Ericson’s handlamps meet OSHA regulations and create a safer working environment. This Low Voltage hand lamp offers step-down transformers which reduces a 120VAC line voltage to 12VAC. The extra-thick walled rubber housing with non-corrosive stainless steel hardware protects transformer from jobsite contaminants. The transformers themselves incorporate a grounded metal shield between primary and secondary windings to ensure the two voltages are isolated providing an added degree of protection. Each transformer is subjected to a factory dielectric test of 1600 volts between primary and secondary windings and between each winding and ground to ensure safety. And with the high-visibility dual-color safety system, identification of these special-use lights on the jobsite is easy!
