The best lighting is the common household incandescent light bulb because it comes closest to replicating the balanced frequency spectrum of natural sunlight. This seems a simple solution to the lighting problem. However, some sates and even entire countries are in the process of prohibiting use of these bulbs. California and Canada are considering legislation to phase out the sale of incandescent bulbs by 2012 and Australia’s goal is 2010. The European Union has a similar plan. Requiring everyone to replace incandescent bulbs with fluorescents is prompted by energy conservation concerns. But it’s not only a bad idea for etheric health, it’s potentially bad for the environment. Fluorescent light bulbs contain toxic mercury, which will end up in the environment unless extensive recycling efforts are mandated to accompany these changes. Sounds like a good time to contact your legislators.
