Halogen bulbs are a mixture of inert gas with a small amount of halogen gas.
The addition of Xenon gas into the mix allows the filament to burn brighter to increase light output.
The addition of a blue coating to the bulb will turn the colour of the light to be more white. The downside to this is a small reduction in light intensity.
Bulbs with a higher wattage produce more light but have a shorter lifespan.
Their colour range spans from 2900k to 5900k making them quite diverse bulbs.
These types of upgrade bulbs usually range between 20% to 200% brighter than standard halogen bulbs.
High power bulbs usually last less than 1 year where as long life halogen bulbs can last up to 2 years.
The Drivers’ Trade Off
There is a “light versus style” trade off with halogen bulbs between achieving the most light output and having a whiter coloured light.
A blue coating will make a halogen bulb whiter however this will reduce the light output. This is what we call the Drivers’ Trade Off. If you decide to have whiter halogen lights, just keep in mind that you will be sacrificing the actual light output.
Brighter Lights Will Not Last As Long
Unfortunately, brighter halogen bulbs will not last as long as standard replacements or LED bulbs.
We went in-depth as to how long car bulbs should last in a recent article.
The Main Benefits Of Halogen Upgrade Bulbs
Aside from being a cheaper alternative to most LED headlight bulbs, the main benefit to choosing halogen is that there are no CANBus errors when you change the bulbs over.
Not only are these bulbs perfect for an error free experience but you will also have no bulb holder issues, fully road legal and are a completely low hassle option.
