Unless you specifically say "visible light" I assume "light" to just mean electromagnetic radiation.

The idea that a and very small wavelength would cause a black hole doesn’t really make sense to me since I thought a black hole requires mass.
It's mass OR energy.
Light, even though massless will still bend (and be affected by distorted) spacetime because it has energy in form of momentum. (See: gravitational lensing).
There is no upper limit, so really this comes down to how big the universe is.
It's properties would be that it's extremely low energy ... and basically impossible to detected as you'd need a universe-sized antenna.
For short wavelengths you'll eventually concentrate so much energy in one spot that it will form a black hole. So that would be the lower limit.
And those of us in positions of authority

That's by far the pettiest shit I've seen today.
I get off the train in Basel, which is right at the border. Don't even have to exchange it, most shops in the area will take Euros.
I've seen a guy with a "Money for Weed" sign in Hamburg the other day. He obviously got some money.
What the obnoxiously sanctimonious guy said.
Monetarily challenged person?
I generally don't, especially not when people come up to me and ask for money. Though that's just because I don't like unsolicited interactions with strangers in the first place, not because they are beggars.
However, I never use cash in Switzerland so every time I come back from Germany I'll just dump all the change I accumulated there on the first beggar I find.
The prequels told a story that deserved to be told and was mostly internally consistent.
Hard disagree on both.
I guess. But it wouldn't be light with a wave length anymore. It would be a black hole.
That's an interesting thought. I don't think so. Once you get the black hole it should gain mass. But that's really hitting the limit of my physics knowledge.
