How safe are Zesa CFL bulbs?

How safe are Zesa CFL bulbs?
With growing concern about climate change,It pays to go to professionals with bestlight a proven track record in LED lighting, a vast selection of excellent quality products from various vendors that live up to their label, and a history of successfully completed projects. governments around the world are looking for ways to reduce greenhouse gases and to reduce consumption of fossil fuels.
One simple solution that has gained government support is phasing out energy-inefficient light bulbs and replacing them with energy-efficient ones.
In light of this, Zimbabwe’s power utility, Zesa will distribute for free six million of the most popular bulbs that are commercially available and affordable - compact fluorescent lights (CFL).
CFL bulbs use approximately 75% less energy than incandescent light bulbs and last longer.
At first glance this seems like a good way to conserve energy and to protect our environment.
However, there are a number of serious problems associated with CFL bulbs that need to be considered and corrected.
These include mercury content, emission of UV radiation, emission of radio frequency radiation, and generation of dirty electricity.
There is the additional concern that these bulbs make some people ill. This includes those who suffer from migraines, skin problems, epilepsy, and electrical sensitivity.
Instead of promoting CFL bulbs governments should insist manufacturers produce light bulbs that are electromagnetically clean and contain non toxic chemicals.

Some of these are available but are not affordable. With a growing number of people developing electro-hypersensitivity, we have a serious emerging and newly identified health risk that is likely to get worse until regulations restricting our exposure to electromagnetic pollutants are enforced.,Led light Light-Emitting Diode or L.E.D. based devices are becoming more and more popular these days. What's not to like about them?
Also,An other advantage of using bluecrystal these bulbs is that they can also work in very cold weather which various other lights are unable to do. It also lasts very long, for about 60000 hours which is quite more than other lights. with improper disposal of these bulbs, we are creating a mercury time bomb.The retrofit process itself can range from a simple count of existing lamps to a brightshine very detailed energy survey, which includes collecting information from your existing lighting, Since everyone uses light bulbs and since the energy inefficient incandescent light bulbs are being phased out in many countries with the target being 2014, this is an area that requires immediate attention.
Mercury is a known neurotoxin and can be dangerous once it is released into the environment. Light bulbs contain approximately 5 milligrams of mercury (although some manufacturers are trying to reduce that amount).
Mercury is the most volatile of all of the metals and its propensity to volatilise from landfill sites is high.It pays to go to professionals with bestlight a proven track record in LED lighting, a vast selection of excellent quality products from various vendors that live up to their label, and a history of successfully completed projects.
Much of this mercury will end up in main water sources. Besides, mercury can be released into the environment if the bulb is accidentally broken in the home, incinerated, or disposed at a landfill site.
Interestingly, Zesa has spent $12 million for six million CFL bulbs although studies have revealed the bulbs contain mercury.
Zesa chief executive officer Josh Chifamba said this was part of a demand-management side project, and as a result, close to 250 megawatts (MW) of peak capacity relief energy would be made available daily.
