Current ripple

To ensure long lamp life, current ripple must be as low as technically possible. The quality of the direct current used to operate the lamp is of utmost importance – it is specified as a percentage. Ripple is one of the most critical elements that contributes to reduced lamp life and should be less than 10% peak to peak for xenon lamps up to 3000 watts, and less than 5% peak to peak for lamps over 3000 watts. Monitoring and measuring current ripple can avert reduced lamp life due to excessive ripple.
