deteriorate obviously on condition that you do as we advise here.
