Hurry up, only 6 items left in stock.
The KAOYI KT10521 Electronic Transformer 105W is a compact LV halogen transformer 230V to 11.4V, ideal for powering 12V halogen lamps (low voltage) in recessed lights, spots, and many lamp housings. Thanks to its particularly small housing, the electronic halogen transformer also fits into tight ceiling areas or existing transformer compartments and is suitable as a replacement transformer 105W for many identical models from other manufacturers (compare technical specifications).
Thanks to soft start, lamp life is extended, and additionally, overload and short-circuit protection with auto-reset ensure safe operation.
