Two things...
1. They could be bothered by the light and come out at night.
2. Had some hives at some land that ended up having a couple of underbrush burns definitely farther away than yours. Smoke was present throughout the property. Don't know if it was the cause, but those hives just did not produce honey that spring/summer. Meanwhile, hives 5 miles away pumped it out.
If it were me, I'd pass on the bonfire near my hives.
