Hi there,
We have for years been advocating the use of energy efficient Compact Fluorescent Lighting (CFL) to reduce loads and reduce system cost. A recent study by DEP in Maine has raised the alarm about mercury poisoning form these bulbs. If there is a breakage the resulting levels of mercury on the floor of the house are well above acceptable limits. Secondly there seems to be little serious effort to safely recycle these bulbs in a manner that keeps the mercury out of the eco system. I understand that LED lamps are mercury free. This would seem to be a much safer alternative. While many of us have mercury amalgams in our mouth the mercury is supposedly in a form that is not significantly ingested, whereas the mercury in a CFL is in vapour form when hot and powder form when cold, and therefore can pose a hazard to health. Can I suggest some discussion on this and can we do our best to keep it scientific, I don't mean to spread emotional alarm without due cause. Thanks, Carl Emerson Free Power Ltd. Auckland N.Z.
