I mean a light like morning sunshine coming in from a window. Would a grided softbox work?

No, you need the hardest possible light for a sunlight effect at macro distances. Use a flash head.

Balcar used to make fiber optics cables that attached to their 7 in. reflectors that were flexible and could be used to do essentially what you want. They are long out of business but maybe someone else makes a similar product or perhaps you can adapt an existing fiber optics cable to your own lighting and make that work.

So a deep silver softbox such as Ricebowl without the diffusers does not do the job?
@Peter: What are the fiber optics used for?

The sun is remarkably close to a point source and, being near infinity, is difficult to reproduce in the studio. Most sunlight simulations reveal their shortcomings in subtle ways. The cheapest route is a flash unit at tele zoom setting and, at maximum distance, is very convincing. Subject magnification plays a role, but is best kept as an advanced topic. Speedlight as key in near-macro range of .25X:

Use a speed light flash. They have a built-in fresnel lens and can be controlled with wide lens/telephoto lens settings.

Any softbox will look like north facing window light—the oposite of what you want.

Here's an interesting video showing point-source lighting



This was shot with a Nikon flash on a Custom Bracket CB Mini RC. Notice that the shadow is not as hard as the Broncolor flash—but close enogh for what the OP wants. https://www.bhphotovideo.com/c/product/1159082-REG/custom_brackets_cb_mini_rc_cb_mini_camera_flash.html#!

People so often ignore this and end up with mushy (or double) shadows.

OP if you want this super hard light you best bet (for flash) is one of these:

Godox AD360


because it has a mini bare bulb with a tiny flash tube to get as close to a point source as possible



Snoot it so light doesn't go everywhere (unless you want it for fill!)

Not quite macro scale, but here's another studio creation. Goal is that clear sunlight of early morning. This has key illumination from a 3" fresnel, a non-too-cheap flash fixture from Profoto that requires a pack. The combo delivers four f-stops of energy above a camera flash, which is useful when I want to shoot at f/16:



Fill is provided by diffusion panel and Speedlight—no blue shadows, thank you.

Well, a Google search for Balcar fiber optics yields nothing at all. I wish I had bought them when they were available. Basically it was a second 7 inch reflector that attached to the one on your strobe head - that led into the flexible fiber optics tube, which, like a gooseneck lamp, could be positioned how you wanted.

Here's a standalone fiber optics microscope lighting device that, conceptually, is along the same lines. Maybe it will give you some ideas. Much smaller and more direct (and directable) light source than any simple bare head.
