I received this circuit board for Skilhunt - does it look wrong?

I received this circuit board replacement for a Skilhunt H04 headlamp. What’s the white stuff on it? This part just looks like junk?

That looks like a “conformal coating” meant to protect the components by providing some degree of water and shock protection. Nothing wrong.

Does this help ?

You need to rotate the image 90 degrees.

Your driver looks good to me.

The “glue” helps keep bulky components like the big-ass inductor in-place. Not as good as potted, but definitely helps nail things down.
