Many of the explosion proof lights we manufacture are what are known as “hand lamps,” or “drop lights,” meaning worklights that are small enough for a single worker to carry or hang as a light source. These explosion proof hand lamps are available in traditional single-cord plug-in models as well as with inline transformers. An inline transformer allows the “stepping down” of higher voltage from a source outside of a hazardous area to a lower voltage for use within the area.
