Gas Price Sign Numbers Are Made from 18 inches White Color Led Digit Segment
1. Do your white color digital led gas price signs also deteriorate after a while?
Reply: Any white color led digital gas price signs will deteriorate after sometime. It also takes place in our 18” led Digital Gas Price Displays. Even you choose Nichia from Japan, Cree from America and Osram from German (their DIP546 led lamps will be much expensive to purchase), the white leds will deteriorate, too. Our DIP546 led lamp has larger size led chips encapsulated inside with small electric current, they will work better than the bad white leds you have seen in Mexico.
Here “a little better" means "obviously better"; it does not mean "much better"; I hope you can understand it.
2. How many hours of continuous use with your white color gas station led price signs before deteriorating?
Reply: Generally speaking, it is very hard to tell you an accurate time. This time the electric current we designed for the white leds is 18.7mA/12VDC, please see the following graphics: The following graphics show the "series electric circuit" we designed for you:
3. Led color: white;
