We explore the brightness distribution of the largest and brightest (m(R)<22) Kuiper belt objects (KBOs). We construct a luminosity function of the dynamically excited or hot Kuiper belt (orbits with inclinations > 5 degrees) from the very brightest to m(R)=23. We find for m(R)< 23, a single slope appears to describe the luminosity function. We estimate ~12 KBOs brighter than m(R)~19.5 are present in the Kuiper belt today. With 9 bodies already discovered this suggests that the inventory of bright KBOs is nearly complete.
