Seems to be a lot of variation in recommendations. Philips and GE claim at
least some of their bulbs don't require burn-in

While Osram suggests 100 hours, not just 12 to 24

But I couldn't find anything to suggest that light output rises after
burn-in; in fact it drops somewhat from "initial" lumens to "design" lumens.
It also applies only to bulbs that will be dimmed, which I doubt Inch is
planning to do.
