DC voltage operation (during emergency back-up)
Because of the run up, T5 VHO and HO Extreme Temperature lamps (and therefore ballast) are not suitable in combination with emergency situations.
4.5. Switching cycle effects
The rated average lamp life of T5 lamps is negatively affected when the switching frequency is higher than the IEC cycle (3 hrs cycle: 2 hours and 45 minutes on, 15 minutes off).
