We have obtained near-infrared spectra of L dwarfs, L/T transition objectsand T dwarfs using Subaru. Resulting spectra are examined in detail to seetheir dependence on the spectral types. We have obtained bolometricluminosities of the objects with known parallaxes in our sample, first byintegrating the spectra and second by K band bolometric correction. We derivethe relation between effective temperature and spectral type.Comment: To appear in May 20, 2004 issue of ApJ There is a companion paper by Tsuji, Nakajima and Yanagisaw
