HFR239TL5EII is an Electronic Regulating Ballast with flat lightweight high-frequency using 1 to 10V protocol for TL5 fluorescent lamp. The lamp power can be dimmed from 1 to 100% via the analogue control input, compliant with European and Asian norms and suitable for emergency lighting systems, HF operation improves light quality, lamp lifetime and combined with controls, additional energy savings can be achieved. It features programmed start flicker-free ignition <0.5 seconds and striation-free operation, no stroboscopic effects, preheating the lamp electrodes enables the lamps to be switched ON and OFF without reducing life, smart power ensures constant light. It offers independent of mains fluctuations, up to 60% reduction in energy consumption by using automatic lighting control systems, stop circuit is activated within 5 seconds in the event of lamp failure (safety stop) and ballast resets automatically after lamp replacement.
