A Manufacturer s Perspective By Don Newsome, FMS #14 President, UV SYSTEMS, Inc. Definition of terms
uv ballasts . For clarity, this information uses the engineering terms lamp and lightweight or light assembly or bulb. Lamp is employed only to reference the device within a UV light which causes the UV and is particularly made up of a glass or quartz tube with 1 or 2 lamp bases. A UV light, light assembly or fitting is a housing, a lamp, a socket (or two), a reflector, a filter, a ballast, an on/off switch, and also a power cord or connector to some power supply. See Figure 1. Some UV lights likewise incorporate a cooling fan or

Introduction. Gas discharge lamps of numerous types, including medium-pressure mercury vapor, low-pressure mercury vapor and short-arc xenon include the most common reasons for useful numbers of ultraviolet radiation. There are also other artificial causes of UV for example High Intensity Discharge lamps (HID), concentrated arc lamps, carbon arc lamps, flashtubes, deuterium lamps, incandescent lamps, and LED s. Most of this informative article will involve the lowpressure mercury vapor UV lamps and the way they are manufactured, tested, and rated. When it comes to fluorescent lamp manufacturers we sometimes think of merely the big Fig. 2, many of the many SW UV lamps made three; GE, Sylvania, and Philips. However, you will find over 320 companies on this planet that manufacture some sort of fluorescent lamp, approximately 30 in the USA. However, 1 of them make UV lamps.
Ballast water is consumed by a ship to help keep its position within the water using sea valves or pumps. The ship's stability is determined by ballast water being consumed or discharged when cargo is loaded or unloaded, if your ship is traveling into different depths of water, or adjust trim or list for most other reason.From an environmental standpoint, the challenge with ballast water is it is really a means to transport aquatic nuisance species. To address and focus this issue, Carderock commissioned a different Ballast Water Research Laboratory Dec. 5 with the headquarters in West Bethesda, Maryland.
