(The gist is in bold)
I recently got a PiGlow and started playing around with it. When I have the yellow LEDs set at > 200 for an extended amount of time, one of them starts to flicker and eventually goes out. It comes back eventually on a lower power setting, but it keeps going out with prolonged use at high settings.
I don't know the slightest about hardware and LEDs—so before I angrily ship it back to Amazon, I'm wondering if 1. these LEDs have an expected lifespan which is substantially below infinity, 2. I am misusing them in any way.
If no, should I just send it back and get a replacement? Is there anything I can do in the future to avoid this bummer? I really like my colorful swirly lights and am making cool patterns with them ^.^
edit: I should also allow for the possibility of something else being wrong with it, I guess, maybe on the raspberry pi level.
edit 2: I have not been able to reproduce the issue by simply turning on the yellow ones, or the particular one, only by turning most of the LEDs on to a high setting, after which no matter what I do, the yellow one at hand will start to flicker and turn off.
