Osram igniters are equipped with special anti-interference capacitors. At any time, they enable reliable, quick and lamp-protecting ignition. DEOS igniters are overcurrent igniters. The DEOS 172 is an overcurrent starter for series connections. DEOS ST 171, ST 172 and ST 173 igniters can work with both conventional and low-loss ballasts. They reliably switch off defective fluorescent lamps in inductive and capacitive operating modes. After pressing the red button, they are immediately ready to work. 4 times longer durability compared to standard ignitors. 18W, 20W, 22W, 24W
