Somehow despite the widespread usage of fluorescents in kitchens, places that are rife with kids underfoot, nobody ever considered the breakage of a tube there (and they each have more mercury than the screwbulbs do) to be an event worth anything more urgent than a good sweeping, vacuuming, and mopping — and that for the sake of the broken glass.
That’s why mine aren’t being replaced as they burn out, and will be swapped out for proper nontoxic pleasant-spectrum lighting when the last tube dies.
