The Bright Control EVO is a low-budget electronic ballast for the operation of the Bright Sun. It does not provide advanced features, like the Bright Control PRO series with its intelligent chip control system that ensures a longer life and more stable spectrum of the bulb but in regards to performance and safety it blends in with the market standard. Consequently the Bright Control EVO is our price-recommendation while the Bright Control PRO series is our clear overall recommendation for use with the Bright Sun due to its flexibility, efficiency and longevity . Attention! Supplied with open cable ends on the ignition cable. No plug and play connector!
