Low Voltage Safety Isolating Lighting Transformer

The Lumisphere® range of patented weatherproof low voltage lighting transformers have been designed especially for use with the Lumisphere® festoon system. The high quality of construction and combination of many unique features make it an ideal choice for most low voltage single or multi-light applications, especially for use in adverse environmental conditions. Lumisphere® transformers have been independently tested to IEC/EN 61558 – 2 – 6 – 2009
