The determination of ages for metal poor globular cluster stars using the relationship between stellar effective temperature and color, in order to transform isochrones from the L, Teff plane to the M(V), color plane is described. Estimates of the effective temperatures of metal-poor field subdwarfs deduced from the ratios of the integrated fluxes to the 12000 A fluxes of the 4 subdwarfs are in good agreement with published results. The stars are fainter than the models in the infrared, but the UV fluxes are in good agreement with model predictions.
