Quite by accident I came across an advertisement for the sale of electronic ballasts for $7.5. Therefore, without thinking for a long time, I bought 4 such ballasts for replacement in garage fixtures. Since the buzzing of regular chokes was just starting to drive me crazy.
As you can see from the photo, they are capable of working with different types and wattage of lamps. The ignition is always stable. There is no flicker.
