Almost all modern high output light sources depend on using mercury inside the lamps for operation. When considering the environmental impact of the mercury in lighting, we must take three factors into consideration:
• The type of mercury (solid or liquid) which is present in the lamps,
• The amount of mercury present in a particular type of lamp, and
• The lifespan of the lamp which will determine the amount of mercury used per hour of operation.

Ultraviolet Radiation Burns from High Intensity Metal Halide and Mercury Vapor Lighting Remain a Public Health Concern – Notice to Schools and Other Indoor, All-Purpose Facilities Where Light Bulbs are Subject to Damage

Broken and unshielded high intensity metal halide and mercury vapor light bulbs continue to cause eye and skin injuries, particularly in school gymnasiums. To prevent these incidents from recurring, FDA recommends the following in schools and other indoor, all-purpose facilities where the light bulbs may be broken:

Comparison of Electrical Energy Consumption, Light Output and Co2 Emissions

Based on operating the lighting fixtures 24/7 for one year, replacing the Metal Halide lamp fixture with an induction lamp fixture will reduce Co2 emissions from electrical power generation by 574.8 KG (1,270 Lbs) or about 55%.

Again, this is the figure for one fixture, there will be dozens or even hundreds of fixtures in a facility... thousands in a city or region. Replacing inefficient lighting technologies with energy efficient Magnetic Induction lamps can contribute to significant energy consumption savings and Co2 emissions reduction.

The greenhouse gas equivalencies calculator can help you understand just that, translating abstract measurements into concrete terms you can understand, such as "equivalent to avoiding the carbon dioxide emissions of 183,000 cars annually."

This calculator may be useful in communicating your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing greenhouse gas emissions.
