Also the fact that it's been on continuously. Incandescent light bulbs seldom burn out while they are on, unless dropped or hit. Failures are caused by the current surge when it's turned on. However they must have had power failures during the many years the bulb has been there. I wonder how they protect it from surges when the power comes back on. |
