Expand Spotlight Cone Angle to 170 Degrees

[Monkey Frog Studio]

Currently, the 'Y' cone angle cannot be set any higher than 90 degrees. I suppose normally this would be fine. However, in another program, I can set the spotlight to 170 degrees and I find this beneficial in some cases. For example, when you have something that looks more like a rectangular fluorescent light on the ceiling, placing a point light beneath it doesn't really work because the bright points, especially on reflective surfaces, on walls, floor, and ceiling, look like it's from a point light. However, in another engine, I simulated the broader lighting of a fluorescent light by using a spotlight set to 170 degrees and placing it very near the 3D model of the fluorescent light box. The result was a fairly nice wash of light on walls and floor with none on the ceiling. 

Currently, with only 90 degrees, I get a wider spot on the floor and maybe the lower parts of the wall (depending on how wide the hall or room is) and this looks worse than a spotlight.

Thanks for your consideration.

Have you tried the Box Light?

I have and was getting unsatisfactory results. But I may have been doing something wrong. I'll experiment more with the box light to see ...

I found I could do what I wanted with a few light boxes, but the shadow edge is very sharp compared to the point and spotlight. Thanks for the suggestion. Still, it would be nice, in some instances, to have the spotlight be able to go more than 90 degrees.
