audioguru Well-Known Member Most Helpful Member Feb 8, 2009 #22 I haven't seen fireflies for about 47 years. My new white LED is still glowing brightly after 3 hours. Its top is sticking out of the case and feels quite warm but not hot. The top of the case is so hot that I can touch it for only a couple of seconds.
