Sylvania BR30 Bulbs unavailable--wiring GE Switch to bypass load?

Sylvania makes a battery powered smart switch cover you can put on the wall right over the existing switch. You leave the existing switch on power and you can use the buttons on smart switch to turn the group of lights on and off without actually cutting power to them. So no wiring, it’s very simple, it works well. So it’s worth considering.
