"Red shift" or "amber drift" is the warming of colour temperature produced when you dim a tungsten lamp. This can be replicated with Robe fixtures with additive colour mixing LEDs, such as Multichip LEDs or MSL™, using our Tungsten emulation technology. When selected, the luminaire will mimic the colour temperature of a tungsten lamp as you lower the output to produce that classic warm glow. You can even decide the wattage you wish to emulate, such as a 750W, 1.000W, 1.200W, 2.000W and 2.500W lamp. This allows for seamless integration with traditional generic fixtures.
