Hydrargyrum Quartz Iodide to give them their full name are a special type of high-intensity discharge lighting. The metal halide lamp will outperform halogens and as such, they are far better for floodlighting gardens and houses. These lamps produce a clear white light and are suitable for display or floodlighting, where the heat output from tungsten halogen lamps would create a problem. Metal Halide Lamps have an efficiency approx. 4 times higher than halogen lamps and xenon lamps.
Please note, HQIs cannot be used with dimmers, need to be cool when turning on, and have inbuilt circuitry that is only suitable for the correct wattage lamp.
Furthermore, these floodlights feature a singed front cover fitted with tempered safety glass and stainless steel clips for quick and easy access to the lamp. As these fixtures do not get very hot, they can be used with coloured gels to add an extra wow factor to lighting.
