The Lamp Clamp is the right choice for a safe and reliable lamp holder for your sink. The heat resistant ceramic socket with E27 thread is suitable for all standard incandescent, fluorescent and UV lamps. The sturdy aluminum lampshade is equipped on the inside with a highly reflective coating for the best possible effect when lighting your aquarium. With the included mounting clip and 360-degree rotatable ball joint, the clip-on light can be mounted to one side of the sink in a targeted manner to optimally illuminate the sink. Mounting brackets on the mounting clip ensure a secure fit. With the help of the switch, the clamp lamp can be easily turned on and off. Alternatively, a timer switch such as the HOBBY Terra Timer pro (Item No: 36155) can be used for automatic control. With a clip-on lamp guard available as an optional extra, terrarium residents are guaranteed the highest level of protection against burns.
