The lamp was only blackend for about an inch on each end, and replacing the caps restored the new brightness, which probably increased the lamps temp and likely evaporated the mercury again in an hour or so. That was 4 or 5 years ago, and I just this spring saw it go out with the trash, the tuner had died. And now he is being tested for lung cancer, haveing been diagnosed for advanced copd a year ago. A good neighbor, its painfull to watch him fade even faster than my wife. Who just interrupted my train of thought to request a BLT, but it will be minus the L, I'm have scared to buy whats out there anymore.
