Not all LEDs are the same quality, as much as some people try to sell that point. There are different grade led chips. Lower cost chips, not as bright. One way to compensate is a trick called "overdriving". This will allow a higher voltage to the led making it brighter, for a shorter time. So when its new, looks great. So if your a flipper, these are the LEDs for you. Someone else's problem when they dim out.

Another thing is packaging. This is the other components that provide the power to the leds. Higher quality, better tolerances! Same as leds there are different quality resistors. Low quality, low life expectancy. If the resistor values vary a larger amount, you will have more failures, more dimming, and shorter life.

Sorry to hear about the experience with the picture of the led with two months use and it now worthless. Unfortunately we hear the same story every week.

As with most products available, they are not all the same. As a route operator I have a lot of experience with LEDs with many hours on them. More then glad to chat about the amusement business, pinball, and leds.
