Have you ever heard about difraction? "detailed light" like this doesn't happen in real life...
I'm sorry to burst your bubble, but he's right.
You might want to consider taking down the prefab. It's pretty, I'll give you that. There's an obvious effort shown. Although it's not hard to figure out how to do this, you've given a good attempt at creating a good example of it.
A thing to consider is the usefulness of the prefab... How, exactly, would someone make use of this in a map? A single replication of the prefab itself slows the compilation time considerably.
Disregarding these criticisms, you might also want to note that the texture of the grate that you're using has diagonal parts to it, as well. These are not shown in the shadow (an obvious disregarding of detail).
Please, consider the following. Even though the prefab is nice-looking and creative, it's useless. It still shows effort (disregarding, again, the diagonal parts). Good job, I guess I could say.
Keep up the effort...

I would advise people not to do this for maps intended for gameplay.
Not only would multiple uses of this prefab eat into your brushcount, the overuse of the blocklight tool will result in increased compile times and potentially affect ingame performance.
You dont need to download it... If you have a crapy computor that takes hour to compile or to run it,
you can wrote your comp specs so we know what wo compare with :)
