Eaton Convertalite Emergency Conversion Kit for TC-L compact florescent lamp delivers optimum performance for a diverse choice of fluorescent lamp types and wattages. Each module has 4 pole output switching plus an additional relay pole to isolate the switched live in emergency mode. Consequently, lock-out of the ballast is prevented when it returns to mains mode. Low profile modules and unique chamfered battery end caps, easing integration into shallow luminaires, are standard throughout.
