The irradiances of 37 spectral lines emitted by mercury pencil-type lamps were measured by comparison with calibrated continuum sources. The lines span the region 230–590 nm. For the 14 most prominent lines the absolute irradiances should be useful for radiometric calibrations at an uncertainty level of ∼15% (95% confidence). The ratios of the irradiances for this same group of lines are significantly more reproducible; they should be useful at an uncertainty level of ∼10%.
