Tru-Core™ Technology

Unique Lighting Systems’ highest commitment is to set the standard for manufacturing, innovation and quality products. All Unique™ transformers up to 1120 watts are Tru-Core™ designed transformers. Tru-Core™ Transformers are engineered and built by Unique with solid copper core windings and the highest quality materials.

Our high quality materials and precision grain-oriented steel laminations combine for an energy efficient product with very low no-load amps. We utilize dual layer insulation between the primary and secondary winding. As an industry leader we wind our own cores and specify all the materials including laminations, copper wire, surface area of the wire and more. You can buy a less expensive transformer, but you can only get the quality of a Tru-Core™ from Unique Lighting Systems®.
