The fourth generation of electronic ballasts for scientific/technical applications of mercury, xenon, and mixed gas discharge lamps up to 75 watts. 

The highly stable DC current supply with low residual ripple guarantees constant, flicker-free light output. Glow
discharges are effectively avoided through permanent, fast monitoring of the lamp current and voltage.

Like all electronic ballasts from LEJ, Series 04 is also equipped with a safety circuit function and a resettable lamp operating hours meter.
