Unlike any light bulb you know, Forest Anion™ Light Bulbs feature a negative ion generator that emits negative ions into the air. These negative ions neutralize positive ions that can be present in the surrounding. With Forest Anion™ Light Bulbs, those nasty airborne particles like Smell, Odour, Smoke, Fumes, even harmful chemicals etc. will be thoroughly eliminated, leaving the air cleaner, fresher and healthier.

According to the company, if every American household replaced only one of their incandescent bulbs with an energy-efficient CFL, it would save more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.

In addition, Megalight presented its growing LED product line, which lasts a lifetime and 100% mercury-free.

We're constantly being told that compact fluorescent light bulbs (CFL) are better for the environment than older, but what you may not know is that the bulbs may actually be a lot more dangerous for your health.

Incandescent globes will be phased out in November 2009 because they burn on average 80 per cent more energy than the newer bulbs.

Critics claim the CFL light bulbs give off dangerous amounts of radiation and can cause skin disorders and medical conditions a claim that is strongly denied by both industry and medical officials.

"You would have to suffer from a skin condition such as Lupus and sit under a light bulb for an hour to develop any kind of adverse affect," Dr Stephen Schmack from the College of Dermatology said.

Another health concern that has some people worried is the concentration of mercury contained in the CFL light bulbs.

CFL's contain small amounts of mercury as vapour inside the glass tubing and average about 4.0 mg per bulb.

When the bulbs are broken or smashed open, a white vapour mist can come out and potentially cause dangerous levels of mercury in the surrounding environment.

Crime writer Clinton Smith is convinced the UV radiation from the new 'green' globes helped contribute to his head cancer.

"The dangers are not only great, they're going to be unavoidable," Clinton told A Current Affair.

"I'm going to put an incandescent globe on my desk – I don't want to be irradiated all my working life."

Clinton is even going as far as not purchasing the CFL light bulbs and stockpiling the older incandescent bulbs.

"I'm going to have a lot of them and my shed will be filled," Clinton said.

"I'm very concerned about skin cancer with the CFL bulbs and I know that the incandescent globe won't give me it."

Although serious health problems resulting from one broken light bulb is rare, the federal government recommends that you wear gloves, protective clothing and sweep up the broken globes to prevent toxic dust from spreading through the home.
