These are the standard tubular metal halide lamps they give an immense amount of light for any given wattage.

They run on Mercury control gear as there is no such thing as metal halide control gear.

The light output is crisp and very white.

These lamps are used for flood lighting all kinds of outdoor lighting and increasingly in large stores as they show colours very accurately.

They are also known as Euros, Kolorarc, HPI-T, metalarc,HIE, HIT, dependent on manufacturer. if in doubt please call us.
