With the Econlux SolarStinger SunStrip T5 Holder it is possible to convert an existing T5 lighting system into the SolarStinger SunStrip LED lighting. After attaching the T5 Holder on the SunStrip, the SunStrip and the Holder are mounted like a fluorescent tube. Thus the aquarium cover can still be used. The T5 version is then only used as a passive holder (powerless). Additionally, there is the opportunity to turn the Econlux SolarStinger SunStrip in another position. For this, the small plastic cap, located on the bottom of the T5 Holders must be removed. After releasing the underlying screw, one can take the G5 socket off and bring it into the required position. In addition the screw is tightened and the plastic cap is put into ist place again.Delivery content Econlux SolarStinger SunStrip T5 Holder:2x T5 Holder2x Screw2x Nut
