High Bay Retrofit Lamps

Upgrade your existing HID high bay fixtures to LED without replacing the whole fitting. Our High Bay Retrofit Lamps offer a practical way to reduce lighting energy use and keep compatible metal halide fixtures working in warehouses, workshops and other high-ceiling spaces. Long LED life also helps reduce the frequency of lamp changes in hard-to-reach areas. These lamps are backed by warranties up to five years.

Choose the light output and colour temperature that suit your space, with options for 347V electrical systems as well as other supply voltages. Selected models offer built-in surge protection, dimming and selectable colour temperatures. The range includes EX39 mogul-base lamps and models rated for enclosed fixtures, alongside lamps designed for open fixtures.

Match the lamp to your socket, supply voltage and available space inside the fixture before ordering. Check each model's open or enclosed-fixture rating and installation requirements. These ballast-bypass lamps require a qualified electrician to disconnect the existing ballast and complete the conversion.
