Mercury vapor lamps are bright, long-lasting light sources that are often used to light large areas such as streets, gyms, sports arenas, banks, or stores. The bulbs have an inner quartz tube containing the mercury vapor discharge. This is enclosed by an outer glass bulb that filters out harmful short-wavelength ultraviolet (UV) radiation.
There are two types of mercury vapor light bulbs sold in the U.S.
- “T” type light bulbs have a self-extinguishing feature that shuts off the light within 15 minutes after the outer bulb is broken.
- “R” type light bulbs do not have a self-extinguishing feature. They should only be installed in light fixtures that are fully enclosed by a lens of glass or plastic, or used only in areas where people will not be exposed to UV radiation if the outer bulb breaks.
Under normal operating conditions mercury vapor lamps provide efficient, long-lasting sources of light. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. UV exposure at this level can cause eye and skin burns, blurred or double vision, headaches, and nausea.
It can be difficult to know if you are exposed to harmful levels of UV radiation exposure because the symptoms can take several hours to appear.
