Both are relevant, and can feed into each other. A incandescent lightbulb that has been on for a long time is more likely to fail after a power cycle, as the cycling adds additional stress (anyone who's used them can attest to this: the most common experience with one failing is going to turn it on, only to get a brief flash of light before it fails).
- pfdietz 3y agoSure. But that has very little to do with lifespan.
- rcxdude 3y agoIt seems to be relevant to lifetime, though not the dominant factor in most cases. There is an annoying shortage of actual data on this online though (the best actual experiment I can find is mythbusters where a 2-minute on-off cycle caused a failure in two weeks, which is obviously extreme but shows how rapid cycling can affect lifespan).
