Deblanketing vectors derived from subdwarf photometry and spectrophotometry are used to transform published UBV photometry of globular cluster main sequences into an effective temperature scale defined by model atmosphere surface fluxes. Conversion of apparent visual magnitudes into apparent bolometric magnitudes is accomplished using subdwarf bolometric corrections, which are functions of effective temperature and metallicity. The results do not depend on stellar evolution models.
