Toxic Light – The Dark Side of Energy Saving Bulbs
A look at how dangerous the new energy-saving light bulbs are. The EU has banned many incandescent bulbs in favor of Compact Florescent Lights (CFLs). CFLs emit serious toxins while being used. All Florescent lights contain Mercury. There is enough Mercury to pose a serious health risk in the event of a CLF breakage. People are being told to run out of the building for 15 minutes, open windows and turn off the heat. Additionally the bulbs do not last as long as advertised and they take a long time to warm up, decreasing in brightness over time. The light they emit is not a full spectrum steady light. Few Bulbs actually get recycled and they need to be treated as hazardous materials when discarding them. Consumers be alerted!

I hate energy bulbs with a passion, they give me a bad head. I have a good store of 'normal' bulbs that probably won't last forever.

I prefer the light given off by the traditional incandescent bulb. It seems warmer, less harsh on my senses. However, I don't think that CFLs are as hazardous as some people like to make out. As I understand it, they only contain about 1/100th of the mercury found in an old-fashioned oral thermometer and I remember breaking those and playing with the mercury balls, as a kid (probably explains a lot about me as an adult LOL).

Does anybody still buy these old CFLs? They seem to have been superseded by the far more effective Halogen and LEDs now. Incidentally, although the EU banned the old incandescent bulbs, some switched-on (sorry) guy started importing them from China by describing them as small, high-efficiency, electric heaters, by virtue of the fact that they give off far more energy as heat than they do light. I'm not sure how long he got away with that for, the EU, being the dictatorial bunch of plonkers that they are, will have, undoubtedly, pulled that rug out from under him by now.....

If i was a plant i would love living under CFL's,but being human i only have one retina.! As established by many industrial safety studies, the most harmful light for all mammalian eyes is in the blue to violet range, with wavelengths from 430 to 440 nanometers. Unfortunately, all fluorescent lamps emit a large portion of their total energy in a narrow spike at 435.8 nm, precisely in the most eye-damaging region. Adult humans are somewhat protected from this damage because our lens yellows with age, just as varnish does, and for the same reason of slow oxidation by free radicals created through long-term irradiation with light. This yellowing filters out much of the blue and violet from about our early twenties on, but these harmful wavelengths can freely penetrate into the still more transparent eyes of children. There they can cause an accelerated buildup of destroyed photoreceptors which diminishes the capacity of these to self-repair. This can ultimately lead to the degeneration of the macula in later years. It is therefore probably no coincidence that the non-senile people who now experience the much earlier onset of macular degeneration are the first generation who spent much of their youth under fluorescent classroom lamps. The issue has not been studied officially, so there is presently no proven link between this early unprotected exposure to the most damaging light in the visible spectrum and the earlier appearance of the damage generally connected with this type of exposure.
