I have a shot in mind, where one of the elements of the shot would be someone sitting in front of a "television", but the TV won't be in the shot, but I want sort of a beam of light emitting from where the TV would be.

What would be the best way of going about this? I was going to use a softbox, and then make a square shaped cookie to go in between the strobe and the subject. Does that sound right or is there another way to get what I'm looking for?

It spreads too much.

use some sort of snoot over the tv? like a cardboard box to restrict some of the "spreading"

In the industry that I work, and have called a "career" for almost 22 years, and wished I completed my college tour and had a better "career"......

....we use a 1kw, or sometimes less wattage depending on the shot, with 1/2 to full Color Correction Blue (CTB), or even a party color blue like Steel Blue, or Cyan, or Peacock Blue,....something that gives out a blue hue.

The barn doors are usually taken off, and 2x3 black 'flags' are squared off in front of the beam.

Usually, some sort of diffusion like 1000H, or 250, 251 is added to soften the transmission.

In your case, this same formula can be achieved from a quartz security/work light from home depot, take some cardboard to cut the light into a square,(careful not to set the cardboard on fire, use tin foil on the transmission side to deflect the heat), the gell and diffusion can be found at a camera store, or a motion picture rental house, or a theater.

hope this helps.

Now that I think about it, I probably can't even use a strobe, probably will have to use a continuous light and maybe a longer exposure to burn the beam in a little? I hate when I get ideas and then have to sit and figure out how to make them work.
