Mercury vapor lamps
(see page 74) are commonly used to cure UV inks and coatings.
Although the total spectral output of such a lamp is very similar to that of a standard mercury vapor lamp
, the spectral bands actually shift toward longer wavelength.
Conjunctivitis caused by malfunctioning mercury vapor lamps
: Michigan, New Jersey.
In January 1995, pools of elemental mercury were found in a five-story factory building that had been converted to residential use in Hoboken, New Jersey; the building previously had been used to manufacture mercury vapor lamps
. This report summarizes the investigation by the New Jersey Department of Health (NJDOH), the U.S.
Fifty-three percent of the patients treated by ophthalmologists had used bed/booth devices, 17 percent had used reflective bulbs, 11 percent used mercury vapor lamps
, and 20 percent used unspecified UV devices.
Thus, a standard camera rated for incandescent light will have considerably less sensitivity when observing a scene lighted by mercury vapor lamps
. Sodium vapor, on the other hand, provides a somewhat broader spectral distribution than mercury vapor, but still lacks the red and infrared available from tunsten light.
Tenders are invited for mixed contract for supply and works for the replacement of luminaires with mercury vapor lamps
for new luminaires with led technology in the "san roque" frame
UV LED lamps are alternatives to the mercury vapor lamps
that have been around for more than 130 years.
Through that work, the company generates a variety of hazardous wastes, including paint and solvent wastes, used oil, and used fluorescent and mercury vapor lamps
, according to the EPA
In other lamps, such as energy saving high-pressure sodium (HPS) lamps for operation on mercury vapor ballasts, the lower power of the HPS lamps is a result of their power factor less than 0.85 compared with 0.93 for the mercury vapor lamps
(Ravi and others 1993).
The proposal includes regulations for two types of outdoor lamps: high-output double-ended quartz halogen lamps and general-purpose mercury vapor lamps
. It will require a minimum efficiency for high-output double-ended quartz halogen lamps with a minimum rated initial lumen value of 6,000 and a maximum initial lumen value of 15,000 starting January 1, 2016.
If you want even more functionality than the traditional PLC power supply provides, you may choose a new 27-step unit capable of up to 600w and running either Metal Halide or Mercury Vapor lamps
. There is also a new manual-analog "economy" power supply for high-performance curing at a maximum value.
