Dimming Units

The new Remote Dimming Unit (RDU) by Blue Wolf eases balancing issues when utilizing mixed LED and incandescent bulb-type lighting circuits.

Many vehicle dimmers, aircraft dimmers, or any other type of instrumentation dimming technology normally have only one output channel.  However, that one output channel supplies both incandescent and LED lighting circuits with the same output voltage, but these two types of lighting bulbs do not produce the same amount of lumens when increased proportionally.

Generally LEDs produce a linear light output as the dimmer voltage is turned from 0% to 100%. Incandescent lights, on the other hand, do not produce light  at lower voltages. First, the filament has to heat up, and then after doing so, the filament starts producing light at a more exponential rate, with an increasing voltage. This incandescent lighting has more of an increasing curve rather than a linear output, like an LED, as the voltage or pulse modulation is increased.
