We present optical spectroscopy of three brown dwarf candidates identified in the first 1% of the DENIS sky survey. Low resolution spectra from 6430–9150Å show these objects to have similar spectra to the brown dwarf candidate GD 165B. High resolution spectroscopy shows that one of the objects – DENIS-P J1228.2-1547 – has a strong 2.3±0.05Å equivalent width absorption line of Li I 6708Å, and is...
