Light controllers regulate the current used by an LED light. Without a controller, light output would vary dramatically, and the LEDs wouldn’t last long.

This light controller has a built-in potentiometer that allows you to control light intensity. It’s a convenient way to control image brightness without changing depth of field, introducing image noise, or causing image blur.

This light controller is compatible with certain Spectrum Illumination high-flux Monster LED lights. We normally ship a standard controller (without the potentiometer) with each Monster light your purchase. For a small additional charge, we will substitute this controller with the potentiometer. The price shown above only applies when purchasing this controller separate from the light.

To extend the life of your LED light, we recommend strobing. This controller has both PNP and NPN strobe inputs. To enable the light, either connect the NPN strobe input to ground, or connect the PNP strobe input to 5 – 24 VDC. Your light will turn on within 3 microseconds of the strobe signal, and will remain on for the duration of the signal. For best results we recommend using your camera to trigger light controllers, rather than the device that triggers your camera. For example, with our Ace cameras, you can use the “Flash Window Signal” output to trigger this light controller.

We also offer a version of this controller with a 0 – 10 VDC input to control light intensity. If you need greater control of the strobe on-delay, duration, or number of flashes, use the Monster Brain Controller in conjunction with this item. (See links below.)
