Which is Best: Halogen or Xenon Headlights?
This guide aids buyers in selecting the headlights that are best for them. It will give a definition of a headlight; explain its basic function, as well as the purpose of headlights. It will enumerate the two main types of headlights: halogen and xenon. It will also discuss the lighting technologies behind these types of headlights. This guide will provide an overview of the various advantages and disadvantages of each kind of headlight. It will discuss what type of headlight may be suitable for buyers.
Definition of Headlight
A headlight, also known as a headlamp, is a light that is mounted in the front part of a vehicle, such as a car, van, or truck. It has a reflector and a special lens. Its purpose is to light up the road ahead so that the driver can see it even under dark conditions. The term "headlight" may also be used to refer to the beam of light that is cast by the headlight or headlamp. A headlight must be able to properly illuminate the highway in front of the vehicle even during nighttime, overcast weather, and other situations where visibility is low. It should not cause a strong glare or temporary blindness to drivers of vehicles that are approaching from the opposite side of the road.
A halogen is a monovalent element on the Periodic Table, which easily forms negative ions. There are 5 such halogens - fluorine, chlorine, bromide, iodine, and astatine - but only iodine and bromide are used in lamps. In a halogen light bulb, the filament wears down, shedding tungsten atoms over time. These discarded atoms unite with the halogen gas molecules in the lamp forming tungsten halide, which is then redeposited on the filament. This lengthens lamp life, and prevents blackening.
Xenon is one of the noble gases on the Periodic Table, and it’s odorless and colorless. It works in much the same way as the halogen gases when retarding the filament’s evaporation, but it also produces a bright-white light when stimulated by electricity. Xenon is a more expensive material than any of the halogens.
Both xenon and halogen lamps are more efficient than regular incandescent lamps, but there’s quite a discrepancy between the two.
A halogen lamp’s typical rated life is about 2,000 hours, which is about 2 times longer than that of standard incandescent lights. On average, they produce 10-35 lumens per watt, while an incandescent produces only 8-24. One thing to note: Halogen lights produce the most heat of almost any other light source, and much of the energy they use is given off as heat. If you choose only halogen lights to illuminate a room, you may have to compensate for this heat with air conditioning
A xenon light’s typical rated life is around 10,000 hours, lasting 5 times longer than the average halogen lamp. Because xenon gas glows when excited by electricity, it also takes less energy to achieve the same lumen output. Xenon gas also requires less heat to produce light, so you don’t have to worry about such high energy bills.
It’s no secret halogen lights run hot, which means they’re not suitable for every application. They could possibly damage sensitive artwork or displays with their high temperatures and UV emissions, and could be potentially hazardous if used to light high traffic or enclosed areas like kitchen cabinets.
The halogen light bulbs themselves are also rather delicate. We don’t recommend touching them with bare hands, even when cool. The oil your hands leave behind on the glass will eventually heat up and may cause an imbalance, making the light bulb rupture.
Xenon light bulbs don’t produce as much heat, and emit minimal UV rays. This means they’re safer to use in fragile and high traffic applications. They’re also much more durable – oil doesn’t affect their performance, and they can even withstand unstable voltages.
Halogen lights can be used as accent lights, display lights, and recessed downlights, to name a few. As long as the area of use is fairly tranquil, their performance is quite pleasing.
To start with, xenon lights are perfect for under cabinet lighting, task lighting, cove lighting, and also accent lighting.
It’s easy to switch out your halogen lights for xenon or vice versa, just remember the following:
- The lamps should have the same wattage and voltage ratings.
- The lamps should have the same type of base (bipin, wedge, festoon, etc.)
- The lamps’ glass envelopes should be the same shape and size.
