Short answer is no, they typically use 2 separate driver stages and output inductors, so you have to have a lamp in each side. Most use a single driver IC, which has 2 sdeparate stages in it, and which controls both lamps simultaneously, often providing separate EOL protection for each lamp as well, or on some a single lamp failure or disconnection will turn the other one off for ease of changing. Those also tend to lock out restart till power is cycled.
However almost all use a NXP driver, as they almost always follow the old Phillips layout and design for the circuitry, though more modern ones also include an active PFC stage as well, using a small 8 pin PFC and FET after the bridge rectifier, powered from the main SMPS chip.
