It lists all the individual lighting load instances. As @Eric Ringold mentioned, it is pulled from the E+ report, although it does convert W/m^2 to W/ft^2.

@kramerica, it sounds like you may want a zone total LPD, which we don't currently report. We do report a zone total vs. listing instances for plug loads, which didn't have an equivalent table in the EnergyPlus html file.
