The brass & stainless steel models require that you to select the appropriate transformer for your needs. The Aqualux Telectran stainless steel models are designed to use our 12V-24Volt MultiVolt MR16 bulb options or you can supply your own.
The very popular plastic low voltageLED garden and pond/waterfeature lights are powered by a supplied 12V AC transformer. These 12V AC LED light kits have a cable that may be cut and extended with our low voltage cable to a maximum length of 15m before voltage drop may occur. This low voltage cable may be joined to be out of the water & spliced in by either an electrical cable connector or preferably with soldered connection.
