We constructed the composite luminosity function (LF) of cluster galaxies from the SDSS Cut & Enhance galaxy cluster catalog. Major advantages of using SDSS Cut & Enhance galaxy cluster catalog are following. 1. The sample is large. Our LFs consist of 185 clusters, while previous works are from dozens of clusters. 2. Cut & enhance cluster selection is uniform and not biased against special LFs. 3. Large area coverage of SDSS enables to subtract background locally. 4. CCD imaging data of SDSS enables us to use accurate photometry, color and morphological information on each galaxy. We study the dependence of cluster luminosity function on galaxy morphology, radial distance from the center, surface galaxy density. We also compare the cluster luminosity function with the field galaxy luminosity function (Blanton et al. 2001). We discuss the environmental effect on galaxy formation and evolution. T.
