We present L'and M' photometry, obtained at UKIRT using the Mauna Kea Observatories Near-IR filter set, for 46 and 31 standard stars, respectively. The L' standards include 25 from in-house "Bright Standards" with magnitudes deriving Elias et al. (1982) observations IRTF in early 1980s, 21 fainter stars. derive results of Sinton & Tittemore (1984). estimate average external error to be 0.015 mag bright 0.025 standards, 0.026 standards. new provide a network homogeneously observed establish reference stars MKO system, these bands. They also extend available which should faint enough accessible modern detectors on large very telescopes.
