Modern UV metal vapor lamps (the best UV lamps in the terrarium) require a so-called electronic ballast for operation. Without an electronic ballast, the UV lamp would not start at all. So why do you need this extra device?
There are two reasons:
1) As a starter for igniting the UV lamp: The electronic ballast sends a very high starting current of approx. 5000 volts into the UV lamp in order to ignite the gas mixture. The terrarium lamp ignites, the gas mixture heats up and after a few minutes full brightness is reached.
2) As a current limiter: During operation of the UV metal halid lamp, the discharge current increases and would destroy the lamp without electronic limitation.
