Does high light planted tank need co2 and fertilizer?

yes. You will just grow algae running high light and no ferts and co2.

In as short as a one word answer; yes.

The explanation is that light, fertilizers and CO2 form a sort of triangle (or perhaps a better analogy would be a three legged stool). When one (or more) of these are out of balance, then the stool will not be usable and will fall over.

In an aquarium, the result of this imbalance would be algae formation and deteriorating health of plants.

Your question makes it sound as though you want a well lighted tank but are not too keen in having to go to CO2 and ferts.
You can have what would normally be considered a well lit tank without these. The term high light to folks with high tech tanks means being above a specific level of light. That level is normally beyond what most folks would want to simply light well and display a tank. To the high tech folks that display level of light would be considered low to medium.
I hope what I'm trying to say makes sense. The answers above are absolutely correct if you mean "high light" in terms of a high tech aquarium.
