Are sodium lamps hazardous?
This is because these lamps offer the most cost effective method of satisfactorily illuminating such areas. These lamps contain high levels of sodium and mercury, both of which are classified as ‘Hazardous’.
Do high pressure sodium lights contain mercury?
HPS lamps generally contain 10 to 50 mg of mercury. A small percentage contains more than 50 mg of mercury.
What was the major problem in producing a high pressure sodium lamp?
Although the sodium light requires less energy that other types of light and is more efficient, there are drawbacks to the use of these light sources. Metallic sodium reacts with the moisture in the air and can explode if the bulb is broken.
How do you dispose of high-pressure sodium light bulbs?
Recycling and Disposal Guide. High-intensity discharge bulbs contain hazardous mercury and must be recycled at a free drop-off mercury lamp recycling site.
How do you clean a high-pressure sodium bulb?
Light Systems says that if the HPS installation is in a clean environment, or if the reflectors are 1 to 3 years of age, it is possible to clean them with a solution of vinegar and water mixed at a ratio of 1:100. They also advise cleaning your bulbs and reflectors annually for best performance.
Can I get mercury poisoning from a broken light bulb?
Compact fluorescent light bulbs (CFLs) contain small amounts of mercury. A small percentage of this mercury can be released into the air if the bulbs are broken. Mercury can cause poisoning in some circumstances. Even so, people are encouraged to replace their “old fashioned” incandescent bulbs with CFLs.
What causes a high pressure sodium light to go on and off?
A high pressure sodium lamp cycling on and off usually indicates the lamp has reached the end of its normal life.
Are high pressure sodium (HPS) lamps better than LEDs?
Initially, LEDs will cost more to install, but the energy-savings, low maintenance costs, and lifespan puts them ahead of HPS lights. High pressure sodium fixtures are not as energy efficiency as LEDs. In fact, LED bulbs use between 40-75% less electricity than a HPS fixture. Who’s the winner? Clearly, LED.
What are high pressure sodium bulbs used for?
High pressure sodium lights are used for illuminating large outdoor areas. They emit bright yellow light. Typically these lights are used on sides of industrial buildings and in some street lamps. Sodium bulbs can last up to 20,000 hours. The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out.
How does the high pressure sodium lamps work?
How Does a High Pressure Sodium Ballast Work? Light. A sodium vapor lamp is a lamp that uses sodium to create light. It can come in a high pressure or low pressure format. Balast. The arc of gas that extends from one end of the tube to the other is created when ignited, and is made up of metallic sodium and mercury vapor. Operation. The inductive ballast is made up of a coiled wire.
How to dispose of high-pressure sodium light bulbs?
How to Dispose of High-Pressure Sodium Light Bulbs. Place the bulb in a padded container where it cannot break. The ideal container would be whatever specially designed box the bulb originally came in, or the one which contains the replacement bulb. If you don’t have such a box, use a cardboard box or other rigid container.
