We have performed a non-LTE spectroscopic analysis using far-UV and UV data of the central star of the planetary nebula K1-26 (Longmore 1) and found T_eff=120±10 kK, logg=6.7^+0.3_–0.7cm/s2, and Y≃0.10. The temperature is significantly hotter than previous results based on optical line analyses, highlighting the importance of analyzing the spectra of such hot objects at shorter wavelengths. The spectra show metal lines (from, e.g., carbon, oxygen, sulfur, and iron). The signatures of most elements can be fit adequately using solar abundances, confirming the classification of Lo 1 as a high-gravity O(H) object. Adopting a distance of 800 pc, we derive R_*≃0.04 R_☉, L≃250 L_☉, and M≃0.6 M_☉. This places the object on the white dwarf cooling sequence of the evolutionary tracks with an age of τ_evol≃65 kyr.
