Richard the mercury content per bulb is a required input for LEED Online. The way the form is set up, it calculates the building average picograms/lumen-hr within the form, so this can't be an input. I would try to get this information from the manufacturer.

Look at the mean lumen output and the average lamp life in hours (based on 3-hour starts). As an example: 32W T8 lamp Mercury: 83 picograms Hg per mean lumen hour Mean Lumen: 2,385 lumen Lamp life @ 3h: 20,000 hours Total mercury = (0.000000000083) * (2,385) * (20,000) Total mercury = 0.00396 g of mercury, Or 4.0 mg if you short hand it.
