LED vs HALOGEN – 5 MAJOR DIFFERENCES

  • Post category:Lighting

If we compare LED vs Halogen, LEDs are clearly outrunning all the conventional lamps such as halogen, fluorescent, metal halide, etc for several reasons: They’re brighter than halogen lamps and often cast a wider model, plus they use less energy, last longer, and have much color options than halogens, which typically are yellowish. What’s more, a lot of people think they look cool.

Halogen was used widely for years because they were cheap to manufacture and simple to replace, but now LEDs are outshining them. So let’s start with the basics and see in LED vs HALOGEN, why LEDs are far better than halogens. 

Even though LED bulbs are more expensive, but make up their cost over time by saving energy and preventing frequent lamp replacements since LEDs last 10 times longer than halogen.

LED vs HALOGEN, HOW DOES IT WORK?​

LED  – A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it.

HALOGEN – Just like with incandescent light bulbs, the electrical current enters the socket and travels up to the tungsten filament, heating up the filament to incandescence. Light is created by running an electric current through the thread until it is white-hot.

01. POWER CONSUMPTION

 If we compare th LED vs Halogen power consumption, Light bulbs are rated in watts (W) to indicate how much energy the light bulb will use as it produces light, and the lumens will give you a measure of how much light it will produce. The LED vs Halogen wattage consumption gives you an idea about the difference and why LEDs are super efficient,

LED

  • LED bulbs use 85% less energy than a halogen bulb while emitting the same amount of light. LED emits a mere 10% of their energy in heat, making them much more energy-efficient and cool to the touch.

HALOGEN

  •  Halogen lights use about 90% of their energy giving off heat, making them a potential fire hazard near combustible materials.

02. BRIGHTNESS

In LED vs Halogen brightness, The luminous flux (lumen) describes the quantity of light emitted by a light source. It is the ratio of the luminous flux to the electrical power consumed (lm/W). A lumen measures the amount of light that comes from a bulb, also known as light bulb brightness. 

LED

  • LEDs are far brighter than halogen bulbs with output of 80-100 lm/W, compared to 16-24 lm/W for halogens. This means that LEDs emit much more light using much less energy.
  • LEDs are dimmable, meaning you can change the level of brightness to the exact level you want. You can also choose to have color-changing options so you can make your lights blue, red, or any other color. 

HALOGEN

  •  Halogen lights emits 16-24 lm/W. Since Halogen lights use about 90% of their energy giving off heat. LEDs can give you a more accurate measurement of actual brightness while halogen wattage basically tells you how hot they are going to get.
  • Halogens can only stay their original brightness and color.

03. LIFE SPAN

Halogen bulbs are a more efficient alternative to incandescent and can last up to twice as long while maintaining their crisp, white light till the end. LEDs are the longest-lasting light bulbs, working for years longer than their counterparts. So in LED vs Halogen bulbs, the life span is,

LED

  • LED bulbs can last up to 25,000 hours, while LED tubes are normally rated for 50,000 hours.
  • LED bulbs last 10X (ten times) longer than halogen.

HALOGEN

  • Halogen bulbs last up to 2,000 hours, which is twice as much as incandescent bulbs but not as long as LED bulbs.

04. COLOR TEMPERATURE

Color temperature is a way to describe the light appearance provided by a light bulb. It is measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. Typically, Kelvin temperatures for commercial and residential lighting applications fall somewhere on a scale from 2000K to 6500K. 

LEDs can be digitally controlled using lighting control systems like DALI, etc

LED

  • LED bulbs are available in various colors and color temperatures from 2700K – 6500K (Warm White to Cool White) in general, to set warm, natural, and cool white ambiances.
  • You can also choose to have color-changing options so you can make your lights blue, red, or any other color. 

HALOGEN

  • Halogen bulbs normally have a colour temperature of 3000K (Warm white), thus providing very few options to set color temperature for offices, residential and other spaces according to ambience.
  •  Halogens can only stay their original brightness and color.

05. Environmental Effects

LED lights are environmentally friendly!  There are essentially zero UV emissions from LED lightbulbs. This also makes LED ideal for using in museums to illuminate items, such as artifacts and old documents.

LED

  • LEDs are free of any harmful chemicals or gases.
  • A leading US-based global business information company, the use of LEDs to illuminate buildings and outdoor spaces has reduced CO2 emissions by nearly 570 million tonnes

HALOGEN

  • Halogen bulbs produce infrared light, which can be damaging to artwork and fabrics
  • Halogen lamps emit significant levels of ultraviolet radiation and should be doped or covered with glass prior to use.

FAQs that people ask when comparing LED Bulbs to Halogen

Are LED bulbs as bright as halogen?

Yes, LED bulbs are as bright as halogen. Not only that, but an LED bulb will produce the same amount of light as a halogen bulb while using 85% less power, so you can replace a 50 Watt halogen bulb with a 7.5 Watt LED.

Are LED bulbs more energy efficient than halogen?

Yes, LED bulbs use 85% less energy than a halogen bulb while emitting the same amount of light.

Do LED bulbs last longer than halogen?

Yes, LED bulbs last a lot longer than halogen bulbs. In fact, LED bulbs last ten times longer than halogen. When you combine that fact with the reduction in energy consumption, you can really see how it pays to choose LED over halogen.

Are LED bulbs cooler than halogen bulbs?

Yes they are. The majority of the energy that an LED bulb uses is converted into light rather than heat, which makes them much cooler to touch. With halogen bulbs, most of the energy is turned into heat, which is why they require so much more energy to produce the same amount of light as a much lower wattage LED.

How many lumens are in a 100 Watt halogen bulb?

A good quality 100 Watt halogen bulb will produce around 1900 lumens. A 100 Watt LED light source will produce around 11,500 lumens!

Can you replace a halogen bulb with an LED bulb?

Yes, you can replace a halogen bulb with an LED. The only instance where this is not possible without an additional driver as in the case of MR16, MR11 and G4 spotlight bulbs.

Can you put LED lights in halogen fittings?

As we’ve already mentioned, most halogen bulbs can be directly replaced with an LED, regardless of the fitting. LED bulbs require a DC electric supply to operate, which means that the standard AC supply in your home needs to be converted to DC in order to power LEDs. With most LED bulbs, the conversion takes place in the light bulb itself, so you can simply replace a halogen bulb with an LED. There are, however, certain types of LED spotlight that do not make the conversion – G4, MR11, and MR16. For these bulbs, you will need to install a driver to convert the AC supply to DC before it reaches the bulb

Are LED light bulbs more expensive than halogen?

Yes, LED bulbs are slightly more expensive than halogen, however, the difference in price is shrinking all the time as LED technology becomes more advanced. Also, as we’ll see when we answer the next question, you more than recoup the increased up-front cost with a substantial increase in lifespan.
