Lighting Overview

Lighting is one of the most important aspects of our modern lives. Imagine how different the world would be without the advent of all of the various types of lighting sources we use each day. The following are some of the many different types of lighting products on the market today.

What Are LED Lamps? What is the Physical Concept of an LED?

LED lamps use light emitting diodes as a light source. Many different types of electronic devices make use of LED lighting today. They are common with digital clocks, flashlights, traffic signals, Christmas lights, and more. In recent years, technological advances with these lamps have even started to help them cross over into household and business lighting. The bulbs have been helpful for growing plants. In fact, NASA even used these types of lamps to grow plants in space. These sorts of bulbs are available in many different configurations too, and they are able to replace many of the bulbs you have around the house or office.

One of the biggest benefits is that LED bulbs actually have a lifespan of around 30,000 hours. Compare this to fluorescent bulbs with a lifespan of 8,000 hours and incandescent lighting at 1,000 hours. The downside is that the current cost of the bulbs and lamps is quite high when compared to the other options available.

What Are Fluorescent Lamps and Tubes? What is the Physical Concept Behind Fluorescent Light?

One of the most popular types of lighting, used in business as well as some homes today, is fluorescent. These lamps and tubes rely on gas discharge in order to light up and provide illumination. They use mercury vapor inside of the tube or lamp, and when you turn on the light, the little electric spark will agitate and excite the vapor, which causes the bulb to light up. These sorts of lamps and lights are quite popular in many places, particularly for office and industrial lighting.

Fluorescent lighting is popular for some very practical reasons. The fixtures themselves might not be cheap, but the rest of the cost of running this type of lighting system is, and those savings add up over time. The cost of the bulbs is lower than many expect, and the long lasting nature of those bulbs is where the real savings start.

What Are Halogen Lamps? What is the Physical Concept behind Halogen Light?

Halogen lamps are very popular today as well, and they actually have several different names to which people refer to them by, including the tungsten halogen lamp and the quartz iodine lamps. These bulbs are popular for a number of different sorts of products, including desk lamps and even some headlights. They have a number of advantages that help to maintain their popularity in the lighting field. The lights are cost effective, they produce brilliant light have offer great color rendering. The bulbs do not last quite as long as some of the other sorts of lamps out there do though.

These bulbs and lamps will contain a small amount of halogen inside of them. The filament is made of tungsten. When you turn on the lamp and an electrical charge flows through the lamp, it will cause the halogen and tungsten to react with one another, which provides the illumination.

What Are HID Lamps?

High intensity discharge lamps, or HID lamps, are similar to halogen lamps in the way they work. These lamps are actually using a chemical and electrical reaction to create their light as well. However, there are some notable differences. The lamps include gas and metal salts, along with the tungsten electrodes. When turning on the lamp, the salts melt and turn into a plasma, which can increase the light’s intensity.

These types of lamps have many variations and include metal halide, high–pressure sodium, low–pressure sodium, mercury vapor, and ceramic metal halide options. These are popular in many different types of lamps, including headlights. They have a number of benefits as well. They can produce a brighter and more natural light than the halogen lights. The HID lamps are also long lasting, and they utilize less energy. Other places where these sorts of lamps are in use today include warehouses and industrial buildings.

What Are Infrared Lamps and How Do They Work? What Are They Used for?

An infrared lamp is quite different from a traditional type of light and lamp. These emit infrared radiation. They are useful for a number of different types of items and devices, and some of the most common include those in the heating and communications field. They are helpful for night vision devices too.

The infrared heating lamps can work for heating food, and they are popular in the pet community for heating enclosures for some types of reptiles. When people need to heat a large area, they will often have several of these types of lights working in conjunction with one another. This is just the beginning of the uses for IR lights though. They are also quite helpful in preparing plastic for forming and curing coatings.

What Are UV Lamps and How Do They Work?

UV light is invisible to the human eye, even though it carries with it more energy than visible light. These sorts of lamps contain a small bit of mercury, and when a current passes to the lamp, it excites that mercury and causes the lamp to emit the ultraviolet light.

UV lamps are useful for a variety of different sorts of uses today. They are popular for disinfection and sterilization in water, for food, and in the medical field. These lamps are useful for rodent control, evaluating whether currency is real, forgery analysis, leak detection, mineral and gem inspections, crime scene inspection, and much more. In fact, some medical professionals even use UV light to help heal some types of wounds and injuries.

What Are Neon Lamps? What is the Physical Concept behind Neon?

Neon lamps have been very popular for quite a few years. One of the most common places to see neon is in the form of advertising on the front of a business. This sort of lighting works quite well for bars and restaurants, but many other types of businesses are getting in on the act as well. Printing places, bookshops, and more use neon signage today, as they see it as a great way to draw attention and pull in some foot traffic. In order for these to work well, they need to be in a prominent place where people will see it. Even those who do not have businesses can find use for neon lamps today. They often put them in their home as decor for game rooms, home bars, and the like.

What Are Incandescent Light Bulbs and How Do They Work?

When most people think of a light bulb, the incandescent bulb is the first thing that comes into their mind. These bulbs have been in use for more than a century, and they are readily available in stores everywhere. The lights work relatively simply through incandescence. This means the light they produce and emit comes directly from the heating up of the filament inside of the bulb. The bulbs are available in many different sizes, voltages, and wattages, which can provide a variety of different lighting solutions. These bulbs are common in nearly every facet of life today, from the lamp on the end table to ceiling fans, closet lighting, and much more.

What is Emergency Lighting?

Emergency lights are a part of many different buildings today. These lights will turn on whenever there is any sort of power outage. Since they run on batteries, they will be able to turn on even when there is no access to traditional power. Exit signs and lighting that will help to lead people safely out of a building fall in the category of emergency lighting. This sort of lighting needs to have the ability to come on automatically in the event of an outage or emergency when the normal lighting fails. It needs to be bright enough so that people can see easily. Some of the most common places where these sorts of systems are in use today include college dorms, offices and in some residential buildings that have a high occupancy.

What is Safety Lighting?

Safety lighting is very similar to emergency lighting. Both are essential for helping people during an emergency or crisis happening in or around a building. However, when most people think about safety lighting, they think about the lighting in areas such as underground structures or parking structures. The lighting is generally not quite as bright as other sorts of lighting types are.

What Are Light Fittings and Luminaires?

Light fixtures, also called luminaires or fittings are the actual physical construct that will hold the bulb and help create the light by allowing the electricity to pass into the bulb. Since there is such a wide range of lighting types available today, it is important to choose the right fittings and luminaires. Whether outfitting a warehouse, an industrial space, office cubicles, or a home, there will be a need for different types of fittings and lamps to provide a solution to all of the lighting needs. Fittings are available for everything from halogen and LED lightings to HID, fluorescents, and incandescent bulbs.

What Are Considered Indicators in Lighting?

An indicator is one of the most common parts of many different types of electrical devices today. The indicator lights can let you know if the device or unit is working properly or if there is an issue with it. The indicators can do more than just determine whether the unit is working properly or not though. Different indicators can mean different things. One could mean the machine or device is on and another could indicate there is a problem in a certain part of the machine.

What Are Torches and Handlamps? Which Professions Require Torches and Handlamps?


The terms handlamp, torch, and flashlight are all synonymous. They simply refer to lighting that is portable and that you can take with you in your hand. Whether it is something as simple as a small penlight, an LED torch, a lantern, or something similar, they all fall into the same category. These sorts of lights are extremely useful. Everyone should have at least one torch on hand at home, in the vehicle, and at work. You never know when you might need it. They are also extremely helpful for many different sorts of work.

Some of the top professions that require these sorts of lights include police officers, security, doctors, firefighters, pest control pros, mechanics, and soldiers. Everyone will likely need to have access to a torch or handlamp at some point in his or her life.

What Are Lighting Components and Accessories

In addition to the fittings and the bulbs, one also has to consider the many different options for accessories and lighting components available. Some of the popular lighting components and accessories include wireless controls, dimmer switches, ceiling roses, switches, lighting ballasts, mounts, and plugs. All of the different types of accessories and controllers out there can help to give people much better control over their lighting system, and they can help to provide more options. The right controls and accessories can make a world of difference to the lighting situation in the home, office, warehouse, and more.

Neon lamps are actually tubes that contain the gas neon. The low–pressure neon in the tube produces light as soon as an electrical charge starts to run through those tubes. It may take a second for this to happen, which is why there is the short flicker when first turning on many neon lights. The glass tubes that contain the neon are bent into different shapes to create letters, digits, and other characters. The literal flexibility of these sorts of signs is one of the things that make them popular with many businesses. They can have signs that say nearly anything they need.
