Advanced:
1.consumes 50% less power than conventional MB and does not require extra power equipments such as transformer, etc.; thus total investment is reduced when compared to using traditional MB.
2.contains automatic full-function protection circuit using pulse soft start and modulating frequency. When open or short circuit occurs, the self-protection circuit will be active automatically shutting down the output of the EB. The built-in adaptive control system guarantees EB to work efficiently and reliably with either MH lamp’s or HPS lamp’s discharge characteristics from different manufacturers, old and new. This system can automatically and perfectly adapt to different lamp characteristics preventing lamp cathode being impacted from rush current, thus reaching high luminous efficacy and extending lamp’s life.
3.Low operating temperature and longer life: low operating temperature is an important factor for electronics. EB’s temperature rising is less than 25°C(in example, if ambient temperature is 30°C,operating temperature is 55°C).Because AR/EB is able to maintain low operating temperature, its operation life is extended.
4.No flickering (eyes protected) , no noise.
5.Simple yet sleek design: small size and light weight.
6.Voltage fluctuation and full-functional protection, stable output power to lamp.
7.Soft startup and advance lighting quality.
8.Absent acoustic resonance and smooth lamp operation
