What do you mean, you want to have your spot lights chase? Do your spots require special power configs?

i want to be able to slowly fade them out rather than just cut off abruptly

plug it into your lighting system! find a spare dimmer, you may have to run a cable, but its cheap. You will want to consider opening the spot and seperating the power for the bulb and the fan so that you can plug the fan into a constant power source and the bulb can go onto the lighting system.

Instead of splicing a dimmer into the fixture, I would cut the spotlight cord short and plug it’s end, or coil up the extra cable and attach it to the boom. It is a follow spot we are talking about right? You than do a in-line dimmer mounted to the fixture stand.

Next question we need to know is if this is a arc source/HMI or Zenon follow spot, or halogen lamp spot light. Beyond that if assumed to be halogen, is it a 120v lamp or a 360w low voltage one?

In the past, I have used single circuit dimmers with C-Clamps mounted to the frame of them. Very simple to just clamp them to the stand and control the light in a simple way. Otherwise as said, if you have spare dimmer channels, it’s simple enough to control them with the main dimmers.

Spotlights commonly have “boomerangs” full of gel you can select by way of lever or de-select. They also commonly have dowsers, Irises and black out shutters. There is a simulated way of dimming the spotlight technique that entails using the iris and dowser at the same time to reduce the output for a fad to black.

If a 1Kw halogen 120v lamp, no dimming won’t hurt it, instead it will lengthen the life. This fade to black as opposed to the fixture dousing - not turning off is however a common stage convention to see. That snap off of the light depending upon the application, can be useful in separating the non-reality part of say a song from when the talent goes back into character.
