The QL lamp system uses a revolutionary technology of light generation that combines the principles of induction and gas discharge using an A-lamp design. It is comprised of a generator, the power coupler and lamp having no electrode.
An induction coil powered by an electronic unit produces a magnetic field in the lamp that ultimately produces light. Since it has no electrode, the lamp does not fail catastrophically as do other lamp sources. It is vibration-resistant making it very suitable for high-volume traffic applications
The induction lamp is durable, and light output is not significantly influenced by ambient temperatures.
