In this post, we will learn Difference between Halogen & LED. Selecting accurate light bulbs for a home or any building is an important thing for selecting halogen or LEd. These two bulbs come with own features and drawbacks, with color and efficiency. So let’s get started with the Difference between Halogen & LED
Overview of Halogen Lights
- Halogen light is incandescent light bulbs that have a Tungsten filament and halogen gas like iodine or bromine for generating light.
- light passes current through tungsten filament that get heated and releases light
- The bright light releases white light comes with a temperature value of 3000K to 3500K, and is best to use for different applications such as spotlights residential lighting, and automotive headlights.
- Halogen lights are dimmable and offer instant full brightness when switched on. They also lose heat and are less efficient as compared to the latest lighting system
What is LED Lights
LED lights are electric lights that use LEDs to generate light. they aer small semiconductor devices that release light when current passes.
Led lights operate on the principle of converting current into light with the use of electroluminescence.
These lights offer instant illumination have a working life about 25 times higher than incandescent bulbs and have vibration resistance.
LEDs provide flexible design and have different shapes and color combinations.
Either the cost is high but in terms of longer working they cover the cost since made to use for residential, commercial, and automotive, applications for a longer time.

Advantages of Halogen Lights
- This light produces bright white light and is best for projects that need high illumination
- Their working life is about 2500 hours higher than other incandescent bulbs.
- These lamps are dimmable and help to set light intensity based on needs
- It comes in different shapes according to use
Disadvantages of Halogen Lights
- They are less effective for energy efficiency as compared to LEDs. Since uses more energy and generates heat.
- High heating temperatures can damage these devices so they need proper handling
- They can cause a fire since become very hot at the time of working
Advantages of LED Lights
- This light uses less energy and efficient than fluorescent bulbs also reduces bills and releases less carbon.
- They are not made with mercury material or any other hazard that can cause damage to the environment.
- Due to the absence of fragile elements like glass tubes, they can easily handle vibrations and shocks
- They release light in certain directions so used for spotlights
Disadvantages of LED Lights
- They are high-cost devices.
- Their quality is based on manufacturers as well as working life also based on suppliers
- Some leds cause color rendering problems that affect their working.
Differences between LED and Halogen Lights
Cost
- The cost of halogen lights is less but they damage faster than LED lights. Halogen are less efficient. Since just 20 percent of energy used is converted into light and the remaining into heat.
- Either LEDs are high cost but work longer than halogen light and use less energy.
Brightness
- Halogen releases 16 to 24 lumens per watt and LED releases 80 to 100 lumens per watt. So LEDs provide more brightness than halogen light.
Color Temperature
- The unit of color temperature is kelvin scale, halogen light burns about 300K and produces white color temperature as compared to incandescent bulbs which burn at 2700K.
- LEDs come in the range of 1800K to 6500K.
Durability
- LEDs are more durable as compared to halogen. They do not need filament. Filaments are sensitive for vibration and energy surges.
- LED is made with plastic that is durable as compared to halogen bulbs.
Energy Efficiency
- LED bulbs use about 85 percent energy and but halogen are less energy efficient.
Working Life
- LED light can work for about 25000 hours and some high quality can work for 3,600 hours. So they can work for more than 15 years while halogen works for 2 to 3 years.
Risk of Burns
- As we know halogen 80 percent of energy converted into heat. That can cause a fire risk, especially if the wrong lamp is used in the fixture. While LEDs just converted 10 to 20 percent energy into heat so has less chance of fire
Are LED and Halogen Bulbs Always Interchangeable?
- In theory, LEDs are used as replacements for halogen bulbs but there are high voltage and low voltage used so before LED replacement check the voltage of the replaced halogen bulb
- For light fixture uses a low-voltage halogen bulb it means is connected to a transformer. So find the operating voltage of the transformer and ensure the LED connected has the same voltage. That can be either 12V or 24V.
Faqs
How do you tell if a light is LED or halogen?
- The light bulb over 10watt is chances that it is halogen and under10 watt is LEDs
Which is hotter halogen or LED?
- Most of the energy that LED bulb use is transformed into light rather than heat making them less heated so halogen is hotter
Are LED lights better for your eyes than halogen?
- LED lights are less harmful to eye health since there is less blue light and no UV light released through LEDs. The use of LEDs for indoor light is the best option
Do halogen lights use much electricity?
- Average LED light uses 8 watts of power and halogen uses about 90 watts.
What is the difference between LED, incandescent, and halogen lights?
- LED, incandescent, and halogen lights differ in the process they produce light.LED light uses semiconductor materials for producing light, and incandescent and halogen light uses filaments heated through current to generate light. Halogen lights are incandescent light bulbs that use gas to make filaments burn brighter.
