Increases the broken light spark cooldown 6 folds (tgstation#54579)

Whenever you stop to do something, and there's a broken light around, you would notice it spark, and if you stay, it sparks over and over again, becoming less of a nice rare occurance to something more annoying. This was very apparent during a shift yesterday on Manuel, where the entire station had lights broken, but they kept sparking over and over again and it never quite felt like we're in darkness.
