The mercury lamps are not as efficient as the metal halide lamps but they do produce white light, it is "soft" light much less aggressive than the metal halide and some customers prefer this.

The lamps are cheaper to replace than the other types.

Other benefits of mercury are simplicity of circuits, reliability, and cost.

If you require a power lead or suspension chain please let us know they can be supplied with the light fitting at a small additional cost.
