The main reason for color temperature changes lies in the physical properties of these lamps
Filament Properties
In incandescent and halogen lamps, light is generated by heating the filament until it starts to glow. The color of this glow is directly related to the filament’s temperature.
Voltage-Dependent Light Emission
When dimming these lamps, you are effectively reducing the voltage supplied to them. This lowers the filament temperature, causing the light to shift towards warmer (yellowish) tones.
Traditional Dimming Limitations
Conventional dimming methods simply reduce the power delivered to the lamp, which inevitably leads to this color shift.
Solution
To maintain a stable color temperature, it is recommended to use specialized stage dimmers that support high-frequency phase dimming, such as:
Efficient DMX Signal Management
Splitting and amplifying the DMX signal is key to stable stage lighting performance. Read our article on DMX splitters to prevent flickering and signal loss in incandescent and other lighting fixtures.
