LED VS Fluorescent VS Halogen Lights Comparison
Lights are the most used devices everywhere in the world. We cannot imagine our lives without lights. We cannot see anything at night without lights. Light is the most essential and basic necessity in our lives. As We use lights everywhere, people often get confused about which type of light they should buy. The lights industry is one of the largest industries in the world. The Global market of lighting size was USD 118.33 Billion in 2019. Multiple types of lights are available in the market. Every lamp is made explicitly for a particular task. You must have basic knowledge about which kind of light fulfills your needs and fits in your budget. This article will help you choose which light is best for you. Here we will guide you about Led, Fluorescent, and Halogen lights to help you make a wise decision:
History of Light Bulbs:
Many historians claim that 20 scientists invented the light bulb before Edison, but Thomas Alva Edison was the one who invented the first commercial incandescent light bulb. Later On, Elmer Fridrich and Emmet Wiley developed the Halogen Bulbs(in 1955). Both of them were working at General Electric. General Electric patented a commercially usable halogen lamp with iodine gas in it in 1959. Halogen Bulb was a modified form of Incandescent bulb. George Inman was the one who led the team of scientists at GE(General Electric), and this team developed the first practically usable fluorescent light, which was sold first in 1938. In 1962, Nick Holonyak, Jr.( the father of LED lights) invented the first light-emitting diode(LED).LED technology is the latest technology being used in the lights industry.
Working of LED, Fluorescent, And Halogen Lights:
The Working of LED, Fluorescent and Halogen Lights is explained below:
A Fluorescent light is basically a gas discharge tube in which the electricity is used to excite the mercury vapours. Then the excited mercury atoms produce ultraviolet light, and as a result, the phosphorus in the tube fluoresce (glow/shine brightly). And in this way, Visible light is produced in Fluorescent tubes.
Fluorescent lights use ballast to work. The Ballast regulates the electric current to the lamp and gives sufficient voltage to start the Fluorescent lamp. At the initial stage, Fluorescent lights require a starter to ionize the mercury vapors that begin fluorescence. In a fluorescent lamp, argon, neon, or some other gas is mixed with mercury vapors. In the light, the pressure is about 0.3 of atmospheric pressure. The lamp is internally coated with a fluorescent coating made of varying blends of metallic and rare-earth phosphor salts. The electrodes of the lamps are made of coiled tungsten. The thermionic emission is improved by using a mixture of calcium oxides, barium, strontium. Ballasts are used in fluorescent lights because the fluorescent lights can destroy because of the uncontrolled flow of current. The life of a fluorescent lamp depends upon the life of the cathode electrodes. Companies change colors by changing the amount and combination of the phosphor material inside the fluorescent light.
LED Lights; How does the LED work?
Full form of LED is Light Emitting Diodes. As its name indicates that it contains diodes. An LED light consists of many small diodes which produce light when the electric current is applied. LED lights work on the principle of electroluminescence. This means that the diode produces light when the current passes through it. The electrons move from an electron full side to the side where there is a deficiency of electrons across the p-n junction. LED lights are very energy efficient and a bit expensive. LED lights are twice efficient as fluorescent lights. The LEDs do not require a warm-up at the start and can provide the maximum brightness in just seconds of turning it on.
Halogen Lights: How Halogen Lights Work?
A Halogen Light is a modified form of incandescent light. As its name shows, Halogen lights are the lights that use halogens to produce light. Halogens are the chemical elements from Group 17 in the periodic table. We know about the Incandescent lights(invented by Thomas Alva Edison). There’s the problem in the Incandescent light: when the tungsten filament glows, it starts evaporating and depositing on the inner wall of the glass of the incandescent bulb. After some time, the tungsten filament becomes weak, and at the end, it eventually breaks(fuses). Halogen lights solved this problem by using a small amount of halogens. Tungsten filament is also present in Halogen Lights.
When the tungsten filament glows and becomes hot, it starts evaporating, and it combines with the Halogen( such as bromine and iodine) present inside the Halogen light bulb. After that, the Tungsten-Halogen molecules deposit on the filament. This is how halogen gases prevent the blackening of a halogen light bulb’s inner wall and prevent the weakening of the tungsten filament. Halogen lights are the modified form of incandescent lamps because many things are similar in both lamps. Halogen lamps are very similar to incandescent lamps and also a great alternative to incandescent lamps. They are more efficient, reliable, and brighter than average incandescent lamps. Halogen lights can work at a higher temperature. The small glass envelope of halogen lights is covered with a large outer layer which maintains the internal temperature and prevents the contamination of the inner bulb. Halogen lights come in many shapes—the everyday use of Halogen lights is as floodlights and spotlights. Halogen lights are also sensitive to skin oils which can cause them to malfunction or burst. These lights are not very efficient as compared to LEDs or Fluorescent lamps.
While Buying lights, we check their efficiency, durability, life span, recyclability, brightness, and many other factors. Here we are going to discuss LED, Halogen, and fluorescent lights and compare them:
LED VS Fluorescent VS Halogen Lights Power Consumption:
Power consumption is the most important thing we should check while choosing lights. We should choose a light with less power consumption and better luminous flux(more lumens per watt). Comparing two bulbs that give out the same amount of light, the LED bulb uses 6-8W, and the fluorescent bulb uses 13-18W. So we can say that the power consumption of fluorescent lights is approximately two times that of LED lights, which means that LED lights are more efficient than fluorescent lights. So if you use LED lights instead of fluorescent lights, it will help you reduce electricity bills.
Halogen lights emit 80-90% of their total energy as heat. Comparing the power consumption of LED lights, Halogen lights, and Fluorescent lights for illuminating the same area, Halogen Lights’ power consumption is much more than Fluorescent lights and LED lights. It would be best to consider buying Led or Fluorescent lights as Halogen lights will increase your power consumption. Fluorescent lights can be used as an energy-saving alternative if the LEDs are not available.
LED VS Fluorescent VS Halogen lights Brightness and Luminous Flux:
The number of Lumens per watt describes the amount of light emitted by a source. LED lights produce an average of 74 lumens per watt. In comparison, Fluorescent lights have an average of 63 lumens per watt. So LED lights are more efficient. So You will save your electricity bill if you use LED lights. Brightness is one of the important factors to consider while choosing lights. The Brightness of LED lights remains the same even after using them for years. But the Brightness of fluorescent lights decreases with time. A Halogen light bulb of good quality provides you 19 lumens per watt which are lesser than other types of lights. So We can say that you should go for LED lights as they offer more lumens per watt.
LED VS Fluorescent Lights VS Halogen Lights in terms of Health & Life Span:
The life span of lights is the length of time for which lights function correctly. More Lifespan means that the light will work properly for a long time. LED lights last about 50k hours. You can also find the LEDs made in 2000 working today. This shows that how durable LED lights are. The Fluorescent lights last about 24,000-36,000 hours. Halogen lights have an average life span of 2,000 hours only, far less than LED and fluorescent lights. LED lights usually last more than other types of light. Switching lights On and off frequently does not affect the life span of LED lights. On the other hand, it affects the life span of fluorescent Lights and Halogen lights. If you want to buy Halogen light bulbs or fluorescent light bulbs, you should keep in mind that turning them OFF and ON frequently shortens their life span. The life span of lights also depends upon the quality of light, and it also varies from brand to brand. LED lamps have a short life span when used at high temperatures(More than 85°C).
LED VS Fluorescent VS Halogen Lights in terms of Cost Savings:
We all want to save our money. Most people are concerned about their electricity bills. The buying price of LED lights is more than Fluorescent lights. This is why some people still prefer buying fluorescent lights rather than buying LED lights. But Fluorescent lights are not as efficient as LED lights. The life span of LED lights is more than Fluorescent lights and LED lights also use less electric power. The LEDs can also work at low power levels, thanks to their energy-saving ability. The LED lights can efficiently work on the UPS and generators without degrading performance. LED Bulbs reduce electricity bills. So we can say that LED lights are more economical and they help us save more money. The buying price of Halogen Light bulbs is less than LED light bulbs and fluorescent light bulbs. Halogen light bulbs use a lot of energy and have less efficiency. In Halogen Light bulbs, a lot of energy is wasted and emitted in the form of heat. We shouldn’t use halogen bulbs if we want to save money. Fluorescent lights are more expensive than Halogen lights due to some costly components used in their making.
Recyclability is another crucial factor to consider, as the world is full of E-Waste. We should consider using Recyclable products in our lives. If the light is recyclable, we can re-use it and its parts, which helps stop the overwhelming E-Waste. All the components used in LED lights, such as plastic, aluminum, metals, diodes, etc are entirely recyclable. On the other hand, Fluorescent lights are not adequately recyclable. We cannot recycle Halogen Light bulbs easily along with the regular glass, as the wires in the Halogen bulb aren’t easy to separate. So In terms of Recyclability, LED lights take the lead.
As we know that, Earth is getting more polluted day by day. People also want to use Environmental Friendly devices and appliances to stop the increasing rate of pollution on the planet. The mercury used in Fluorescent lights is harmful to us and the environment. The mercury used in Fluorescent lights is poisonous even if it is in minimal amounts. So we should be careful. Proper Disposal of Fluorescent lights is a big problem for us.
On the Other hand, LED lights are Eco friendly and have no toxic chemicals/gases in them. So we should use LED lights instead of fluorescent lights having poisonous mercury in them. The Halogen Light bulbs contain halogens that degrade air quality when released in the open air and are harmful to the environment. Most people prefer LED lights as they are Eco friendly.
Heat is another important factor to think about while choosing lights. Many lights are available in the market that release a large amount of heat, creating many problems. LED lights don’t become very hot and produce less heat, as no heating process occurs in LED lights to produce light. On the other hand, fluorescent lights waste 30% of their energy as heat. And they increase the overall temperature of the area where we install them. Halogen Light bulbs produce a lot of heat (even more than Fluorescent Light Bulb). They also increase the temperature of the area in which we install them. Halogen Lights emit most of the energy in the form of heat. The Halogen lights are scorching because they require a boiling temperature to make light; touching the Halogen lights can cause a burn. LED lights are better in this case as they produce less heat.
The coverage of LED lights is not much as compared to the Fluorescent lights. LED light emits light at an angle of 180°, so less area is adequately illuminated. We use LED lights at the places where we need recessed lighting. On the other hand, conventional light technology(used in Fluorescent Light bulbs and Halogen Light bulbs) lights up the area at an angle of 360°.In this case, we need to buy deflectors to deflect the light in the desired location and direction. In the case of conventional light technology, light energy is wasted illuminating the areas where light is not required if we don’t buy deflectors to deflect the light.
A Light should be durable to withstand bad weather conditions such as sand storms etc. LED lights are more durable than fluorescent lights. Fluorescent lights consist of fragile glass, which can easily be broken, and LED lights consist of parts made of plastic and aluminum that don’t break easily. The LED light will not hurt you even if you break it mistakenly. You can still use LED lights even if you only break its plastic, covering the internal diodes. LEDs are also shock-resistant, and they also don’t have brittle filaments. Halogen Light bulbs also have fragile glass, which can get damaged easily. A halogen light bulb doesn’t work after its glass gets broken. So LED lights are the most physically durable type of Lights available in the market.
The disposal of electronic devices is a big issue. We can dispose of LED lights easily by throwing them into the trash bin, as they don’t contain harmful chemicals/gas. We can dispose of LED lights by throwing them directly into the household garbage. But it is better to give them to a recycling company to recycle them. This will help us to tackle the increasing rate of E-Waste.
In Contrast, Fluorescent lights contain toxic mercury in them, so we cannot dispose of them easily by throwing them into the household garbage can. We should give our defective fluorescent lights for recycling. Halogen bulbs also can be disposed of by throwing them into a regular household waste bin.
Working in Cold Weather:
Many times we choose the wrong lights for use in extreme weather conditions and face multiple problems. When you’re buying lights for an area where the value of temperature remains negative throughout the year, you should consider whether they work in such weather conditions or not. Fluorescent lights don’t work in freezing weather, as gases are involved in them. So we can’t use fluorescent lights in icy areas. On the other hand, LED lights work even more efficiently in extreme cold weather conditions. The LED lights can work under extreme conditions like freezing temperatures without any problem. We can also use halogen lights even in extreme cold weather conditions. If ice builds up on a halogen bulb, it melts rapidly. Halogen Bulbs can perform well in icy areas. So if you want to buy lights for snowy regions, then you should go for LED as they work well in cold areas and are energy efficient.
UV(Ultra-Violet) rays are harmful to all of us. Even a little exposure to UV rays can cause skin diseases. Fluorescent lights produce harmful UV(Ultraviolet) radiations that can be dangerous for sensitive people. Halogen bulbs also release UV rays that are harmful. LED lights emit a minimal negligible amount of UV rays. So if you want to be safe from UV rays, then you should consider buying LED lights.
Color Changing Lights:
Color-changing lights have become the need of everyone these days. There was a time when we used to replace our lights if we wanted lights of some other color. But now the time has changed a lot. Color-changing lights help us to make our place more advanced and innovative. Only LED and fluorescent color-changing lights are available in the market. Halogen lights don’t offer such an exciting feature. LED color-changing lights are available in the market in a wide variety. The color change is done using different color banks; in multi-chip LEDs in which colors are combined, colors can be changed at the chip level. Fluorescent color-changing lights are not available in a vast variety.
We live in the 21st century, and all the latest appliances and devices have built-in innovative features in them. There was a time when we used to go to the switch to turn off the lights. But now the latest lights have built-in smart features which enable us to control our lights with our smartphones. We are able to change the color of the lights through our phones. We can also control the brightness of lights. LED is the most used technology these days and Only LED lights provide smart features. There are no fluorescent and halogen lights that offer smart features.

Sizes and Shapes Availability:
We use lights at every place. Sometimes we require lights in specific sizes and forms. For example, if we want a light strip of 1-2mm, we don’t have such light strips in every light technology. Only LED light strips are available in the market with a thickness of 1-2mm. Fluorescent lights are not available in every shape and size due to their complex design. Small sizes of Halogen lights are also available in the market. The small size of halogen lamps allows them to use in small optical systems etc. People use Halogen lights in automobile headlights, many types of stage lightings, party lights, etc. They are also the heating elements in the Halogen Ovens and Ceramic cooktops.
The LED lights are taking over the Fluorescent lights because the LED tubes are less harmful, efficient, and brighter. LED lamps are ideal for solar power systems because of their low energy consumption and better performance. In A Customer Survey Conducted by Statista in May 2017 in the US, most residents aged 18-29 years preferred LED bulbs. This shows that the educated youth of the USA prefer LED Lights over all other kinds of lights/bulbs as they are more efficient, durable, recyclable, etc. Due to the Exciting features of LED lights, most people prefer them. . The use of LEDs is spreading on a large scale. People use LED lights in Houses, offices, commercial and industrial lightings.
