Small led distance to plant

I grow with CFL, but have one small LED for plants. Like this . Some 10W.

What was the safe distance to avoid possible bleaching?
I have read about it, but have unfortunately forgotten, and most of topics and articles cover big lead panels issues.

Would like to use to light from side

12"

If the light doesn't heat up your hand, it's not too close.

Even for small ones? I thought that was for bigger ones.

If you already know the answer, why are you asking?

Well, I consider 10W as a small one.
