OSRAM SubstiTUBE T9 LED is recommended as a direct alternative to conventional 22 W and 32 W T9 fluorescent lamps. No rewiring is needed, thanks to CCG compatibility. SubstTUBE T9 comes with a replacement starter, making the replacement safe and preventing electric shocks even if the traditional starter is removed. High efficiency of 100 lm/W provides energy savings of up to 45% compared to traditional T9 lamps.
