The White Python 30cm Power Cable is exactly what you need to power up your LED Lighting Kit efficiently, but don't need a long stretch of distance to cross.
If you purchase individual WhitePython LED light strips, you will need to purchase an LED Power Cable which fits in between your Power Supply and Light Strip. Available in 2 lengths, the 30cm Power Cable comes as standard in all LED light kits.
However, the 1m Power cable is ideal for those who need a further reach. Also, combined with the Aux to Female Extension cable, this can create a long extension in-between 2 light strips (perhaps reaching across 2 terrariums).
