This report presents the most recent measurement of the longitudinal structure function F-L obtained from e(+/-)p interactions recorded by the H1 experiment at HERA accelerator. The data at different proton beam energies of 460 GeV, 575 GeV and 920 GeV are used to determine F-L. The measurements are obtained for low values of photon virtuality Q(2) down to 1.5 GeV2 and low values of Bjorken variable x down to 2.7.10(-5). Direct measurement of F-L allows also to measure structure function F-2 which represents a model independent determination without extra assumption on F-L. The data are compared with the predictions based on NLO and NNLO QCD calculations.
