What effect does it have to use a brand name which Google will try to correct with "did you mean...?"

When searching, mis-spelling a term may open a suggestion to search for something else, or completely replace it. For example, googling "Lightblub" will show results for "Light bulb". So would a product named as such be un-discoverable? How does Google's auto-correct of assumed typos affect SEO of a product name? Is it a bad or good idea to have a product name close to a real word or phrase?
