This consists of a bimetallic strip which opens as it cools and in conjunction with the ballast inductor, provides the tube striking voltage. However, the random nature of the pulsing results in repeated striking attempts and degradation of both the tube and starter. The tube degradation is illustrated by its progressively blackening ends and ultimately required tube replacement. The Y1112L, “Fluoractor®”, has been specifically introduced for use in electronic starters. This unique device offers the lighting industry an opportunity to develop electronic starters small enough to be retrofit replacements for the established electromechanical canisters. Its double thyristor structure with integrated zener clamp diode and current mirror provides the technology for a starter with enhanced features such as controlled flicker free start up, automatic tube shutdown at end of tube life and reduced degradation of tube ends leading to extended life. The increased functionality, lifetime and reliability of these starters has led in some cases to them being embodied in the ballast itself, a development not feasible with the old electromechanical canisters.
