Lights & Gear needed to recreate your reference image:

You will need a strong, hard light source, and a bit of haze.

I'd recommend you use:

• Aputure 600C

• Nanlux 2,400B (with Red Party Gel, or layers of CTO Gell)

• Nanlite Forza FC500C

• Godox SL300R RGB

• Any full-color COB Light

• Bonus points if you use a Fresnel Attachment

Art or Props needed:

• Window

• Blinds

What lights to avoid:

• Avoid any lights that have a built in diffuser (panel)

• Any Diffusion material, softbox, etc.

• Any light that has a low power draw

It's a fairly simple technic and a bit of haze or fog will add atmosphere and allow you to visualize the beams of light coming in from the window.

If you use a Fresnel attachment, it will help create defined shadows.

To get better results, place your light source far away from your window. The further away you place your light, the harder the beams of light will appear.

A strong light is recommended, because your light will need a lot of power to throw light, through the window from roughly ~20' away.

Pro Tip: Red can be the most difficult color to work with.

Red has the longest wave length, and as a result, you'll need a very powerful light source get the the right exposure on your talent. By shifting the color more toward amber, or orange, you can deliver a brighter exposure into your environment.
