John et al, At a forum on reducing heavy metals in municipal solid waste held in December, 1992, we learned (Chris R, Michael K, and I) from another breakout session (we were in the one with scrap PWBs and lead) that mercury is required in the fluorescent bulb "process". F.bulb mfgrs have been reducing the amount of Hg in these bulbs from 48 mg in 1985 to 42 in 1990 and even 27 mg reported in 1992. The T8 bulb is supposed to have less than 20 mg. One mfgr reported then that their bulbs had only 16 mg. (NOTE: All values are for 4' bulbs.) You Q about bulb life is appropriate, as that seems to be the barrier to lowering Hg content, since the Hg apparently combines with the bulb glass during its life. Either alternative glass or glass coatings are needed to further lower the consumption of Hg during bulb life and hence lower overall Hg content. Info on the forum was published by EPA in September 1993 (EPA 901-R-93-001 "Report of the National Technical Forum on Source Reduction of Heavy Metals in Municipal Solid Waste". I don't know what other states are doing, but we can recycle these bulbs under the scrap metal exemption in NH. We utilize new bulb packaging to protect replaced bulbs during storage and shipment.

If anyone has been using them, I would like to know the vendor contact, and how well they light, and how long they last.
