I’m not sure why one would run for an hour, tho? Isn’t it pretty much clap on clap off fast ?
Someone posted the times to me before but I forgot. Yeah - one video I saw where the guy experimented with Ecoli he zapped it for 30 seconds and it killed about half of them. (Left it in a petri dish for a day). At 2 minutes almost all of it was dead, 2 very small “colonies” each maybe the size of a millimeter.
I run mine for ten minutes, rearrange the items and then another 10 minutes. Two feet above the items, 25w bulb. Probably overkill - but....
